Makefile: do not override LC_CTYPE Setting LC_CTYPE=C breaks localized messages in some setups. With only LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not so defined character classes and tolower()/toupper(). The former is not a big issue, because we can assume that e.g. [:alpha:] will always include a-zA-Z and we only ever process ASCII input. The latter seems only affect arch/sh/tools/gen-mach-types, which we can handle separately. So after this patch the meaning of ranges like [a-z], the behavior of sort and join, etc. should be the same everywhere and at the same time gcc should be able to print localized waring and error messages. LC_NUMERIC=C might not be necessary, but setting it doesn't hurt. Reported-by: Simon Horman <horms@verge.net.au> Reported-by: Sergei Trofimovich <slyfox@inbox.ru> Acked-by: H.

Kbuild: Ignore GREP_OPTIONS env variable When building the kernel in a shell which defines GREP_OPTIONS so that grep behavior is modified, we can break the generation of the syscalls table like so: __SYSCALL_COMMON(^[[01;31m^[[K0^[[m^[[K, sys_read, sys_read) __SYSCALL_COMMON(^[[01;31m^[[K1^[[m^[[K, sys_write, sys_write) __SYSCALL_COMMON(^[[01;31m^[[K1^[[m^[[K0, sys_mprotect, sys_mprotect) ... This is just the initial breakage, later we barf when generating modules. In this case, GREP_OPTIONS contains "--color=always" which adds the shell colors markup and completely fudges the headers under ...generated/asm/. Fix that by unexporting the GREP_OPTIONS variable for the whole kernel build as we tend to use grep at a bunch of places.

kbuild: Add extra gcc checks Add a 'W=1' Makefile switch which adds additional checking per build object. The idea behind this option is targeted at developers who, in the process of writing their code, want to do the occasional make W=1 [target.o] and let gcc do more extensive code checking for them. Then, they could eyeball the output for valid gcc warnings about various bugs/discrepancies which are not reported during the normal build process.

kbuild: implement several W= levels Building a kernel with "make W=1" produces far too much noise to be useful. Divide the warning options in three groups: W=1 - warnings that may be relevant and does not occur too often W=2 - warnings that occur quite often but may still be relevant W=3 - the more obscure warnings, can most likely be ignored When building the whole kernel, those levels produce: W=1 - 4859 warnings W=2 - 1394 warnings W=3 - 86666 warnings respectively. Warnings have been counted with Geert's script at http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/linux-log-summary.pl Many warnings occur from .h files so fixing one file may have a nice effect on the total number of warnings. With these changes I am actually tempted to try W=1 now and then. Previously there was just too much noise. Borislav: - make the W= levels exclusive - move very noisy and making little sense for the kernel warnings to W=3 - drop -Woverlength-strings due to useless warning message - copy explanatory text for the different warning levels to 'make help' - recount warnings per level Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Borislav Petkov <bp@alien8.de> Cc: Dave Jones <davej@redhat.com> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Michal Marek <mmarek@suse.cz>

kbuild: change kbuild to not rely on incorrect GNU make behavior The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

Before this patch, when multiple make command goals are specified, each target results in a separate make invocation. With make -j, these invocations may run in parallel, resulting in multiple commands running in the same directory clobbering each others results. I did not try to address make -j for mixed dot-config and no-dot-config targets. Because the order does matter, a solution was not obvious.

I did not try to address make -j for mixed dot-config and no-dot-config targets. Because the order does matter, a solution was not obvious. Perhaps a simple check for MAKEFLAGS having -j and refusing to run would be appropriate. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

kbuild: change kbuild to not rely on incorrect GNU make behavior The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

x86: Default to ARCH=x86 to avoid overriding CONFIG_64BIT It is easy to waste a bunch of time when one takes a 32-bit .config from a test machine and try to build it on a faster 64-bit system, and its existing setting of CONFIG_64BIT=n gets *changed* to match the build host. Similarly, if one has an existing build tree it is easy to trash an entire build tree that way. This is because the default setting for $ARCH when discovered from 'uname' is one of the legacy pre-x86-merge values (i386 or x86_64), which effectively force the setting of CONFIG_64BIT to match. We should default to ARCH=x86 instead, finally completing the merge that we started so long ago. This patch preserves the behaviour of the legacy ARCH settings for commands such as: make ARCH=x86_64 randconfig make ARCH=i386 randconfig ... since making the value of CONFIG_64BIT actually random in that situation is not desirable. In time, perhaps we can retire this legacy use of the old ARCH= values. We already have a way to override values for *any* config option, using $KCONFIG_ALLCONFIG, so it could be argued that we don't necessarily need to keep ARCH={i386,x86_64} around as a special case just for overriding CONFIG_64BIT. We'd probably at least want to add a way to override config options from the command line ('make CONFIG_FOO=y oldconfig') before we talk about doing that though.

ppc64: default build as the merged 'powerpc' architecture After the last merge of the new unified 'powerpc' architecture, ppc64 no longer compiles cleanly as a standalone architecture. Some bits and pieces still exist as files under the old ppc64 hierarchy, but the old "ARCH=ppc64" is dead.

kconfig CROSS_COMPILE option This adds CROSS_COMPILE as a kconfig string so you can store it in .config. Then you can use plain "make" in the configured kernel build directory to do the right cross compilation without setting the command-line or environment variable every time. With this, you can set up different build directories for different kernel configurations, whether native or cross-builds, and then use the simple: make -C /build/dir M=module-source-dir idiom to build modules for any given target kernel, indicating which one by nothing but the build directory chosen. I tried a version that defaults the string with env="CROSS_COMPILE" so that in a "make oldconfig" with CROSS_COMPILE in the environment you can just hit return to store the way you're building it. But the kconfig prompt for strings doesn't give you any way to say you want an empty string instead of the default, so I punted that.

kbuild: revert "save ARCH & CROSS_COMPILE ..." Revert commit 575543347b5baed0ca927cb90ba8807396fe9cc9 It caused following issues: - On architectures where ARCH= setting is used to select between 32 and 64 bit this was no longer possible without "make mrproper" - If ARCH was changed then kbuild refused to run "make mrproper" because ARCH had changed - When CROSS_COMPILE was changed people were asked to run "make mrproper" but kbuild refused to run "make mrproper" because CROSS_COMPILE changed. - Spaces in CROSS_COMPILE was not 'supported' - If an non-existing ARCH= was used kbuild could get stuck Lessons learned: . Despite being simple and straghtforward people uses very different approaches when building the kernel. . CROSS_COMPILE is sometimes used for ccache despite cache being only a CC frontend so one would have expected CC to be used for this purpose. . And obviously this was not tested widely enough.

kbuild: Correctly deal with make options which contain an "s" When using remake, which is based on gnumake, if you invoke an example build as shown below, the build will become silent due to the top level make file incorrectly guessing that the end user wants a silent build because an argument that contained an "s" was used. Here are two examples one with remake and one with straight gnumake. remake --no-extended-errors make --warn-undefined-variables Fix up the top level Makefile to use filter to parse the options that mean silent instead of findstring catching other random arguments containing an "s".

kbuild: fix building with redirected output. Jan Altenberg <jan.altenberg@linutronix.de> reported that building with redirected input like this failed: make O=dir oldconfig bzImage < /dev/null The problem were caused by a make silentoldconfig being run before oldconfig and with a non-recent .config the build failed because silentoldconfig requires non-redirected stdin. Silentoldconfig was run as a side-effect of having the top-level Makefile re-made by make. Introducing an empty rule for the top-level Makefile (and Kbuild.include) fixed the issue.

kbuild: use INSTALLKERNEL to select customized installkernel script Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

gcov: add gcov profiling infrastructure Enable the use of GCC's coverage testing tool gcov [1] with the Linux kernel. gcov may be useful for: * debugging (has this code been reached at all?) * test improvement (how do I change my test to cover these lines?) * minimizing kernel configurations (do I need this option if the associated code is never run?) The profiling patch incorporates the following changes: * change kbuild to include profiling flags * provide functions needed by profiling code * present profiling data as files in debugfs Note that on some architectures, enabling gcc's profiling option "-fprofile-arcs" for the entire kernel may trigger compile/link/ run-time problems, some of which are caused by toolchain bugs and others which require adjustment of architecture code. For this reason profiling the entire kernel is initially restricted to those architectures for which it is known to work without changes. This restriction can be lifted once an architecture has been tested and found compatible with gcc's profiling. Profiling of single files or directories is still available on all platforms (see config help text).

Add '-fno-delete-null-pointer-checks' to gcc CFLAGS Turning on this flag could prevent the compiler from optimising away some "useless" checks for null pointers. Such bugs can sometimes become exploitable at compile time because of the -O2 optimisation. See http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Optimize-Options.html An example that clearly shows this 'problem' is commit 6bf67672. static void __devexit agnx_pci_remove(struct pci_dev *pdev) { struct ieee80211_hw *dev = pci_get_drvdata(pdev); - struct agnx_priv *priv = dev->priv; + struct agnx_priv *priv; AGNX_TRACE; if (!dev) return; + priv = dev->priv; By reverting this patch, and compile it with and without -fno-delete-null-pointer-checks flag, we can see that the check for dev is compiled away. call printk # - testq %r12, %r12 # dev - je .L94 #, movq %r12, %rdi # dev, Clearly the 'fix' is to stop using dev before it is tested, but building with -fno-delete-null-pointer-checks flag at least makes it harder to abuse.

kconfig: move .kernelrelease This moves the .kernelrelease file into include/config directory. Remove its generation from the config step, if the config step doesn't leave a proper .config behind, it triggers a call to silentoldconfig.

kbuild: KERNELRELEASE is only re-defined when buiding the kernel To avoid running setlocalversion as root no longer (re-)define KERNELRELEASE for each run. With this patch KERNELRELEASE is only re-read when we do an actual kernel build. Rationale behind this is "do as little as possible" when executing make install - as root! A new file named .kernelrelease is strored in the root of the kernel tree containing the actual version string. So when we use do a kernel build the .kernelrelease file will be updated. But in all other situations it is left as-is. To make it more visible the kernel now prints out the version being build. Sample: Building kernel 2.6.15-g63b794bf-dirty ... ... The patch also un-exports VERSION PATCHLEVEL SUBLEVEL EXTRAVERSION LOCALVERSION since all users of these are anyway broken - and none is left in the tree.

x86: simplify "make ARCH=x86" and fix kconfig all.config Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in all.config. For a fix the diffstat is nice: 6 files changed, 3 insertions(+), 36 deletions(-) The patch reverts these commits: 0f855aa64b3f63d35a891510cf7db932a435c116 -> kconfig: add helper to set config symbol from environment variable 2a113281f5cd2febbab21a93c8943f8d3eece4d3 -> kconfig: use $K64BIT to set 64BIT with all*config targets Roman Zippel pointed out that kconfig supported string compares so the additional complexity introduced by the above two patches were not needed. With this patch we have following behaviour: # make {allno,allyes,allmod,rand}config [ARCH=...] option \ host arch | 32bit | 64bit ===================================================== ./. | 32bit | 64bit ARCH=x86 | 32bit | 32bit ARCH=i386 | 32bit | 32bit ARCH=x86_64 | 64bit | 64bit The general rule are that ARCH= and native architecture takes precedence over the configuration. So make ARCH=i386 [whatever] will always build a 32-bit kernel no matter what the configuration says. The configuration will be updated to 32-bit if it was configured to 64-bit and the other way around. This behaviour is consistent with previous behaviour so no suprises here. make ARCH=x86 will per default result in a 32-bit kernel but as the only ARCH= value x86 allow the user to select between 32-bit and 64-bit using menuconfig.

kbuild: use INSTALLKERNEL to select customized installkernel script Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

gcov: add gcov profiling infrastructure Enable the use of GCC's coverage testing tool gcov [1] with the Linux kernel. gcov may be useful for: * debugging (has this code been reached at all?) * test improvement (how do I change my test to cover these lines?) * minimizing kernel configurations (do I need this option if the associated code is never run?) The profiling patch incorporates the following changes: * change kbuild to include profiling flags * provide functions needed by profiling code * present profiling data as files in debugfs Note that on some architectures, enabling gcc's profiling option "-fprofile-arcs" for the entire kernel may trigger compile/link/ run-time problems, some of which are caused by toolchain bugs and others which require adjustment of architecture code. For this reason profiling the entire kernel is initially restricted to those architectures for which it is known to work without changes. This restriction can be lifted once an architecture has been tested and found compatible with gcc's profiling. Profiling of single files or directories is still available on all platforms (see config help text).

kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command line It is now possible to assign options to AS, CC and LD on the command line - which is only used when building modules. {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC, LD when building modules without overriding the original value. Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.

tracing: Only print objcopy version warning once from recordmcount If the user has an older version of objcopy, that can not handle converting local symbols to global and vice versa, then some functions will not be part of the dynamic function tracer. The current code in recordmcount.pl will print a warning in this case. Unfortunately, there exists lots of files that may have this issue with older objcopys and this will cause a warning for every file compiled with this issue. This patch solves this overwhelming output by creating a .tmp_quiet_recordmcount file on the first instance the warning is encountered. The warning will not print if this file exists. The temp file is deleted at the beginning of the compile to ensure that the warning will happen once again on new compiles (because the issue is still present).

UAPI: Plumb the UAPI Kbuilds into the user header installation and checking Plumb the UAPI Kbuilds into the user header installation and checking system. As the headers are split the entries will be transferred across from the old Kbuild files to the UAPI Kbuild files. The changes made in this commit are: (1) Exported generated files (of which there are currently four) are moved to uapi/ directories under the appropriate generated/ directory, thus we get: include/generated/uapi/linux/version.h arch/x86/include/generated/uapi/asm/unistd_32.h arch/x86/include/generated/uapi/asm/unistd_64.h arch/x86/include/generated/uapi/asm/unistd_x32.h These paths were added to the build as -I flags in a previous patch. (2) scripts/Makefile.headersinst is now given the UAPI path to install from rather than the old path. It then determines the old path from that and includes that Kbuild also if it exists, thus permitting the headers to exist in either directory during the changeover. I also renamed the "install" variable to "installdir" as it refers to a directory not the install program. (3) scripts/headers_install.pl is altered to take a list of source file paths instead of just their names so that the makefile can tell it exactly where to find each file. For the moment, files can be obtained from one of four places for each output directory: .../include/uapi/foo/ .../include/generated/uapi/foo/ .../include/foo/ .../include/generated/foo/ The non-UAPI paths will be dropped later.

kconfig: fix .config dependencies This fixes one of the worst kbuild warts left - the broken dependencies used to check and regenerate the .config file. This was done via an indirect dependency and the .config itself had an empty command, which can cause make not to reread the changed .config file. Instead of this we generate now a new file include/config/auto.conf from .config, which is used for kbuild and has the proper dependencies. It's also the main make target now for all files generated during this step (and thus replaces include/linux/autoconf.h). This also means we can now relax the syntax requirements for the .config file and we don't have to rewrite it all the time, i.e. silentoldconfig only writes .config now when it's necessary to keep it in sync with the Kconfig files and even this can be suppressed by setting the environment variable KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

kbuild: change kbuild to not rely on incorrect GNU make behavior The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

Turn off -Wmaybe-uninitialized when building with -Os gcc-4.7 and higher add a lot of false positive warnings about potential uses of uninitialized warnings, but only when optimizing for size (-Os). This is the default when building allyesconfig, which turns on CONFIG_CC_OPTIMIZE_FOR_SIZE. In order to avoid getting a lot of patches that initialize such variables and accidentally hide real errors along the way, let's just turn off this warning on the respective gcc versions when building with size optimizations. The -Wmaybe-uninitialized option was introduced in the same gcc version (4.7) that is now causing the false positives, so there is no effect on older compilers. A side effect is that when building with CONFIG_CC_OPTIMIZE_FOR_SIZE, we might now see /fewer/ warnings about possibly uninitialized warnings than with -O2, but that is still much better than seeing warnings known to be bogus.

On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Makefile: fix up CROSS_COMPILE and READABLE_ASM interaction. When the READABLE_ASM cc-option tests were added they were done so prior to the arch Makefile include, resulting in cc-option being run on the host cc instead of the factoring in the cross prefix set up by the architecture. This bumps the include back up so that cc-option actually runs on the compiler that we're building with.

Add option to enable -Wframe-larger-than= on gcc 4.4 Add option to enable -Wframe-larger-than= on gcc 4.4 gcc mainline (upcoming 4.4) added a new -Wframe-larger-than=... option to warn at build time about too large stack frames. Add a config option to enable this warning, since this very useful for the kernel. I choose (somewhat arbitarily) 2048 as default warning threshold for 64bit and 1024 as default for 32bit architectures. With some research and fixing all the code for smaller values these defaults should be probably lowered. With the default allyesconfigs have some new warnings, but I think that is all code that should be just fixed.

stackprotector: Introduce CONFIG_CC_STACKPROTECTOR_STRONG This changes the stack protector config option into a choice of "None", "Regular", and "Strong": CONFIG_CC_STACKPROTECTOR_NONE CONFIG_CC_STACKPROTECTOR_REGULAR CONFIG_CC_STACKPROTECTOR_STRONG "Regular" means the old CONFIG_CC_STACKPROTECTOR=y option. "Strong" is a new mode introduced by this patch. With "Strong" the kernel is built with -fstack-protector-strong (available in gcc 4.9 and later). This option increases the coverage of the stack protector without the heavy performance hit of -fstack-protector-all. For reference, the stack protector options available in gcc are: -fstack-protector-all: Adds the stack-canary saving prefix and stack-canary checking suffix to _all_ function entry and exit. Results in substantial use of stack space for saving the canary for deep stack users (e.g. historically xfs), and measurable (though shockingly still low) performance hit due to all the saving/checking. Really not suitable for sane systems, and was entirely removed as an option from the kernel many years ago. -fstack-protector: Adds the canary save/check to functions that define an 8 (--param=ssp-buffer-size=N, N=8 by default) or more byte local char array. Traditionally, stack overflows happened with string-based manipulations, so this was a way to find those functions. Very few total functions actually get the canary; no measurable performance or size overhead. -fstack-protector-strong Adds the canary for a wider set of functions, since it's not just those with strings that have ultimately been vulnerable to stack-busting. With this superset, more functions end up with a canary, but it still remains small compared to all functions with only a small change in performance. Based on the original design document, a function gets the canary when it contains any of: - local variable's address used as part of the right hand side of an assignment or function argument - local variable is an array (or union containing an array), regardless of array type or length - uses register local variables https://docs.google.com/a/google.com/document/d/1xXBH6rRZue4f296vGt9YQcuLVQHeE516stHwt8M9xyU Find below a comparison of "size" and "objdump" output when built with gcc-4.9 in three configurations: - defconfig 11430641 kernel text size 36110 function bodies - defconfig + CONFIG_CC_STACKPROTECTOR_REGULAR 11468490 kernel text size (+0.33%) 1015 of 36110 functions are stack-protected (2.81%) - defconfig + CONFIG_CC_STACKPROTECTOR_STRONG via this patch 11692790 kernel text size (+2.24%) 7401 of 36110 functions are stack-protected (20.5%) With -strong, ARM's compressed boot code now triggers stack protection, so a static guard was added. Since this is only used during decompression and was never used before, the exposure here is very small. Once it switches to the full kernel, the stack guard is back to normal. Chrome OS has been using -fstack-protector-strong for its kernel builds for the last 8 months with no problems.

ARM: 6312/1: ftrace: allow building without frame pointers With current gcc, compiling with both -pg and -fomit-frame-pointer is not allowed. However, -pg can be used to build without actually specifying -fno-omit-frame-pointer, upon which the default behaviour for the target will be used. On ARM, it is not possible to build a Thumb-2 kernel with -fno-omit-frame-pointer (FRAME_POINTERS depends on !THUMB2_KERNEL). In order to support ftrace for Thumb-2, we need to be able to allow a combination of FUNCTION_TRACER and !FRAME_POINTER. We do this by omitting -fomit-frame-pointer if ftrace is enabled.

This will properly generate the debugging info for .S files when CONFIG_DEBUG_INFO=y. It seems current gcc does not pass a '--gdwarf-2' option on to the assembler when '-gdwarf-2' is on its command line (note the differece in the gcc and as flags). This change provides the correct assembler flag to gcc, and so does not rely on gcc to emit a flag for the assembler.

Kbuild: Add option to set -femit-struct-debug-baseonly Newer gcc has a -femit-struct-debug-baseonly option that dramatically reduces the size of object files with debug info. What it does is to only emit type information for structures when the structures are defined in the same file or in a header file. This means the type information for most headers are not included. This is not good when the type information is actually needed (e.g. with kgdb or systemtap) But often kernel hackers only care about line numbers and don't need all the type information anyways. In this case setting the option can be a big win: A build dir for a specific x86-64 configuration with gcc 4.5 shrunk from 2.3G to 1.2G. The compilation was also nearly a minute faster.

Kbuild: Disable var tracking with CONFIG_DEBUG_INFO_REDUCED Newer gcc enables the var-tracking pass with -g to keep track which registers contain which variables. This is one of the slower passes in gcc. With reduced debug info (aimed at objdump -S, but not using a full debugger) we don't need this fine grained tracking. But it was still enabled because -g was enabled. Disable it explicitely for DEBUG_INFO_REDUCED. On my 8T workstation this gives me about a 12 second gain in building a reasonable kernel config (2min16 vs 2min28) with DEBUG_INFO_REDUCED. With full DEBUG_INFO it takes 2min46 The actual improvement in user time taken by the compiler is much higher (all CPU combined user time 15min5s vs 16m30 before) but the usual amdahl bottleneck on the linker prevents more speedup. It still saves some more energy and keeps cycles for other things. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Michal Marek <mmarek@suse.cz>

ftrace: Add -mfentry to Makefile on function tracer Thanks to Andi Kleen, gcc 4.6.0 now supports -mfentry for x86 (and hopefully soon for other archs). What this does is to have the function profiler start at the beginning of the function instead of after the stack is set up. As plain -pg (mcount) is called after the stack is set up, and in some cases can have issues with the function graph tracer. It also requires frame pointers to be enabled. The -mfentry now calls __fentry__ at the beginning of the function. This allows for compiling without frame pointers and even has the ability to access parameters if needed. If the architecture and the compiler both support -mfentry then use that instead. Link: http://lkml.kernel.org/r/20120807194059.392617243@goodmis.org Acked-by: H.

[ This code has been highly hacked by Steven Rostedt and Ingo Molnar, so don't blame Arnaldo for all of this ;-) ] Update: It is now possible to register more than one ftrace function. If only one ftrace function is registered, that will be the function that ftrace calls directly.

Use --build-id ld option This change passes the --build-id when linking the kernel and when linking modules, if ld supports it. This is a new GNU ld option that synthesizes an ELF note section inside the read-only data. The note in this section contains unique identifying bits called the "build ID", which are generated so as to be different for any two linked ELF files that aren't identical. The build ID can be recovered from stripped files, memory dumps, etc. and used to look up the original program built, locate debuginfo or other details or history associated with it. For normal program linking, the compiler passes --build-id to ld by default, but the option is needed when using ld directly as we do.

kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command line It is now possible to assign options to AS, CC and LD on the command line - which is only used when building modules. {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC, LD when building modules without overriding the original value. Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.

Use --build-id ld option This change passes the --build-id when linking the kernel and when linking modules, if ld supports it. This is a new GNU ld option that synthesizes an ELF note section inside the read-only data. The note in this section contains unique identifying bits called the "build ID", which are generated so as to be different for any two linked ELF files that aren't identical. The build ID can be recovered from stripped files, memory dumps, etc. and used to look up the original program built, locate debuginfo or other details or history associated with it. For normal program linking, the compiler passes --build-id to ld by default, but the option is needed when using ld directly as we do.

kbuild: dtbs_install: new make target Unlike other build products in the Linux kernel, there is no 'make *install' mechanism to put devicetree blobs in a standard place. This commit adds a new 'dtbs_install' make target which copies all of the dtbs into the INSTALL_DTBS_PATH directory. INSTALL_DTBS_PATH can be set before calling make to change the default install directory. If not set then it defaults to: $INSTALL_PATH/dtbs/$KERNELRELEASE. This is done to keep dtbs from different kernel versions separate until things have settled down. Once the dtbs are stable, and not so strongly linked to the kernel version, the devicetree files will most likely move to their own repo. Users will need to upgrade install scripts at that time. v7: (reworked by Grant Likely) - Moved rules from arch/arm/Makefile to arch/arm/boot/dts/Makefile so that each dtb install could have a separate target and be reported as part of the make output. - Fixed dependency problem to ensure $KERNELRELEASE is calculated before attempting to install - Removed option to call external script. Copying the files should be sufficient and a build system can post-process the install directory. Despite the fact an external script is used for installing the kernel, I don't think that is a pattern that should be encouraged. I would rather see buildroot type tools post process the install directory to rename or move dtb files after installing to a staging directory. - Plus it is easy to add a hook after the fact without blocking the rest of this feature. - Move the helper targets into scripts/Makefile.lib with the rest of the common dtb rules Signed-off-by: Jason Cooper <jason@lakedaemon.net> Signed-off-by: Grant Likely <grant.likely@linaro.org> Cc: Michal Marek <mmarek@suse.cz> Cc: Russell King <linux@arm.linux.org.uk> Cc: Rob Herring <robh+dt@kernel.org>

./Makefile: export initial ramdisk compression config option Make menuconfig allows one to choose compression format of an initial ramdisk image. But this choice does not result in duly compressed ramdisk image. Because - $ make install - does not pass on the selected compression choice to the dracut(8) tool, which creates the initramfs file. dracut(8) generates the image with the default compression, ie. gzip(1). This patch exports the selected compression option to a sub-shell environment, so that it could be used by dracut(8) tool to generate appropriately compressed initramfs images. There isn't a straightforward way to pass on options to dracut(8) via positional parameters. Because it is indirectly invoked at the end of a $ make install sequence. # make install -> arch/$arch/boot/Makefile -> arch/$arch/boot/install.sh -> /sbing/installkernel ... -> /sbin/new-kernel-pkg ... -> /sbin/dracut ...

Don't set the INITRD_COMPRESS environment variable automatically Commit 1bf49dd4be0b ("./Makefile: export initial ramdisk compression config option") started setting the INITRD_COMPRESS environment variable depending on which decompression models the kernel had available. That is completely broken. For example, we by default have CONFIG_RD_LZ4 enabled, and are able to decompress such an initrd, but the user tools to *create* such an initrd may not be availble. So trying to tell dracut to generate an lz4-compressed image just because we can decode such an image is completely inappropriate.

The Makefile fragments used to link vmlinux has over the years seen far too many changes and the logic had become hard to follow. As the process by nature is serialized there was nothing gained including this in the Makefile. "um" has special link requirments - and the only way to handle this was to hard-code the linking of "um" in the script.

The Makefile fragments used to link vmlinux has over the years seen far too many changes and the logic had become hard to follow. As the process by nature is serialized there was nothing gained including this in the Makefile. "um" has special link requirments - and the only way to handle this was to hard-code the linking of "um" in the script. This was better than trying to modularize it only for the benefit of "um" anyway.

rpm-pkg: Do not package the whole source directory The source tree can contain lots of uninteresting data like tag or cscope files, packaging which slows down make rpm needlessly. It can also break the build, if the tree contains an unrelated file named *.spec. The downside of this change is that new subdirectories have to be added to the KBUILD_ALLDIRS variable in the top-level Makefile. The upside is that the behavior is more predictable.

allow stripping of generated symbols under CONFIG_KALLSYMS_ALL Building upon parts of the module stripping patch, this patch introduces similar stripping for vmlinux when CONFIG_KALLSYMS_ALL=y. Using CONFIG_KALLSYMS_STRIP_GENERATED reduces the overhead of CONFIG_KALLSYMS_ALL from 245k/310k to 65k/80k for the (i386/x86-64) kernels I tested with. The patch also does away with the need to special case the kallsyms- internal symbols by making them available even in the first linking stage. While it is a generated file, the patch includes the changes to scripts/genksyms/keywords.c_shipped, as I'm unsure what the procedure here is.

docsrc: build Documentation/ sources Currently source files in the Documentation/ sub-dir can easily bit-rot since they are not generally buildable, either because they are hidden in text files or because there are no Makefile rules for them. This needs to be fixed so that the source files remain usable and good examples of code instead of bad examples. Add the ability to build source files that are in the Documentation/ dir. Add to Kconfig as "BUILD_DOCSRC" config symbol. Use "CONFIG_BUILD_DOCSRC=1 make ..." to build objects from the Documentation/ sources. Or enable BUILD_DOCSRC in the *config system. However, this symbol depends on HEADERS_CHECK since the header files need to be installed (for userspace builds).

Create a dedicated vmlinux.o file used only for section mismatch checks that uses the defualt linker script so section does not get renamed. The vmlinux.o may later be used as part of the the final link of vmlinux but for now it is used fo section mismatch only.

With this patch KERNELRELEASE is only re-read when we do an actual kernel build. Rationale behind this is "do as little as possible" when executing make install - as root! A new file named .kernelrelease is strored in the root of the kernel tree containing the actual version string. So when we use do a kernel build the .kernelrelease file will be updated. But in all other situations it is left as-is. To make it more visible the kernel now prints out the version being build. Sample: Building kernel 2.6.15-g63b794bf-dirty ... ...

kconfig: fix .config dependencies This fixes one of the worst kbuild warts left - the broken dependencies used to check and regenerate the .config file. This was done via an indirect dependency and the .config itself had an empty command, which can cause make not to reread the changed .config file. Instead of this we generate now a new file include/config/auto.conf from .config, which is used for kbuild and has the proper dependencies. It's also the main make target now for all files generated during this step (and thus replaces include/linux/autoconf.h). This also means we can now relax the syntax requirements for the .config file and we don't have to rewrite it all the time, i.e. silentoldconfig only writes .config now when it's necessary to keep it in sync with the Kconfig files and even this can be suppressed by setting the environment variable KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

kbuild: asm-generic support There is an increasing amount of header files shared between individual architectures in asm-generic. To avoid a lot of dummy wrapper files that just include the corresponding file in asm-generic provide some basic support in kbuild for this. With the following patch an architecture can maintain a list of files in the file arch/$(ARCH)/include/asm/Kbuild To use a generic file just add: generic-y += <name-of-header-file.h> For each file listed kbuild will generate the necessary wrapper in arch/$(ARCH)/include/generated/asm. When installing userspace headers a wrapper is likewise created. The original inspiration for this came from the unicore32 patchset - although a different method is used. The patch includes several improvements from Arnd Bergmann. Michael Marek contributed Makefile.asm-generic.

x86, realmode: 16-bit real-mode code support for relocs tool A new option is added to the relocs tool called '--realmode'. This option causes the generation of 16-bit segment relocations and 32-bit linear relocations for the real-mode code. When the real-mode code is moved to the low-memory during kernel initialization, these relocation entries can be used to relocate the code properly. In the assembly code 16-bit segment relocations must be relative to the 'real_mode_seg' absolute symbol. Linear relocations must be relative to a symbol prefixed with 'pa_'. 16-bit segment relocation is used to load cs:ip in 16-bit code. Linear relocations are used in the 32-bit code for relocatable data references. They are declared in the linker script of the real-mode code. The relocs tool is moved to arch/x86/tools/relocs.c, and added new target archscripts that can be used to build scripts needed building an architecture. be compiled before building the arch/x86 tree.

kbuild: rename prepare to archprepare to fix dependency chain When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

kbuild: full dependency check on asm-offsets.h Building asm-offsets.h has been moved to a seperate Kbuild file located in the top-level directory. This allow us to share the functionality across the architectures. The old rules in architecture specific Makefiles will die in subsequent patches. Furhtermore the usual kbuild dependency tracking is now used when deciding to rebuild asm-offsets.s. So we no longer risk to fail a rebuild caused by asm-offsets.c dependencies being touched. With this common rule-set we now force the same name across all architectures. Following patches will fix the rest. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

KBuild: silence "'scripts/unifdef' is up to date." While changing our build system over to use the headers_install target as part of our klibc build, the following message started showing up in our logs: make[2]: `scripts/unifdef' is up to date. It turns out that the build blindly invokes a recursive make on this target, which causes make to emit this message when the target is already up to date. This isn't seen for most targets as the rest of the build relies primarily on the default target and on PHONY targets when invoking make recursively. Silence the above message when building unifdef as part of headers_install by hiding it behind a new PHONY target called "build_unifdef" that has an empty recipe.

UAPI: Plumb the UAPI Kbuilds into the user header installation and checking Plumb the UAPI Kbuilds into the user header installation and checking system. As the headers are split the entries will be transferred across from the old Kbuild files to the UAPI Kbuild files. The changes made in this commit are: (1) Exported generated files (of which there are currently four) are moved to uapi/ directories under the appropriate generated/ directory, thus we get: include/generated/uapi/linux/version.h arch/x86/include/generated/uapi/asm/unistd_32.h arch/x86/include/generated/uapi/asm/unistd_64.h arch/x86/include/generated/uapi/asm/unistd_x32.h These paths were added to the build as -I flags in a previous patch. (2) scripts/Makefile.headersinst is now given the UAPI path to install from rather than the old path. It then determines the old path from that and includes that Kbuild also if it exists, thus permitting the headers to exist in either directory during the changeover. I also renamed the "install" variable to "installdir" as it refers to a directory not the install program. (3) scripts/headers_install.pl is altered to take a list of source file paths instead of just their names so that the makefile can tell it exactly where to find each file. For the moment, files can be obtained from one of four places for each output directory: .../include/uapi/foo/ .../include/generated/uapi/foo/ .../include/foo/ .../include/generated/foo/ The non-UAPI paths will be dropped later.

Useful for distros (and people with too much time on their hands) that support a ton of architectures, headers_check_all is to headers_check as headers_install_all is to headers_install Signed-off-by: Mike Frysinger <vapier@gentoo.org> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Basic implementation of 'make headers_check' Based on the 'headers_install' target, this performs a basic sanity check on the exported headers -- so far only checking that they do not include any other headers which aren't selected for import, but easily extendable.

UAPI: Plumb the UAPI Kbuilds into the user header installation and checking Plumb the UAPI Kbuilds into the user header installation and checking system. As the headers are split the entries will be transferred across from the old Kbuild files to the UAPI Kbuild files. The changes made in this commit are: (1) Exported generated files (of which there are currently four) are moved to uapi/ directories under the appropriate generated/ directory, thus we get: include/generated/uapi/linux/version.h arch/x86/include/generated/uapi/asm/unistd_32.h arch/x86/include/generated/uapi/asm/unistd_64.h arch/x86/include/generated/uapi/asm/unistd_x32.h These paths were added to the build as -I flags in a previous patch. (2) scripts/Makefile.headersinst is now given the UAPI path to install from rather than the old path. It then determines the old path from that and includes that Kbuild also if it exists, thus permitting the headers to exist in either directory during the changeover. I also renamed the "install" variable to "installdir" as it refers to a directory not the install program. (3) scripts/headers_install.pl is altered to take a list of source file paths instead of just their names so that the makefile can tell it exactly where to find each file. For the moment, files can be obtained from one of four places for each output directory: .../include/uapi/foo/ .../include/generated/uapi/foo/ .../include/foo/ .../include/generated/foo/ The non-UAPI paths will be dropped later.

kbuild: implement modules.order When multiple built-in modules (especially drivers) provide the same capability, they're prioritized by link order specified by the order listed in Makefile. This implicit ordering is lost for loadable modules. When driver modules are loaded by udev, what comes first in modules.alias file is selected. However, the order in this file is indeterministic (depends on filesystem listing order of installed modules). This causes confusion. The solution is two-parted. This patch updates kbuild such that it generates and installs modules.order which contains the name of modules ordered according to Makefile. The second part is update to depmod such that it generates output files according to this file. Note that both obj-y and obj-m subdirs can contain modules and ordering information between those two are lost from beginning. Currently obj-y subdirs are put before obj-m subdirs. Sam Ravnborg cleaned up Makefile modifications and suggested using awk to remove duplicate lines from modules.order instead of using separate C program.

kbuild: rename prepare to archprepare to fix dependency chain When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

Revert "Makefile: Fix install error with make -j option" This reverts commit d2aae8477cd00325bb7c7c7e95be488088900c48. It is completely and utterly broken. Module install should not build any files, and adding broken dependencies to "help" it build files is complete and utter sh*t. The kernel should not be built by root, and "make install" and "make module_install" (that for obvious reasons need to be run as root) absolutely must not build any files. They should only ever copy the already-built files over. So having dependencies for the install targets is wrong, wrong, wrong. If you try to install a kernel without building it first, you *should* get errors. The build system shouldn't try to help root build the files.

kbuild: asm-generic support There is an increasing amount of header files shared between individual architectures in asm-generic. To avoid a lot of dummy wrapper files that just include the corresponding file in asm-generic provide some basic support in kbuild for this. With the following patch an architecture can maintain a list of files in the file arch/$(ARCH)/include/asm/Kbuild To use a generic file just add: generic-y += <name-of-header-file.h> For each file listed kbuild will generate the necessary wrapper in arch/$(ARCH)/include/generated/asm. When installing userspace headers a wrapper is likewise created. The original inspiration for this came from the unicore32 patchset - although a different method is used. The patch includes several improvements from Arnd Bergmann. Michael Marek contributed Makefile.asm-generic.

It has the same return values as diff(1). This was written specifically to support adding the skein and threefish cryto drivers to the staging tree. I needed a programmatic way to confirm that commits changing >90% of the lines didn't inadvertently change the code. Temporary files (objdump output) are stored in /path/to/linux/.tmp_objdiff 'make mrproper' will remove this directory.

kbuild: unconditionally clobber include/linux/version.h on distclean As of v3.7, the UAPI changes relocated headers around such that the kernel version header lived in a new place. If a person is bisecting and if you go back to pre-UAPI days, you will create an include/linux/version.h -- then if you checkout a post-UAPI kernel, and even run "make distclean" it still won't delete that old version file. So you get a situation like this: $ grep -R LINUX_VERSION_CODE include/ include/generated/uapi/linux/version.h:#define LINUX_VERSION_CODE 200192 include/linux/version.h:#define LINUX_VERSION_CODE 132646 The value in that second line is representative of a v2.6.38 version. And it will be sourced/used, hence leading to strange behaviours, such as drivers/staging content (which typically hasn't been purged of version ifdefs) failing to build. Since it is a subtle mode of failure, lets always clobber the old file when doing a distclean.

kbuild: KERNELRELEASE is only re-defined when buiding the kernel To avoid running setlocalversion as root no longer (re-)define KERNELRELEASE for each run. With this patch KERNELRELEASE is only re-read when we do an actual kernel build. Rationale behind this is "do as little as possible" when executing make install - as root! A new file named .kernelrelease is strored in the root of the kernel tree containing the actual version string. So when we use do a kernel build the .kernelrelease file will be updated. But in all other situations it is left as-is. To make it more visible the kernel now prints out the version being build. Sample: Building kernel 2.6.15-g63b794bf-dirty ... ...

The new target calls the 'coccicheck' front-end in the 'scripts' directory with the MODE argument. Every SmPL file in the subdirectories of 'scripts/coccinelle' is then given to the front-end and applied to the entire source tree. The four modes behave as follows: 'report' generates a list in the following format: file:line:column-column: message 'patch' proposes a fix, when possible. 'context' highlights lines of interest and their context in a diff-like style. Lines of interest are indicated with '-'. 'org' generates a report in the Org mode format of Emacs.

kbuild: show defconfig subdirs in make help PowerPC will start moving board defconfigs into subarch-specific subdirs soon. "make help" currently does not look in subdirs to find the defconfigs to show. This is partially a good thing, since there are way too many defconfigs for one list. This patch makes the main "make help" display something like help-40x - Show 40x-specific targets help-44x - Show 44x-specific targets help-boards - Show all of the above and wires up stuff so those new help-* commands actually work.

kbuild: implement several W= levels Building a kernel with "make W=1" produces far too much noise to be useful. Divide the warning options in three groups: W=1 - warnings that may be relevant and does not occur too often W=2 - warnings that occur quite often but may still be relevant W=3 - the more obscure warnings, can most likely be ignored When building the whole kernel, those levels produce: W=1 - 4859 warnings W=2 - 1394 warnings W=3 - 86666 warnings respectively. Warnings have been counted with Geert's script at http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/linux-log-summary.pl Many warnings occur from .h files so fixing one file may have a nice effect on the total number of warnings. With these changes I am actually tempted to try W=1 now and then. Previously there was just too much noise. Borislav: - make the W= levels exclusive - move very noisy and making little sense for the kernel warnings to W=3 - drop -Woverlength-strings due to useless warning message - copy explanatory text for the different warning levels to 'make help' - recount warnings per level Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Borislav Petkov <bp@alien8.de> Cc: Dave Jones <davej@redhat.com> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Michal Marek <mmarek@suse.cz>

Commit 88d7be031f9f975bb3f50a0b5ef3796a671e7edf (kbuild: Use a single clean rule for kernel and external modules) introduced the "$(or" construct, which requires make 3.81. This causes "make clean" to malfunction when it is used with external modules. Replace "$(or" with an equivalent "$(if" expression, to restore backward compatibility.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

tags and cscope support really belongs in a shell script as they do not benefit from the make functionality. Moving the support to a shell script has several benefits: - The readability of the code has increased a lot - More people is able to extend the tags support - We see less changes to the top-level Makefile The shell script version includes improvements from: Alexey Dobriyan <adobriyan@gmail.com> (jump to kconfig symbols) Alexey Dobriyan <adobriyan@gmail.com> (drop ./ in paths) Ian Campbell <ijc@hellion.org.uk> (simplified find algorithms) This version has a few caveats: => It does not support ALLSOURCE_ARCHS - it is easy to add if it is really used => It assumes all archs have moved to arch/$ARCH/include - until that happens we have a few additional hits in the archs Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Alexey Dobriyan <adobriyan@gmail.com> Tested-by: Ian Campbell <ijc@hellion.org.uk>

Add a target to use the Coccinelle checker A 'coccicheck' target is added. It can be called with four different modes. Each one generates a different kind of output, i.e. context, patch, org, report, according to the corresponding mode to be activated. The new target calls the 'coccicheck' front-end in the 'scripts' directory with the MODE argument. Every SmPL file in the subdirectories of 'scripts/coccinelle' is then given to the front-end and applied to the entire source tree. The four modes behave as follows: 'report' generates a list in the following format: file:line:column-column: message 'patch' proposes a fix, when possible. 'context' highlights lines of interest and their context in a diff-like style. Lines of interest are indicated with '-'. 'org' generates a report in the Org mode format of Emacs.

kbuild: KERNELRELEASE is only re-defined when buiding the kernel To avoid running setlocalversion as root no longer (re-)define KERNELRELEASE for each run. With this patch KERNELRELEASE is only re-read when we do an actual kernel build. Rationale behind this is "do as little as possible" when executing make install - as root! A new file named .kernelrelease is strored in the root of the kernel tree containing the actual version string. So when we use do a kernel build the .kernelrelease file will be updated. But in all other situations it is left as-is. To make it more visible the kernel now prints out the version being build. Sample: Building kernel 2.6.15-g63b794bf-dirty ... ...

kbuild: support building individual files for external modules Support building individual files when dealing with separate modules. So say you have a module named "foo" which consist of two .o files bar.o and fun.o. You can then do: make -C $KERNELSRC M=`pwd` bar.o make -C $KERNELSRC M=`pwd` bar.lst make -C $KERNELSRC M=`pwd` bar.i make -C $KERNELSRC M=`pwd` / <= will build all .o files and link foo.o make -C $KERNELSRC M=`pwd` foo.ko <= will build the module and do the modpost step to create foo.ko The above will also work if the external module is placed in a subdirectory using a hirachy of kbuild files.

kbuild: support for %.symtypes files Here is a patch that adds a new -T option to genksyms for generating dumps of the type definition that makes up the symbol version hashes. This allows to trace modversion changes back to what caused them. The dump format is the name of the type defined, followed by its definition (which is almost C): s#list_head struct list_head { s#list_head * next , * prev ; } The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef. The exported symbols do not define types, and thus do not have an x# prefix: nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 ) The symbol type defintion of a single file can be generated with: make fs/jbd/journal.symtypes If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that export symbols are generated. The single *.symtypes files can be combined into a single file after a kernel build with a script like the following: for f in $(find -name '*.symtypes' | sort); do f=${f#./} echo "/* ${f%.symtypes}.o */" cat $f echo done \ | sed -e '\:UNKNOWN:d' \ -e 's:[,;] }:}:g' \ -e 's:\([[({]\) :\1:g' \ -e 's: \([])},;]\):\1:g' \ -e 's: $::' \ $f \ | awk ' /^.#/ { if (defined[$1] == $0) { print $1 next } defined[$1] = $0 } { print } ' When the kernel ABI changes, diffing individual *.symtype files, or the combined files, against each other will show which symbol changes caused the ABI changes. This can save a tremendous amount of time. Dump the types that make up modversions Signed-off-by: Andreas Gruenbacher <agruen@suse.de> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

CONFIG_SYMBOL_PREFIX: cleanup. We have CONFIG_SYMBOL_PREFIX, which three archs define to the string "_". But Al Viro broke this in "consolidate cond_syscall and SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to do so. Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to prefix it so something. So various places define helpers which are defined to nothing if CONFIG_SYMBOL_PREFIX isn't set: 1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX. 2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym) 3) include/linux/export.h defines MODULE_SYMBOL_PREFIX. 4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7) 5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym) 6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX 7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version for pasting. (arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too). Let's solve this properly: 1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX. 2) Make linux/export.h usable from asm. 3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR(). 4) Make everyone use them.
