powerpc: Merge enough to start building in arch/powerpc. This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting. Signed-off-by: Paul Mackerras <paulus@samba.org>

[POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot This puts the knowledge of how to create various sorts of zImage wrappers into a script called "wrapper" that could be used outside of the kernel tree. This changes arch/powerpc/boot so it first builds the files that the wrapper script needs, then runs it to create whatever flavours of zImage are required. This version does uImages as well. The zImage names are changed slightly; zImage.pseries is the one with the PT_NOTE program header entry added, and zImage.pmac is the one without. If the zImage.pseries gets made, it will also get hardlinked to zImage; otherwise, if zImage.pmac is made, it gets hardlinked to zImage. Signed-off-by: Paul Mackerras <paulus@samba.org>

powerpc/Makefile: Use cflags-y/aflags-y for setting endian options When we introduced the little endian support, we added the endian flags to CC directly using override. I don't know the history of why we did that, I suspect no one does. Although this mostly works, it has one bug, which is that CROSS32CC doesn't get -mbig-endian. That means when the compiler is little endian by default and the user is building big endian, vdso32 is incorrectly compiled as little endian and the kernel fails to build. Instead we can add the endian flags to cflags-y/aflags-y, and then append those to KBUILD_CFLAGS/KBUILD_AFLAGS. This has the advantage of being 1) less ugly, 2) the documented way of adding flags in the arch Makefile and 3) it fixes building vdso32 with a LE toolchain.

powerpc: Process dynamic relocations for kernel The following patch implements the dynamic relocation processing for PPC32 kernel. relocate() accepts the target virtual address and relocates the kernel image to the same. Currently the following relocation types are handled : R_PPC_RELATIVE R_PPC_ADDR16_LO R_PPC_ADDR16_HI R_PPC_ADDR16_HA The last 3 relocations in the above list depends on value of Symbol indexed whose index is encoded in the Relocation entry. Hence we need the Symbol Table for processing such relocations. Note: The GNU ld for ppc32 produces buggy relocations for relocation types that depend on symbols. The value of the symbols with STB_LOCAL scope should be assumed to be zero. - Alan Modra Signed-off-by: Suzuki K.

powerpc: Build kernel with -mcmodel=medium Finally remove the two level TOC and build with -mcmodel=medium. Unfortunately we can't build modules with -mcmodel=medium due to the tricks the kernel module loader plays with percpu data: # -mcmodel=medium breaks modules because it uses 32bit offsets from # the TOC pointer to create pointers where possible. Pointers into the # percpu data area are created by this method. # # The kernel module loader relocates the percpu data section from the # original location (starting with 0xd...) to somewhere in the base # kernel percpu data space (starting with 0xc...).

powerpc: Avoid load of static chain register when calling nested functions through a pointer on 64bit The ppc64 ABI has a static chain register (r11) which is only used when calling nested functions through a pointer. Considering that we take a dim view of nested functions in the kernel, we have a lot of unnecessary overhead here. gcc 4.7 has an option to disable loading of r11 so lets use it. If hell freezes over and hipsters manage to litter the kernel with nested functions, gcc will give us an error message and won't simply compile bad code: You cannot take the address of a nested function if you use the -mno-pointers-to-nested-functions option. Furthermore our kernel module trampolines don't setup the static chain register so adding this option and forcing gcc to error out makes even more sense.

powerpc/ftrace: Add Kconfig & Make glue for mprofile-kernel Firstly we add logic to Kconfig to allow a user to choose if they want mprofile-kernel. This has to be user-selectable because only some current toolchains support it. If we enabled it unconditionally we would prevent some users from building the kernel entirely. Arguably it would be nice if we could detect if mprofile-kernel was available, and use it then. However that would violate the principle of least surprise because a user having choosen options such as live patching, would then see them quietly disabled at build time. We also make the user selectable option negative, ie. it disables when selected, so that allyesconfig continues to build on old toolchains. Once we've decided we do want to use mprofile-kernel, we then add a script which checks it actually works. That is because there are versions of gcc that accept the flag but don't generate correct code. Due to the way kconfig works, we can't error out when we detect a non-working toolchain. If we did a user would never be able to modify their config and run oldconfig - because the check would block oldconfig from running. Instead we emit a warning and add a bogus flag to CFLAGS so that the build will fail. Signed-off-by: Torsten Duwe <duwe@suse.de> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

powerpc: Fix 64 bit builds with binutils 2.24 With binutils 2.24, various 64 bit builds fail with relocation errors such as arch/powerpc/kernel/built-in.o: In function `exc_debug_crit_book3e': (.text+0x165ee): relocation truncated to fit: R_PPC64_ADDR16_HI against symbol `interrupt_base_book3e' defined in .text section in arch/powerpc/kernel/built-in.o arch/powerpc/kernel/built-in.o: In function `exc_debug_crit_book3e': (.text+0x16602): relocation truncated to fit: R_PPC64_ADDR16_HI against symbol `interrupt_end_book3e' defined in .text section in arch/powerpc/kernel/built-in.o The assembler maintainer says: I changed the ABI, something that had to be done but unfortunately happens to break the booke kernel code. When building up a 64-bit value with lis, ori, shl, oris, ori or similar sequences, you now should use @high and @higha in place of @h and @ha. @h and @ha (and their associated relocs R_PPC64_ADDR16_HI and R_PPC64_ADDR16_HA) now report overflow if the value is out of 32-bit signed range. ie. @h and @ha assume you're building a 32-bit value. This is needed to report out-of-range -mcmodel=medium toc pointer offsets in @toc@h and @toc@ha expressions, and for consistency I did the same for all other @h and @ha relocs. Replacing @h with @high in one strategic location fixes the relocation errors. This has to be done conditionally since the assembler either supports @h or @high but not both.

powerpc/Makefile: Use cflags-y/aflags-y for setting endian options When we introduced the little endian support, we added the endian flags to CC directly using override. I don't know the history of why we did that, I suspect no one does. Although this mostly works, it has one bug, which is that CROSS32CC doesn't get -mbig-endian. That means when the compiler is little endian by default and the user is building big endian, vdso32 is incorrectly compiled as little endian and the kernel fails to build. Instead we can add the endian flags to cflags-y/aflags-y, and then append those to KBUILD_CFLAGS/KBUILD_AFLAGS. This has the advantage of being 1) less ugly, 2) the documented way of adding flags in the arch Makefile and 3) it fixes building vdso32 with a LE toolchain.

powerpc/Makefile: Drop CONFIG_WORD_SIZE for BITS Commit 2578bfae84a7 ("[POWERPC] Create and use CONFIG_WORD_SIZE") added CONFIG_WORD_SIZE, and suggests that other arches were going to do likewise. But that never happened, powerpc is the only architecture which uses it. So switch to using a simple make variable, BITS, like x86, sh, sparc and tile. It is also easier to spell and simpler, avoiding any confusion about whether it's defined due to ordering of make vs kconfig. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

powerpc: Relocate prom_init.c on 64bit The ppc64 kernel can get loaded at any address which means our very early init code in prom_init.c must be relocatable. We do this with a pretty nasty RELOC() macro that we wrap accesses of variables with. It is very fragile and sometimes we forget to add a RELOC() to an uncommon path or sometimes a compiler change breaks it. 32bit has a much more elegant solution where we build prom_init.c with -mrelocatable and then process the relocations manually. Unfortunately we can't do the equivalent on 64bit and we would have to build the entire kernel relocatable (-pie), resulting in a large increase in kernel footprint (megabytes of relocation data). The relocation data will be marked __initdata but it still creates more pressure on our already tight memory layout at boot. Alan Modra pointed out that the 64bit ABI is relocatable even if we don't build with -pie, we just need to relocate the TOC. This patch implements that idea and relocates the TOC entries of prom_init.c. An added bonus is there are very few relocations to process which helps keep boot times on simulators down. gcc does not put 64bit integer constants into the TOC but to be safe we may want a build time script which passes through the prom_init.c TOC entries to make sure everything looks reasonable.

net: filter: BPF 'JIT' compiler for PPC64 An implementation of a code generator for BPF programs to speed up packet filtering on PPC64, inspired by Eric Dumazet's x86-64 version. Filter code is generated as an ABI-compliant function in module_alloc()'d mem with stackframe & prologue/epilogue generated if required (simple filters don't need anything more than an li/blr). The filter's local variables, M[], live in registers. Supports all BPF opcodes, although "complicated" loads from negative packet offsets (e.g. SKF_LL_OFF) are not yet supported. There are a couple of further optimisations left for future work; many-pass assembly with branch-reach reduction and a register allocator to push M[] variables into volatile registers would improve the code quality further. This currently supports big-endian 64-bit PowerPC only (but is fairly simple to port to PPC32 or LE!).

[POWERPC] bootwrapper: Build multiple cuImages Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image with a fdt blob which means for any given configuration only one dts file can be selected and so support for only one board can be built This moves the selection of the default .dts file out of the kernel config and into the bootwrapper makefile. The makefile chooses which images to build based on the kernel config and the dts source file name is taken directly from the image name. For example "cuImage.ebony" will use "ebony.dts" as the device tree source file. In addition, this patch allows a specific image to be requested from the command line by adding "cuImage.%" and "treeImage.%" targets to the list of valid built targets in arch/powerpc/Makefile. This allows the default dts selection to be overridden. Another advantage to this change is it allows a single defconfig to be supplied for all boards using the same chip family and only differing in the device tree. Important note: This patch adds two new zImage targets; zImage.dtb.% and zImage.dtb.initrd.% for zImages with embedded dtb files. Currently there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc, adder875-redboot and ep8248e. This patch *changes the zImage filenames* for those platforms. ie. 'zImage.ps3' is now 'zImage.dtb.ps3'. This new zImage.dtb targets were added so that the .dts file could be part of the dependancies list for building them.

This will then allow bootable zImages to be created other than in the context of a kernel build. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

powerpc: Merge enough to start building in arch/powerpc. This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting. Signed-off-by: Paul Mackerras <paulus@samba.org>

powerpc/configs: Replace pseries_le_defconfig with a Makefile target using merge_config Rather than continuing to maintain a copy of pseries_defconfig with CONFIG_CPU_LITTLE_ENDIAN enabled, use the generic merge_config script and use an le.config to enable little endian on top of pseries_defconfig without the need for a duplicated _defconfig file. This method will require less maintenance in the future and will ensure that both 'defconfigs' are always in sync. It is worth noting that the seemingly more simple approach of: pseries_le_defconfig: pseries_defconfig $(Q)$(MAKE) le.config Will not work when building using O=builddir. The obvious fix to that: pseries_le_defconfig: $(Q)$(MAKE) -f $(srctree)/Makefile pseries_defconfig le.config Also does not work. This is because if we have for example: config FOO depends on CPU_BIG_ENDIAN select BAR Then BAR will be enabled by the first call to kconfig (via pseries_defconfig), and then will remain enabled after we merge le.config, even though FOO will have been turned off. The solution is to ensure to only invoke the kconfig logic once, after we have merged all the config fragments. This ensures nothing is select'ed on that should then be disabled by the later merged configs. This is done through the explicit call to make olddefconfig Signed-off-by: Cyril Bur <cyrilbur@gmail.com> Reviewed-by: Samuel Mendoza-Jonas <sam.mj@au1.ibm.com> [mpe: Massage change log, fix white space and use ARCH not SRCARCH] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

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.

[POWERPC] bootwrapper: Build multiple cuImages Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image with a fdt blob which means for any given configuration only one dts file can be selected and so support for only one board can be built This moves the selection of the default .dts file out of the kernel config and into the bootwrapper makefile. The makefile chooses which images to build based on the kernel config and the dts source file name is taken directly from the image name. For example "cuImage.ebony" will use "ebony.dts" as the device tree source file. In addition, this patch allows a specific image to be requested from the command line by adding "cuImage.%" and "treeImage.%" targets to the list of valid built targets in arch/powerpc/Makefile. This allows the default dts selection to be overridden. Another advantage to this change is it allows a single defconfig to be supplied for all boards using the same chip family and only differing in the device tree. Important note: This patch adds two new zImage targets; zImage.dtb.% and zImage.dtb.initrd.% for zImages with embedded dtb files. Currently there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc, adder875-redboot and ep8248e. This patch *changes the zImage filenames* for those platforms. ie. 'zImage.ps3' is now 'zImage.dtb.ps3'. This new zImage.dtb targets were added so that the .dts file could be part of the dependancies list for building them.
