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!

ARM: add support to dump the kernel page tables This patch allows the kernel page tables to be dumped via a debugfs file, allowing kernel developers to check the layout of the kernel page tables and the verify the various permissions and type settings.

ARM: implement CONFIG_STRICT_DEVMEM by disabling access to RAM via /dev/mem There are very few legitimate use cases, if any, for directly accessing system RAM through /dev/mem. So let's mimic what they do on x86 and forbid it when CONFIG_STRICT_DEVMEM is turned on. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>

ARM: ftrace: enable function graph tracer Add the options to enable the function graph tracer on ARM. Function graph tracer support requires frame pointers, so exclude Thumb-2 and also make sure FRAME_POINTER gets enabled when FUNCTION_GRAPH_TRACER is used, since FUNCTION_TRACER doesn't "select FRAME_POINTER" when ARM_UNWIND is used. Therefore, with GCC 4.4.0+, you get plain function tracing without frame pointers, but you'll need them if you want function graph tracing.

ARM: 7073/1: debug: augment DEBUG_LL Kconfig help to clarify behaviour Enabled DEBUG_LL hardcodes the UART address into the kernel and results in a non-portable kernel image. Since this option is only intended for use when debugging early boot failures, supporting multiple platforms in such a configuration is not the intended use-case.

ARM: 7072/1: debug: use kconfig choice for selecting DEBUG_LL UART Enabling CONFIG_DEBUG_LL (which is required for earlyprintk) hardwires the debug UART address into the kernel, so that we can print before the platform is initialised. If the user inadvertently selects multiple platforms with DEBUG_LL enabled, the UART address may not be correct and will likely cause the kernel to hang in the very early stages of boot. This patch, based on a skeleton from Russell, uses a Kconfig choice for selecting the DEBUG_LL UART, therefore allowing the user to make a choice about the supported platform when DEBUG_LL is enabled.

ARM: zynq: Allow UART1 to be used as DEBUG_LL console. The main UART on the Xilinx ZC702 board is UART1, located at address e0001000. Add a Kconfig option to select this device as the low-level debugging port. This allows the really early boot printouts to reach the USB serial adaptor on this board. For consistency's sake, add a choice entry for UART0 even though it is the the default if UART1 is not selected.

ARM: shmobile: Add early debugging support using SCIF(A) Add serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2. The configuration logic (both Kconfig and #ifdef) is more complicated than one would expect, for several reasons: 1. Not all SoCs have the same serial devices, and they're not always at the same addresses. 2. There are two different types: SCIF and SCIFA. Fortunately they can easily be distinguished by physical address. 3. Not all boards use the same serial port for the console. The defaults correspond to the boards that are supported in mainline. If you want to use a different serial port, just change the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt. 4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END = 0xff000000, and must not conflict with the 2 MiB reserved region at PCI_IO_VIRT_BASE = 0xfee00000. - On SoCs not using the legacy machine_desc.map_io(), debug_ll_io_init() is called by the ARM core code. - On SoCs using the legacy machine_desc.map_io(), debug_ll_io_init() must be called explicitly. Calls are added for r8a7740, r8a7779, sh7372, and sh73a0. This was derived from the r8a7790 version by Laurent Pinchart.

ARM: 7072/1: debug: use kconfig choice for selecting DEBUG_LL UART Enabling CONFIG_DEBUG_LL (which is required for earlyprintk) hardwires the debug UART address into the kernel, so that we can print before the platform is initialised. If the user inadvertently selects multiple platforms with DEBUG_LL enabled, the UART address may not be correct and will likely cause the kernel to hang in the very early stages of boot. This patch, based on a skeleton from Russell, uses a Kconfig choice for selecting the DEBUG_LL UART, therefore allowing the user to make a choice about the supported platform when DEBUG_LL is enabled.

The 'range' of the Kconfig option gets dropped, as users looking at the option must know the uart number on his board. The bottom line is that the build system will report an error if an invalid port number is picked for given SoC.

ARM: shmobile: Add early debugging support using SCIF(A) Add serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2. The configuration logic (both Kconfig and #ifdef) is more complicated than one would expect, for several reasons: 1. Not all SoCs have the same serial devices, and they're not always at the same addresses. 2. There are two different types: SCIF and SCIFA. Fortunately they can easily be distinguished by physical address. 3. Not all boards use the same serial port for the console. The defaults correspond to the boards that are supported in mainline. If you want to use a different serial port, just change the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt. 4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END = 0xff000000, and must not conflict with the 2 MiB reserved region at PCI_IO_VIRT_BASE = 0xfee00000. - On SoCs not using the legacy machine_desc.map_io(), debug_ll_io_init() is called by the ARM core code. - On SoCs using the legacy machine_desc.map_io(), debug_ll_io_init() must be called explicitly. Calls are added for r8a7740, r8a7779, sh7372, and sh73a0. This was derived from the r8a7790 version by Laurent Pinchart.

ARM: debug: provide generic option choices for 8250 and PL01x ports Provide generic option choices for 8250 and PL01x UART ports; these can now be selected by UART type rather than asking about the platform. This means that a kernel configuration user can manually choose the various parameters of the debug UART without resorting to the platform having to encode the possible settings. These two generic options are preferred over further debug entries for these ports; the existing options which refer back to the 8250 and PL01x ports are now considered deprecated.

ARM: 8274/1: Fix DEBUG_LL for multi-platform kernels (without PL01X) When building a multi_v7_defconfig kernel it is not possible to configure DEBUG_LL to use any serial device except a ARM Primecell PL01X, or more accurately and worse, it is possible to configure a different serial device but KConfig does not honour this request. In fact this also overrides the user selection for some of the single platform kernels, for example I don't think DEBUG_LL can be targeted at ICE or semihosted supervisor for ARCH_VERSATILE. This happens because DEBUG_UART_PL01X is automatically enabled by some architectures and this means user decisions made regarding the DEBUG_LL backend will be overridden. Problem is fixed by removing the automatic enabling of this option.

ARM: shmobile: Add early debugging support using SCIF(A) Add serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2. The configuration logic (both Kconfig and #ifdef) is more complicated than one would expect, for several reasons: 1. Not all SoCs have the same serial devices, and they're not always at the same addresses. 2. There are two different types: SCIF and SCIFA. Fortunately they can easily be distinguished by physical address. 3. Not all boards use the same serial port for the console. The defaults correspond to the boards that are supported in mainline. If you want to use a different serial port, just change the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt. 4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END = 0xff000000, and must not conflict with the 2 MiB reserved region at PCI_IO_VIRT_BASE = 0xfee00000. - On SoCs not using the legacy machine_desc.map_io(), debug_ll_io_init() is called by the ARM core code. - On SoCs using the legacy machine_desc.map_io(), debug_ll_io_init() must be called explicitly. Calls are added for r8a7740, r8a7779, sh7372, and sh73a0. This was derived from the r8a7790 version by Laurent Pinchart.

ARM: shmobile: Add early debugging support using SCIF(A) Add serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2. The configuration logic (both Kconfig and #ifdef) is more complicated than one would expect, for several reasons: 1. Not all SoCs have the same serial devices, and they're not always at the same addresses. 2. There are two different types: SCIF and SCIFA. Fortunately they can easily be distinguished by physical address. 3. Not all boards use the same serial port for the console. The defaults correspond to the boards that are supported in mainline. If you want to use a different serial port, just change the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt. 4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END = 0xff000000, and must not conflict with the 2 MiB reserved region at PCI_IO_VIRT_BASE = 0xfee00000. - On SoCs not using the legacy machine_desc.map_io(), debug_ll_io_init() is called by the ARM core code. - On SoCs using the legacy machine_desc.map_io(), debug_ll_io_init() must be called explicitly. Calls are added for r8a7740, r8a7779, sh7372, and sh73a0. This was derived from the r8a7790 version by Laurent Pinchart.

ARM: 8271/1: omap1: Migrate debug_ll macros to use 8250.S The omap1's debug-macro.S is similar to the generic 8250 code. Compared to the 8520 code the omap1 macro automatically determines what UART to use based on breadcrumbs left by the bootloader and automatically copes with the eccentric register layout on OMAP7XX. This patch drops both these features and relies instead on the generic 8250 macros: 1. Dropping support for the bootloader breadcrumbs is identical to the way the migration was handled for OMAP2 (see 808b7e07464d...). 2. Support for OMAP7XX still exists but it must be configured by hand (DEBUG_OMAP7XXUART1/2/3) rather than handled at runtime.

ARM: pxa: fix hang on startup with DEBUG_LL The commit 2111667b4677 ("ARM: pxa: call debug_ll_io_init for earlyprintk") triggers in the current kernel the attached backtrace on PXA/tosa early in the boot time when DEBUG_LL is enabled. It is due to overlap between uart virtual memory defined in DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus mapped by pxa_map_io at the same address, 0xf2100000. As hinted by Arnd, map early virtual memory for low level debug on address 0xf6200000, even if that means 2 virtual mappings will give access to the pxa internal UARTs (FFUART, BTUART, STUART, ...). ------------[ cut here ]------------ kernel BUG at /home/lumag/linux/mm/vmalloc.c:1143!

ARM: 7672/1: uncompress debug support for multiplatform build Instead of giving zero support of uncompress debug for multiplatform build, the patch turns uncompress debug into one part of DEBUG_LL support. When DEBUG_LL is turned on for a particular platform, uncompress debug works too for that platform. OMAP and Tegra are exceptions here. OMAP low-level debug code places data in the .data section, and that is not allowed in decompressor. And Tegra code has reference to variable that's unavailable in decompressor but only in kernel. That's why Kconfig symbol DEBUG_UNCOMPRESS controlling multiplatform uncompress debug support is defined with !DEBUG_OMAP2PLUS_UART && !DEBUG_TEGRA_UART. It creates arch/arm/boot/compressed/debug.S with CONFIG_DEBUG_LL_INCLUDE included there, implements a generic putc() using those macros, which will be built when DEBUG_UNCOMPRESS is defined.

ARM: document DEBUG_UNCOMPRESS Kconfig option This non-user visible option lacked any kind of documentation. This is quite common for non-user visible options; certian people can't understand the point of documenting such options with help text. However, here we have a case in point: developers don't understand the option either, as they were thinking that when the option is not set, the decompressor should produce no output what so ever. This is incorrect, as the purpose of this option is to control whether a multiplatform kernel uses the kernel debugging macros to produce output or not. So let's document this via help rather than commentry to prevent others falling into this misunderstanding. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Solve this by declaring this symbol in tegra.S when it is being built into the decompressor. For the kernel proper, leave the declaration in mach-tegra/common.c as explained in the comment.

ARM: document DEBUG_UNCOMPRESS Kconfig option This non-user visible option lacked any kind of documentation. This is quite common for non-user visible options; certian people can't understand the point of documenting such options with help text. However, here we have a case in point: developers don't understand the option either, as they were thinking that when the option is not set, the decompressor should produce no output what so ever. This is incorrect, as the purpose of this option is to control whether a multiplatform kernel uses the kernel debugging macros to produce output or not. So let's document this via help rather than commentry to prevent others falling into this misunderstanding. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

ARM: 7672/1: uncompress debug support for multiplatform build Instead of giving zero support of uncompress debug for multiplatform build, the patch turns uncompress debug into one part of DEBUG_LL support. When DEBUG_LL is turned on for a particular platform, uncompress debug works too for that platform. OMAP and Tegra are exceptions here. OMAP low-level debug code places data in the .data section, and that is not allowed in decompressor. And Tegra code has reference to variable that's unavailable in decompressor but only in kernel. That's why Kconfig symbol DEBUG_UNCOMPRESS controlling multiplatform uncompress debug support is defined with !DEBUG_OMAP2PLUS_UART && !DEBUG_TEGRA_UART. It creates arch/arm/boot/compressed/debug.S with CONFIG_DEBUG_LL_INCLUDE included there, implements a generic putc() using those macros, which will be built when DEBUG_UNCOMPRESS is defined.

ARM: 7671/1: use Kconfig to select uncompress.h Following the approach handling DEBUG_LL inclusion, the patch creates a Kconfig symbol CONFIG_UNCOMPRESS_INCLUDE for choosing the correct uncompress header. For traditional build, mach/uncompress.h will be included in arch/arm/boot/compressed/misc.c. For multiplatform build, debug/uncompress.h which contains a suite of empty functions will be used. In this way, a platform with particular uncompress.h implementation could choose its own uncompress.h with this Kconfig option.

ARM: 7445/1: mm: update CONTEXTIDR register to contain PID of current process This patch introduces a new Kconfig option which, when enabled, causes the kernel to write the PID of the current task into the PROCID field of the CONTEXTIDR on context switch. This is useful when analysing hardware trace, since writes to this register can be configured to emit an event into the trace stream. The thread notifier for writing the PID is deliberately kept separate from the ASID-writing code so that we can support newer processors using LPAE, where the ASID is stored in TTBR0. As such, the switch_mm code is updated to perform a read-modify-write sequence to ensure that we don't clobber the PID on CPUs using the classic 2-level page tables.

coresight: add CoreSight core layer framework CoreSight components are compliant with the ARM CoreSight architecture specification and can be connected in various topologies to suit a particular SoC tracing needs. These trace components can generally be classified as sources, links and sinks. Trace data produced by one or more sources flows through the intermediate links connecting the source to the currently selected sink. The CoreSight framework provides an interface for the CoreSight trace drivers to register themselves with. It's intended to build up a topological view of the CoreSight components and configure the correct serie of components on user input via sysfs. For eg., when enabling a source, the framework builds up a path consisting of all the components connecting the source to the currently selected sink(s) and enables all of them. The framework also supports switching between available sinks and provides status information to user space applications through the debugfs interface.

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!
