* lib: consolidate DEBUG_STACK_USAGE optionStephen Boyd2011-05-251-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it to lib/Kconfig.debug so each arch doesn't have to define it. This obviously makes the option generic, but that's fine because the config is already used in generic code. It's not obvious to me that sysrq-P actually does anything caution by keeping the most inclusive wording.

* ARM: 6876/1: Kconfig.debug: Remove unused CONFIG_DEBUG_ERRORSStephen Boyd2011-04-141-11/+0
| | | | | | | | | | This config option isn't actually used anywhere and can be safely removed. The last user was traps.c before commit 082f47a ([ARM] always allow dump_stack() to produce a backtrace, 2007-07-05).

| * ARM: Ensure experimental options are so markedRussell King2010-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | It is kernel-wide policy that options depending on EXPERIMENTAL should also have '(EXPERIMENTAL)' in their option text, and options with '(EXPERIMENTAL)' depend on EXPERIMENTAL. Ensure that all ARM options comply with this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | ARM: ftrace: enable function graph tracerRabin Vincent2010-11-191-1/+1
|/ | | | | | | | | | | | | 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: implement CONFIG_STRICT_DEVMEM by disabling access to RAM via /dev/memNicolas Pitre2010-10-011-0/+14
| | | | | | | | | | | | | | | | 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: SAMSUNG: Move plat-s3c Kconfig entries to plat-samsung and plat-s3c24xxBen Dooks2010-02-241-1/+1
| | | | | | | | | | | Move the Kconfig entries from plat-s3c to plat-samsung and plat-s3c24xx as necessary. The S3C_BOOT entries and the DMA configuration can go to plat-samsung. The low-level UART configurations are currently S3C2XX specific and can go to plat-s3c24xx. Eliminating plat-s3c from the build process will be submitted seperately.

| * ARM: 5841/1: a driver for on-chip ETM and ETBAlexander Shishkin2009-12-021-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver implements support for on-chip Embedded Tracing Macrocell and Embedded Trace Buffer. It allows to trigger tracing of kernel execution flow and exporting trace output to userspace via character device and a sysrq combo. Trace output can then be decoded by a fairly simple open source tool [1] which is already sufficient to get the idea of what the kernel is doing.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+109
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!
