2010-10-01ARM: implement CONFIG_STRICT_DEVMEM by disabling access to RAM via /dev/memNicolas Pitre
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>
2010-09-02ARM: 6314/1: ftrace: allow build without frame pointers on ARMRabin Vincent
With a new enough GCC, ARM function tracing can be supported without the need for frame pointers. This is essential for Thumb-2 support, since frame pointers aren't available then.

2010-02-24ARM: SAMSUNG: Move plat-s3c Kconfig entries to plat-samsung and plat-s3c24xxBen Dooks
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.

2009-12-09ARM: Add an earlyprintk debug consoleCatalin Marinas
This patch allows an earlyprintk console if CONFIG_DEBUG_LL is enabled, using the printch asm function. The patch is based on the original work by Sascha Hauer.

2009-12-02ARM: 5841/1: a driver for on-chip ETM and ETBAlexander Shishkin
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.

2009-07-24Thumb-2: Add Thumb-2 support to the build filesCatalin Marinas
This patch adds the necessary entries to the Makefile and Kconfig files for building the Thumb-2 kernel. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-06-23[ARM] S3C: Remove unused CONFIG_DEBUG_S3C_PORTBen Dooks
Remove the unused CONFIG_DEBUG_S3C_PORT as we currently only have support for using the S3C UARTs via the low-level debug code. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-02-19[ARM] 5386/2: unwind: Add Makefile and Kconfig entries for ARM stack unwindingCatalin Marinas
This patch also makes the frame pointer default to y only if !ARM_UNWIND. LOCKDEP no longer selects FRAME_POINTER if ARM_UNWIND is enabled. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] CONFIG_DEBUG_STACK_USAGESascha Hauer
In early 2.6 days stack utilization instrumentation was made configurable. Seems that arm misses the DEBUG_STACK_USAGE option. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-22[ARM] 4514/1: S3C: Rename DEBUG_S3C2410_PORT and DEBUG_S3C_UARTBen Dooks
Rename DEBUG_S3C2410_PORT to DEBUG_S3C_PORT as well as DEBUG_S3C2410_UART to DEBUG_S3C_UART as part of the updates to moving to plat-s3c for S3C base support. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-22[ARM] 4513/1: S3C: Rename CONFIG_S3C2410_LOWLEVEL_UART_PORTBen Dooks
Rename CONFIG_S3C2410_LOWLEVEL_UART_PORT to be CONFIG_S3C_LOWLEVEL_UART_PORT as we move to using plat-s3c for base of S3C operations. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-30[ARM] Remove DEBUG_WAITQRussell King
DEBUG_WAITQ appears to have been removed by others, but no one removed the configuration option from ARM. Remote it from both Kconfig.debug and all default configurations. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
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!
