Raw Normal View History

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: 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: davinci: implement DEBUG_LL port choice Apart from the necessity to do this change for multi-platform kernels the previous logic depended on the zImage decompressor to write the physical and virtual address to a magic memory location.
