[PATCH] ARM: make entry*.S includes more logical Move common includes to entry-header, and file specific includes to the relevant file. Signed-off-by: Russell King <rmk@arm.linux.org.uk>

#include <linux/config.h>
#include <linux/init.h>
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!

[PATCH] ARM: pt_regs offsets Generate pt_regs S_xx offsets from the structure itself instead of #defining them. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
20 years ago
@ Most of the stack format comes from struct pt_regs, but with
@ the addition of 8 bytes for storing syscall args 5 and 6.
[ARM] 3102/1: ARM EABI: stack pointer must be 64-bit aligned after a CPU exception Patch from Nicolas Pitre The ARM EABI says that the stack pointer has to be 64-bit aligned for reasons already mentioned in patch #3101 when calling C functions. We therefore must verify and adjust sp accordingly when taking an exception from kernel mode since sp might not necessarily be 64-bit aligned if the exception occurs in the middle of a kernel function. If the exception occurs while in user mode then no sp fixup is needed as long as sizeof(struct pt_regs) as well as any additional syscall data stack space remain multiples of 8.

@ This _must_ remain a multiple of 8 for EABI.

[PATCH] ARM SMP: convert alignment enable The current vector entry system does not allow for SMP. In order to work around this, we need to eliminate our reliance on the fixed save areas, which breaks the way we enable alignment traps. This patch makes the alignment trap enable code independent of the way we handle the save areas. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
