Add core support for ARMv6/v7 big-endian

2009-05-30T13:00:18Z

Starting with ARMv6, the CPUs support the BE-8 variant of big-endian (byte-invariant). This patch adds the core support: - setting of the BE-8 mode via the CPSR.E register for both kernel and user threads - big-endian page table walking - REV used to rotate instructions read from memory during fault processing as they are still little-endian format - Kconfig and Makefile support for BE-8. The --be8 option must be passed to the final linking stage to convert the instructions to little-endian Signed-off-by: Catalin Marinas

[ARM] 5418/1: restore lr before leaving mcount

2009-03-05T13:47:15Z

gcc seems to expect that lr isn't clobbered by mcount, because for a function starting with: static int func(void) { void *ra = __builtin_return_address(0); printk(KERN_EMERG "__builtin_return_address(0) = %pS\n", ra) ... the following assembler is generated by gcc 4.3.2: 0: e1a0c00d mov ip, sp 4: e92dd810 push {r4, fp, ip, lr, pc} 8: e24cb004 sub fp, ip, #4 ; 0x4 c: ebfffffe bl 0 10: e59f0034 ldr r0, [pc, #52] 14: e1a0100e mov r1, lr 18: ebfffffe bl 0 Without this patch obviously __builtin_return_address(0) yields func+0x10 instead of the return address of the caller. Note this patch fixes a similar issue for the routines used with dynamic ftrace even though this isn't currently selectable for ARM.

[ARM] 5385/2: unwind: Add unwinding information to exception entry points

2009-02-19T11:27:35Z

This is needed to allow or stop the unwinding at certain points in the kernel like exception entries. Signed-off-by: Catalin Marinas Signed-off-by: Russell King

annotate that [fp, #-4] is the saved lr

ftrace: rename FTRACE to FUNCTION_TRACER

2008-10-20T16:27:03Z

Due to confusion between the ftrace infrastructure and the gcc profiling tracer "ftrace", this patch renames the config options from FTRACE to FUNCTION_TRACER. The other two names that are offspring from FTRACE DYNAMIC_FTRACE and FTRACE_MCOUNT_RECORD will stay the same. This patch was generated mostly by script, and partially by hand.

[ARM] 5227/1: Add the ENDPROC declarations to the .S files

2008-09-01T11:06:34Z

This declaration specifies the "function" type and size for various assembly functions, mainly needed for generating the correct branch instructions in Thumb-2. Signed-off-by: Catalin Marinas Signed-off-by: Russell King

[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach

This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King

ftrace: store mcount address in rec->ip

2008-06-23T20:10:56Z

Record the address of the mcount call-site. Currently all archs except sparc64 record the address of the instruction following the mcount call-site. Some general cleanups are entailed. Storing mcount addresses in rec->ip enables looking them up in the kprobe hash table later on to check if they're kprobe'd.
