Nicolas Pitre	365bf8ac6f	[ARM] 3311/1: clean up include/asm-arm/mutex.h ... Patch from Nicolas Pitre Since: if (unlikely(__res || __ex_flag)) produces worse code on ARM than: if (unlikely(__res | __ex_flag)) I therefore made it more explicit: __res |= __ex_flag; if (unlikely(__res != 0)) so it is not seen as a typo again. Also made everything static inline rather than macros for better readability (both produce the same code after all). And finally added missing \t from multi-line assembly code.

Nicolas Pitre	823d0f4f67	[PATCH] mutex subsystem, add include/asm-arm/mutex.h ... add the ARM version of mutex.h, which is optimized in assembly for ARMv6, and uses the xchg implementation on pre-ARMv6. Signed-off-by: Ingo Molnar <mingo@elte.hu>	2006-01-09 15:59:18 -08:00
