ARC: syscall for userspace cmpxchg assist

2016-10-24T16:24:26+00:00

Older ARC700 cores (ARC750 specifically) lack instructions to implement atomic r-w-w. This is problematic for userspace libraries such as NPTL which need atomic primitives. So enable them by providing kernel assist. This is costly but really the only sane soluton (othern than tight spinning using the otherwise availiable atomic exchange EX instruciton). Good thing is there are only a few of these cores running Linux out in the wild. This only works on UP systems. Reviewed-by: Colin Ian King Signed-off-by: Vineet Gupta

ARC: remove extraneous KERNEL guards

Verified by doing make headers_install as none of these files are exported to userspace

ARC: ABIv3: fork/vfork wrappers not needed in "no-legacy-syscall" ABI

When switching to clone() only ABI - I missed out pruning the low level asm syscall wrappers Signed-off-by: Vineet Gupta
