Nick Piggin 0b2fcfdb8b [PATCH] atomic: add_unless cmpxchg optimise ... Without branch hints, the very unlikely chance of the loop repeating due to cmpxchg failure is unrolled with gcc-4 that I have tested. Improve this for architectures with a native cas/cmpxchg. llsc archs should try to implement this natively.
