      "message": "mutex: speed up generic mutex implementations\n\n- atomic operations which both modify the variable and return something imply\n  full smp memory barriers before and after the memory operations involved\n  (failing atomic_cmpxchg, atomic_add_unless, etc don\u0027t imply a barrier because\n  they don\u0027t modify the target). See Documentation/atomic_ops.txt.\n  So remove extra barriers and branches.\n\n- All architectures support atomic_cmpxchg. This has no relation to\n  __HAVE_ARCH_CMPXCHG. We can just take the atomic_cmpxchg path unconditionally\n\nThis reduces a simple single threaded fastpath lock+unlock test from 590 cycles\nto 203 cycles on a ppc970 system.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
