    Subjectinlined spinlocks on sparc64

    I deleted the original thread, so I can't reply there. Just a heads up
    on the spinlock inlining on sparc64. I decided to give your patches a
    shot, since one of my IO benchmarks here basically degenerates into a
    spinlock microbenchmark with > 50% time spent there (unlock part,
    according to perf). Some of that is surely caching effects, but still.

    For this particular workload, I get a net improvement of about 3.5% with
    the inlined functions. Not bad.
