From: Andi Kleen <ak@odo.jf.intel.com>

With the recent tuning the C version of rwlocks is basically the same
performance as the x86 assembler version for uncontended locks (with a
a few cycles near the run-to-run variability). For others it should not
matter anyways.

So remove the assembler code and use the C version like other
architectures.

What benchmark did you used? I would be ok with this when I see data.

A simple benchmark that measured the uncontended performance.
Contended performance is not typically dominated by the actual lock
execution time.

You can see the rdlock is identical, but wrlock is ~6-9 cycles slower.
I originally spent quite some time hunting those 9 cycles, but
then I realized if I run the benchmark many times the run-to-run
variability is higher. So I don't think it's relevant.

With patch:
./obj/testrun.sh ./rwlockbench/micro
rdlock avg 104
wrlock avg 106
rdlock avg 105
wrlock avg 105
rdlock avg 104
wrlock avg 105
rdlock avg 104
...

Without:
./obj-ref/testrun.sh ./rwlockbench/micro
rdlock avg 104
wrlock avg 98
rdlock avg 104
wrlock avg 97
rdlock avg 104
wrlock avg 97
rdlock avg 104
wrlock avg 97
