[PATCH v5 0/6] powerPC/pSeries use pv-qpsinlock as the default spinlock implemention
...yield slices to lpar if target cpu is running.
remove unnecessary rmb() in __spin_yield/wake_cpu.
__pv_wait() will check the *ptr == val.
some commit message change
change fome v1:
separate into 6 pathes from one patch
some minor code changes.
I do several tests on pseries IBM,8408-E8E with 32cpus, 64GB memory, kernel 4.6
benchmark test results are below.
