[PATCH v5 0/6] powerPC/pSeries use pv-qpsinlock as the default spinlock implemention
From: root <root at ltcalpine2-lp13.aus.stglabs.ibm.com>
change from v4:
BUG FIX. thanks boqun reporting this issue.
struct __qspinlock has different layout in bigendian mahcine.
native_queued_spin_unlock() may write value to a wrong address. now fix it.
change from v3:
a big change in [PATCH v4 4/6] pv-qspinlock: powerpc support pv-qspinlock
no other patch changed.

[PATCH v8 0/6] Implement qspinlock/pv-qspinlock on ppc
Hi All,
this is the fairlock patchset. You can apply them and build successfully.
patches are based on linux-next
qspinlock can avoid waiter starved issue. It has about the same speed in
single-thread and it can be much faster in high contention situations
especially when the spinlock is embedded within the data structure to be
protected.
v7 -> v8:
add one patch to drop a function call
