Hi,

A few updates while going through the powerpc port of the qspinlock.

Patches 1 and 2 are straightforward, while patch 3 can be considered
more of an rfc as I've only tested on a single machine, and there
could be an alternative way if it doesn't end up being nearly a
universal performance win.

Thanks!

  powerpc/spinlock: Define smp_mb__after_spinlock only once
  powerpc/spinlock: Unserialize spin_is_locked
  powerpc/qspinlock: Use generic smp_cond_load_relaxed
