[PATCH 0/3] powerpc/qspinlock: Some tuning updates
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!
