Pull another powerpc irq fix from Benjamin Herrenschmidt:
"It looks like my previous fix for the lazy irq masking problem wasn't
quite enough. There was another problem related to performance
monitor interrupts acting as NMIs leaving the flags in an incorrect
state. Here's a fix that finally seems to make perf solid again."
