[PATCH 0/4] powerpc: mm_cpumask cleanups and lazy tlb mm

[Nicholas Piggin <npiggin@gmail.com>]

In the process of doing patch 4, I found a few things we could improve
and tighten up with mm_cpumask handling, so added those first. They're
mostly just debugging, no real fixes or dependency on patch 4 there.

Thanks,
Nick
