powerpc/perf: patches for 3.15

[Michael Ellerman]

Hi folks,

This is the series of patches I have in my git tree to send to Ben.

https://github.com/mpe/powerpc-merge

These have all been to the list previously as-is, except for some of Cody's
which I've modified slightly to avoid depending on other peoples' trees.

The patch to fs/sysfs/group.c has already been merged by Greg, but we want to
carry it too so the code works prior to merging with his tree.

cheers
