Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Benjamin Herrenschmidt:
"Here are a few more powerpc bits that I would like in 3.10.
Mostly remaining bolts & screw tightening of power8 support such as
actually exposing the new features via the previously added AT_HWCAP2,
and a few fixes, some of them for problems exposed recently like
irqdomain warnings or sysfs access permission issues, some exposed by
power8 hardware.
The only change outside of arch/powerpc is a small one to irqdomain.c
to allow silent failure to fix a problem on Cell where we get a dozen
WARN_ON's tripping at boot for what is basically a normal case."
