Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc fixes from Benjamin Herrenschmidt:
"Whenever you have a chance between two dives, you might want to
consider pulling my merge branch to pickup a few fixes for 3.8 that
have been accumulating for the last couple of weeks (I was myself
travelling then on vacation).
Nothing major, just a handful of powerpc bug fixes that I consider
worth getting in before 3.8 goes final."
And I'll have everybody know that I'm not diving for several days yet.
Snif.
