Merge branch 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86/mm changes from Ingo Molnar:
"The biggest change is new TLB partial flushing code for AMD CPUs.
(The v3.6 kernel had the Intel CPU side code, see commits
e0ba94f14f74..effee4b9b3b.)
There's also various other refinements around the TLB flush code"
