Merge branch 'x86-microcode-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86/microcode changes from Ingo Molnar:
"The biggest changes are to AMD microcode patching: add code for
caching all microcode patches which belong to the current family on
which we're running, in the kernel.
We look up the patch needed for each core from the cache at
patch-application time instead of holding a single patch per-system"
