Merge branch 'x86/microcode' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 microcode loading update from Peter Anvin:
"This patchset lets us update the CPU microcode very, very early in
initialization if the BIOS fails to do so (never happens, right?)
This is handy for dealing with things like the Atom erratum where we
have to run without PSE because microcode loading happens too late.
As I mentioned in the x86/mm push request it depends on that
infrastructure but it is otherwise a standalone feature."
