Pull x86 microcode loading updates from Borislav Petkov:
"This update contains work started by Maciej to make the microcode
container verification more robust against all kinds of corruption and
also unify verification paths between early and late loading.
The result is a set of verification routines which validate the
microcode blobs before loading it on the CPU. In addition, the code is
a lot more streamlined and unified.
In the process, some of the aspects of patch handling and loading were
simplified.
