  x86, microcode, AMD: Rewrite patch application procedure (2012-08-17 14:17:42 +0200)

----------------------------------------------------------------
Per-family patches cache

This patch set adds code for caching all microcode patches which belong
to the current family on which we're running. We look up the patch
needed for each core from the cache at application time instead of
holding a single patch per-system.

Also, a bunch of fixes/cleanups precede the meat in the last 3.

Patchset has been tested on all families which are supported by the
microcode loader ( >= 0x10).
