[PATCH 0/3] x86/ucode: Fixes and improvements to ucode revision handling

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Patch 2 fixes a bug with the Intel revision handling, which is causing
problems on IceLake SDPs.

Patch 3 adds ucode=allow-same to allow for sensible testing of the late
microcode loading path.

Andrew Cooper (3):
  x86/ucode: Break out compare_revisions() from existing infrastructure
  x86/ucode/intel: Fix handling of microcode revision
  x86/ucode: Introduce ucode=allow-same for testing purposes
