Subject: [PATCH 0/2] Clear AMD's microcode cache on load failure

Drop microcode cache when load operation fails to update microcode.

Also make __apply_microcode_amd() return correct error.

Boris Ostrovsky (2):
  x86/microcode/AMD: Fix __apply_microcode_amd()'s return value
  x86/microcode/AMD: Clean the cache if update did not load microcode
