[PATCH 00/13] x86/microcode: Intel early loader cleanups

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

Hi,

so this is something which got started in the aftermath of a discussion
about some robustifying fixes to the microcode loader by Quentin.
Everyone agrees that current code needs a good rubbing so here's part
one of that. More to come later, let's not overwhelm people with huge
patchsets.

All patches are cleanups and simplifications in an attempt to make the
code more readable and simpler and enable follow-up improvements.

Thanks.

Borislav Petkov (13):
  x86/microcode/intel: Check if microcode was found before applying
  x86/microcode/intel: Do the mc_saved_src NULL check first
  x86/microcode/intel: Get rid of last arg to load_ucode_intel_bsp()
