Ashok Raj (12):
  x86/microcode/intel: Prevent printing updated microcode rev multiple
    times
  x86/microcode/intel: Print old and new rev after early microcode
    update
  x86/microcode/intel: Fix a hang if early loading microcode fails
  x86/microcode: Fix microcode_check() compare after a new uCode update
  x86/microcode: Move late-load warning to earlier where kernel taint
    happens
  x86/microcode: Place siblings in NMI loop while update in progress
  x86/mce: Warn of a microcode update is in progress when MCE arrives
  x86/microcode/intel: Add minimum required revision to microcode header
  x86/microcode: Add a generic mechanism to declare support for minrev
  x86/microcode/intel: Drop wbinvd() from microcode loading
  x86/microcode: Display revisions only when update is successful
  x86/microcode/intel: Add ability to update microcode even if rev is
    unchanged
