Subject: [PATCH 0/2] x86/microcode/intel: Extend BDW late-loading with platform id and LLC check

The fix further reduces the impact for the BDW model which has to launch
a machine reset in order to run microcode update in BIOS. This point is
important for some vendors without the concern about machine reboot in
order to fix up Spectre v2.
