Cover letter [PATCH 0/5] x86/microcode: More urgent fixes
From: Borislav Petkov <[email protected]>
Hi guys,
here are fixes for three more issues with the microcode loader. First one is culminating in adding an intel_get_microcode_revision() helper which does the proper steps to get the current microcode revision on an Intel CPU and should be used everywhere instead of opencoding (and forgetting) to do a CPUID(1).
The other two are fixes for 06b8534cb728 ("x86/microcode: Rework microcode loading") which slipped through my testing.
All this is for 4.10 only as it fixes fallout from stuff which went in this merge window.
Please apply,
thanks.
