Subject: [Part 2 v2[cleanup] 0/4] Some additional cleanups in microcode
Date: Sat, 21 Jan 2023 13:35:08 -0800	[thread overview]
Message-ID: <20230121213512.251578-1-ashok.raj@intel.com> (raw)
In-Reply-To: <87y1pygiyf.ffs@tglx>

Hi Thomas and Boris,

This mini series is in response to Thomas's feedback here[1].

I hope this addresses all/most of your concerns you raised in this thread.

Sorry if I missed any, drop more hints and I'll fix them up.

Patch3 needs an AMD change as well. I wasn't confident looking at the
source that was returning the patchid vs reading fromt he real MSR. I'll
check with Boris to confirm before I submit this again.

Now that the other patches are now staged in tip/x86/microcode,
this series applies on top of that.

Cheers,
Ashok
