Hello!
We are looking at backporting fd258dc4442c ("x86/mce: Add Skylake quirk
for patrol scrub reported errors") to v5.6. When accompanied by these
guys, it passes our usual kernel smoke-testing:
1df73b2131e3 ("x86/mce: Fixup exception only for the correct MCEs")
1de08dccd383 ("x86/mce: Add a struct mce.kflags field")
Could you please let us know if there any non-obvious prerequisites we
should also be backporting?
Thanx, Paul

why do you even need those two?
fd258dc4442c gives you only an Action Optional severity for that
particular error type and the other two patches are for recovery of
errors in the kernel memory range, i.e., for pmem etc., so should be
unrelated.
I mean, it depends on what you want to backport, ofc.
HTH.
