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.
