Subject[PATCH 1/2] x86, MCE: Do not taint when handling correctable errors
Date
From: Borislav Petkov <borislav.petkov@amd.com>

Correctable errors are considered something rather normal on modern
hardware these days. Even more importantly, correctable errors mean
exactly that - they've been corrected by the hardware - and there's no
need to taint the kernel since execution hasn't been compromised so far.
