Merge tag 'ras_updates_for_v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 RAS updates from Borislav Petkov:
- Enable additional logging mode on older Xeons (Tony Luck)
- Pass error records logged by firmware through the MCE decoding chain
to provide human-readable error descriptions instead of raw values
(Smita Koralahalli)
- Some #MC handler fixes (Gabriele Paoloni)
- The usual small fixes and cleanups all over.
