From: Borislav Petkov <b...@suse.de>
Hi Ingo,
here's the reworked RAS queue. 1-8 are the ones which Tony already sent
you. They, esp. 5/13 and the ones leading up to it deal with printk'ing
from #MC context. We're basically switching to lockless gen_pool for
that.
Patch 9 is a fix for correctable errors polling (CMCI) where the CMCI
interrupt doesn't get reenabled. This has been this way since 3.15 thus
the stable tag. You might want to queue it to x86/urgent, if possible.
The rest is small cleanups and moving the MCE injector to arch/x86/ras/.
This will be even more useful later when we start cleaning up the error
decoding paths and need a quick way to inject errors.
Please queue for 4.3.
Thanks.
