Yes, APEI.  My mistake.  Too many acronyms for my little mind.

Excellent.  If you could post even the untested code, that would be
helpful. Do you have a timeline for publication?

My patch is fundamentally in response to the fact that your APEI code
is not present yet, and there is a problem seen at customer sites now
(particularly SLES 11, as that's the only "Enterprise"-class distro
version with the AER driver, but also any distro or kernel build that
includes the AER driver).  But without knowing when the rest of the
APEI code will land in mainline, I feel it would be safe to do the
minimum amount of HEST parsing, just enough to know if AER should be
disabled or not.  My patch can be considered "throw-away" code - to be
dropped when your APEI code lands in mainline and the distros.

I agree completely.  But I need a solution in the short-term, both for
mainline and which can be backported, until your code is available.

I'm reworking my patch based on Seto-san's comments, and will repost
soon as linux-next stops crashing on me. :-)

Thanks,
Matt
