When a memory error, CPU error, PCIe error, or other type of hardware error
that's covered by RAS occurs, firmware should populate the shared GHES memory
location with the proper GHES structures to notify the OS of the error.
For example, platforms that implement firmware first handling may implement
separate GHES sources for corrected errors and uncorrected errors. If the
error is an uncorrectable error, then the firmware will notify the OS
immediately since the error needs to be handled ASAP. The OS will then be able
to take the appropriate action needed such as offlining a page. If the error
is a corrected error, then the firmware will not interrupt the OS immediately.
Instead, the OS will see and report the error the next time it's GHES timer
expires. The kernel will first parse the GHES structures and report the errors
through the kernel logs and then notify the user space through RAS trace
events. This allows user space applications such as RAS Daemon to see the
errors and report them however the user desires. This patchset extends the
kernel functionality for RAS errors based on updates in the UEFI 2.6 and
ACPI 6.1 specifications.

Thanks, I've pushed this out as:

  git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git for-next/ras-apei

which I'll merge into for-next/core (and therefore linux-next) either the
end of this week or the beginning of next week. Please take a look if you
get a chance.
