The GHES records are queued just for printk.  It has no contradiction
with perf based logging.

I think #5 and #7 just some general code that can be used by perf
based recovering too.  Because we are still waiting for perf based
hardware error logging/recovering infrastructure.  I think we can take
#6 and #8 for now and maybe replace them with perf based solution when
that is ready.

BTW: Can you take a look at another patch with following title?

[PATCH] ACPI, APEI, Add APEI _OSC support

https://lkml.org/lkml/2011/5/25/28

This is needed to enable GHES reporting in firmware on some machines.
