Wow! ,from LKML , I have found your patches here :
http://www.spinics.net/lists/linux-acpi/msg34003.html
I check the latest code from
http://lxr.linux.no/linux+v3.2.1/drivers/acpi/apei/ghes.c ,this patch
has been not adopted by upstream.

another question :
for corrected error , hardware can correct it.
but for uncorrected error, especially fatal error , machines need to
be restarted immediately, but for OS ,for different error (NMI
sourcing) ,OS needs to do different ready works before restarting
machine ?

thanks .
