Be sure to copy Ard Biesheuvel <ardb@xxxxxxxxxx>, added, on
drivers/firmware/efi/ patches.

Along those lines, drivers/cxl/ developers have an idea of what is
contained in the new CXL protocol error records and why Linux might want
to decode them, others from outside drivers/cxl/ might not. It always
helps to have a small summary of the benefit to end users of the
motivation to apply a patch set.

Sure, will include in my v2.

I notice no updates for the trace events in ghes_do_proc(), is that next
in your queue? That's ok to be a follow-on after v2.

Sorry, if I haven't understood this right. Are you implying about the "handling"
of cxl memory errors in ghes_do_proc() or is it just copying of CPER entries to
tracepoints?

Thanks,
Smita
