New bluesmoke patch available, implements MCE-without-MCA support
Hi everyone,
I have just released a second bluesmoke patch:
ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/bluesmoke-2.4.0-test11-pre5-2.diff
This implements support for MCE on chips which don't support MCA (in addition to enabling MCA for non-Intel chips, like Athlon, which supports MCA.)
I would appreciate it if people who have chips with MCE but no MCA -- this includes older AMD chips and some Cyrix chips at the very least -- would please be so kind and try this out.

Me bad... I accidentally let a one-character typo (missing & sign) in... I have generated a -3 version of this patch.

Hmm, I've looked at the patch and I guess you may try to decode MSR#0 and
MSR#1 for Pentium processors (I may provide an example patch). I believe certain AMD processors support these registers, too. I don't know how other vendors treat MSR#0 and MSR#1 but given they were sufficiently documented since the beginning, they may very well be pretty standard for all of them.
I'll try the patch at my Pentium machine, yet, but it runs so stable I
don't expect an MCE anytime soon. ;-}
