[Xen-devel] RE: [patch 0/3]Enable CMCI (Corrected Machine Check Error Interrupt) for Intel CPUs

["Ke, Liping" <liping.ke@xxxxxxxxx>]

Hi, Keir

Thanks a lot for the clean-up and format refine! I will pay more attention to 
this too.And also I tested on the related platform. It's fine.

As for moving *cmci_owner_set* out of stopmachine_run is basically ok for us. 
Just one thing:  
CMCI might happen and lost during the very small window (old owner is cleared 
while new owner is not set). In order to make sure that CMCI could be triggered 
an on the new owner, we need to clear MSR Bank(i) status register [Corrected 
Error Counter] field ( We normally do this @ CMCI interrupt handler, according 
to spec, if the counter is not cleared, CMCI will not be triggered any more).
I made a small patch for it in the attachment. How do you think?

Thanks a lot!
Criping

I checked in the patches as c/s 18938 and then cleaned up significantly as
c/s 18939. Let me know if this stops things working for you. Notice I
deleted more than I added. ;-)
