Hi Aravind,

question: what's the story with MC?_MISC[IntP], is that bit still there?
Because I don't see it in my BKDGs here.

The background of the story is

https://lkml.org/lkml/2014/10/7/84

There's this thing we did at the time

f227d4306cf3 ("x86, MCE, AMD: Make APIC LVT thresholding interrupt optional")

which, AFAICR, is about some F15h versions having a counter but *not*
generating a thresholding interrupt. Can you confirm that is still
the case and we can have a counter but no interrupt gets generated on
overflow?

Thanks.
