Right, I'm wondering if AMD can use the same scheme so that abstracting
out the hw-specific accesses (MSR writes, etc) would be enough...

Thanks Tony.

Agreed. Most of this would apply for AMD's threshold interrupts too.

Will come up with a merged patch and move the storm handling to
mce/core.c and just keep the hw-specific accesses separate for
Intel and AMD in their respective files.

Thanks
Smita.
