Comment 4 for bug 1009098

Started an attempt on applying the patches:

http://xenbits.xen.org/hg/xen-unstable.hg/rev/a06e6cdeafe3 -> is already included.

http://xenbits.xen.org/hg/xen-unstable.hg/rev/eae25241d571

Patch above does not apply cleanly and in the area of microcode update there are a few places I would not want to change without more research.

The set of ATS patches also do often not apply cleanly. Right now I somehow applied them but the differences in code have the risk of getting it wrong.
