[PATCH] Enable Core 2 Duo Performance Counters in HVM guest
Hi, Keir,
Currently, HVM guests do not have access to performance counters. So it
is not possible to use performance analyzer software such as vtune in
HVM guest to analyze programme performance. Other usage of performance
counters , for example, the NMI watchdog, won''t function either.
This patch will enable performance counters in HVM guest. Currently,
only Core 2 Duo is implemented.

[PATCH 0/10] Integrate msr.h
Hello,
This series of patches integrates msr.h header.
What it really does, is a series of steps to allow us
to get rid of duplicate code between i386 and x86_64 versions
With this done, achieving paravirt for x86_64 gets really easy,
just a couple of extra code.
The first patch was already sent a while ago, but was not yet pushed
to any tree , to my knowledge. So it is sent again. Also,
