[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[PATCH 0 of 4] Prune outdated/impossible preprocessor symbols, and update VIOAPIC emulation
Patch 1 removes CONFIG_SMP
Patch 2 removes separate smp_{,r,w}mb()s as a result of patch 1
Patch 4 removes __ia64__ defines from the x86 arch tree
Patch 3 is related to patch 4 and changes the VIOAPIC to emulate
version 0x20 as a performance gain. It preceeds Patch 4 so as to be
more clear about the functional change.
