I got domU performance data now,
Kernel build time is about 1997s on native UP machine
Kernel build time is about 1990s on domU without this patch.
Kernel build time is about 1965s on domU with this patch.

In short, though this patch loses 2% performance on dom0,
it gains >1% performance on domU. 
As we know the performance of domU is more importance than that of dom0.
Seems this patch can be checked in.:-)

Thanks,
Anthony
