[Xen-ia64-devel] [PATCH] [Resend]Enable hash vtlb

["Xu, Anthony" <anthony.xu@xxxxxxxxx>]

Hash vTLB is intended to address SMP scalability for large system.

Kernel build on dom0 loses about 2% performance,
While dom0 can support non-contiguous memory, and can address 
Hugetlb issue. Those incur performance degradation.

Kernel build on domU gains about 1% performance.

Signed-off-by: Anthony Xu <anthony.xu@xxxxxxxxx>

Thanks,
-Anthony
