Thread-topic:	[Xen-ia64-devel][PATCH] handle speculative vhpt walk

Since processor may support speculative VHPT walk,

The long format VHPT head entry needs to be disabled

before programming it.

We did encounter an issue caused by speculative VHPT walk,
when we run some stress tests on guest linux.

That indicates Montecito supports speculative VHPT walk.
