[Xen-ia64-devel][PATCH] ptc.g virtualization fix 2

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

When emulating ptc.ga, VMM needs to change pta temporarily,
which cause VHPT is not mapped by TR, then vhpt fault may 
happen inside VMM, it is not correct.
This patch is to fix this issue.
When changing pta, VMM makes VHPT disabled temporarily.
