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

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

First, thanks Yamahata and Xiantao for their effort on ptc.g virtualization.

This patch is a small fix.

VMM only needs to switch rr0 and pta when emulating ptc.g.
Because VMM only use rr0 and pta to do global purge on other LPs.
VMM doesn't need to switch rr7, it is time consuming operation.

Thanks,
Anthony
