[Xen-ia64-devel][PATCH] Fix a bug related to vcpu migration

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

When destroying domain, only LPs, this domain is running on, do local
TLB purge,
Other LPs may still have TLBs belonging to this domain,
When another domain is created, this may have the same region ID range
with old domain,
and may conflict with old TLB belonging to old domain.
I did observe this scenario, after destroying&creating domain several
times,
Domain crashing happens.
This patch is intended to resolve this issue.
Just before launching a VCPU on a LP, Xen purges local TLB on this LP.

Thanks,
Anthony
