[Xen-ia64-devel] [PATCH] Fix context switch to idle domain

["Tian, Kevin" <kevin.tian@xxxxxxxxx>]

Don't change ivt table and vhpt table when switching to idle domain, or
else we have to restore region registers too. Actually this change can
also improve performance a bit, since idle domain can inherit most of
prev's environment.

Without this change, we kept seeing vhpt fault when running host SMP
with multiple domains.

Thanks,
Kevin
