Thread-topic: [PATCH] Fix context switch to idle domain
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.

Signed-off-by Kevin Tian <kevin.tian@xxxxxxxxx>

Thanks,
Kevin
