  • Thread-topic: [PATCH] Clear rse invalid partition before resuming to VTi guest
This patch intends to provide mechanism for clearing  rse invalid
partition before rbs switch to guest. To avoid leaking hypervisor bits
to guest, it is a must to clear registers which are in invalid partition
before leaving hypervisor. 
Tested by full ltp test and Verified by ITP in some cases.
Thanks
