This is my first patch. The patch remove codes which save/restore ar.rsc to/from vcpu->arch.old_rsc when guest doing memory mode switch( visual -> physical or physical->visual). Due to HV is transparent to guest, so there is no need to save/restore ar.rsc by HV and guest kernel will do that while switching memory mode.
