This patchset fixes the migration of sPAPR radix guests.
Changes in v4
-------------
- The earlier approach of keeping the HTAB savevm handlers registered
only for hash guests by explicitly deregistering does leave out a few
corner cases which become ugly/difficult to fix. Hence based on
David Gibson's suggestion, this new approach adds a new
"no HPT" encoding into the migration stream when guest doesn't
allocate HPT.
- There are a few assumptions in HTAB savevm handlers that spapr->htab
will not be set only for KVM guests. This is no longer true with
radix TCG guests. Fix this assumption. These changes enable TCG migration
to work. However guest kernel failures are observed post migration which
need to be fixed separately. This changes could acutally go into
a separate patch.
