This patchset fixes the migration of sPAPR radix guests.

Migration of hash and radix guests individually has been tested on
TCG and KVM (P8 and P9 hosts). Changeover from HPT to RPT and vice versa
via reboot during migration isn't tested yet since it is possible
to test that currently only with TCG and TCG reboot is being fixed.

Changes in v6:
--------------
- Ensure any allocated HPT is free by the target when the source
  doesn't send HPT.

v5: https://lists.gnu.org/archive/html/qemu-devel/2017-06/msg01637.html

Bharata B Rao (2):
  spapr: Add a "no HPT" encoding to HTAB migration stream
  spapr: Fix migration of Radix guests

I've applied these to ppc-for-2.10, because I'm pretty sure they make
things better than they were.  There are some things I'd really like
to see addressed in followup patches, however.
