[Qemu-ppc] [PATCHv2 0/3] target-ppc: Clean up handling of SDR1 and external HPTs

[David Gibson]

These patches cleans up handling of SDR1 (master page table pointer
register for Power) and related cases with an external (i.e. managed
by qemu or KVM, rather than the guest) hash page table (HPT).

I wouldn't push 1/3 or 2/3 on their own after the soft freeze, except
that they simplify 3/3, which fixes a real regression.

Changes since v1:
  * Split out SREGS getters/putters instead of creating a special one just for 
SDR1

David Gibson (3):
  target-ppc: Split out SREGS get/put functions
  target-ppc: Add helpers for updating a CPU's SDR1 and external HPT
  target-ppc: Eliminate kvmppc_kern_htab global
