[Qemu-devel] [PATCHv2 0/7] Cleanups to Hash Page Table handling

[David Gibson <david@gibson.dropbear.id.au>]

This contains some assorted cleanups and small improvements to the
management of the Hash Page Table for 64-bit ppc systems, and the
"pseries" machine type in particular.

These were devised in the context of getting hash page table resizing
working, but can stand on their own.

I think this is ready to go, if I get an R-b for 4 & 5 / 7 and no
objections to the rest I'll merge into ppc-for-2.6

Changes in v2:
 * Split patch 4/6 into two (4,5/7) with helper for HPT size separate
   from moving the HPT initialization.
 
David Gibson (7):
  target-ppc: Remove unused kvmppc_update_sdr1() stub
  target-ppc: Include missing MMU models for SDR1 in info registers
  pseries: Simplify handling of the hash page table fd
  pseries: Add helper to calculate recommended hash page table size
  pseries: Move hash page table allocation to reset time
  target-ppc: Remove hack for ppc_hash64_load_hpte*() with HV KVM
  target-ppc: Add helpers for updating a CPU's SDR1 and external HPT
