[Qemu-ppc] [RFCv2 0/6] PAPR hash page table resizing

[David Gibson]

This series implements the host / qemu side to allow hash page table
(HPT) resizing for PAPR (pseries machine type) guests.  This is a
proposed extension to the PAPR spec.  It also requires awareness on
the guest side, which I've posted a series for today.

This applies on top of my ppc-for-2.6 branch.

Changes from RFCv1:
  * Limit the guest's HPT to one order larger than we'd usually give them
  * Size initial HPT for initial rather than maximum memory for guests
    that are HPT resize aware

David Gibson (6):
  pseries: Simplify handling of the hash page table fd
  pseries: Move hash page table allocation to reset time
  pseries: Stubs for HPT resizing
  pseries: Implement HPT resizing
  pseries: Enable HPT resizing for 2.6
  pseries: Use smaller default hash page tables when guest can resize
