This series is based on Aneesh's series  "[PATCH -V2 0/5] powerpc: mm: Numa faults support for ppc64"

For this series, I apply the same idea from the previous thread "[PATCH 0/3] optimize for powerpc _PAGE_NUMA"
(for which, I still try to get a machine to show nums)

But for this series, I think that I have a good justification -- the fact of heavy cost when switching context between guest and host,
which is  well known.

If my suppose is correct, will CCing kvm at vger.kernel.org from next version.


Liu Ping Fan (4):
  mm: export numa_migrate_prep()
  powernv: kvm: make _PAGE_NUMA take effect
  powernv: kvm: extend input param for lookup_linux_pte
  powernv: kvm: make the handling of _PAGE_NUMA faster for guest
