Merge branch 'kvm-ppc-next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus...

The big feature this time is support for POWER9 using the radix-tree
MMU for host and guest.  This required some changes to arch/powerpc
code, so I talked with Michael Ellerman and he created a topic branch
with this patchset, which I merged into kvm-ppc-next and which Michael
will pull into his tree.  Michael also put in some patches from Nick
Piggin which fix bugs in the interrupt vector code in relocatable
kernels when coming from a KVM guest.

Other notable changes include:

* Add the ability to change the size of the hashed page table,
  from David Gibson.

* XICS (interrupt controller) emulation fixes and improvements,
  from Li Zhong.

* Bug fixes from myself and Thomas Huth.

These patches define some new KVM capabilities and ioctls, but there
should be no conflicts with anything else currently upstream, as far
as I am aware.
