Paolo (or Radim), Please do a pull from my kvm-ppc-next branch to get a PPC KVM update for 4.11. 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. Thanks, Paul. The following changes since commit a17f32270af1e1054bbc8858b0f27226a2c859ba: kvm: x86: Expose Intel VPOPCNTDQ feature to guest (2017-01-17 17:55:18 +0100) are available in the git repository at:
