Merge tag 'kvm-arm-for-4.6-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm
KVM/ARM Fixes for v4.6-rc4
Addresses:
- Wrong indentation in the PMU code from the merge window
- A long-time bug occuring with running ntpd on the host, candidate for stable
- Properly handle (and warn about) the unsupported configuration of running on
systems with less than 40 bits of PA space
- More fixes to the PM and hotplug notifier stuff from the merge window
