Merge tag 'kvm-ppc-next-4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc into HEAD
PPC KVM update for 4.20.
The major new feature here is nested HV KVM support. This allows the
HV KVM module to load inside a radix guest on POWER9 and run radix
guests underneath it. These nested guests can run in supervisor mode
and don't require any additional instructions to be emulated, unlike
with PR KVM, and so performance is much better than with PR KVM, and
is very close to the performance of a non-nested guest. A nested
hypervisor (a guest with nested guests) can be migrated to another
host and will bring all its nested guests along with it. A nested
guest can also itself run guests, and so on down to any desired depth
of nesting.
Apart from that there are a series of updates for IOMMU handling from
Alexey Kardashevskiy, a "one VM per core" mode for HV KVM for
security-paranoid applications, and a small fix for PR KVM.
