[PATCH 00/11] KVM: PPC: Book3S HV: Support KVM guests on POWER9

[Paul Mackerras]

This series of patches adds support to HV KVM for running KVM guests
on POWER9 systems.  This allows us to run KVM guests that use HPT
(hashed page table) address translation and know about the POWER9
processor.  With suitable changes to the user-mode driver, this can
also run guests on POWER9 in POWER8 or POWER7 compatibility mode.

For now we require the host to be in HPT mode (not radix).

This series of patches is based on the ppc-kvm topic branch from the
powerpc tree merged with my current kvm-ppc-next tree.

Paul.
