[PATCH v7 26/32] KVM: PPC: Book3S HV P9: Allow all P9 processors to enable nested HV

From: Nicholas Piggin <npiggin@gmail.com>
Date: 2021-05-28 09:20:18
Subsystem: kernel virtual machine for powerpc (kvm/powerpc), linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

All radix guests go via the P9 path now, so there is no need to limit
nested HV to processors that support "mixed mode" MMU. Remove the
restriction.
