From cbcff8b1c53e458ed4e23877048d7268fd13ab8a Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 28 May 2021 19:07:46 +1000 Subject: [PATCH] KVM: PPC: Book3S HV P9: Allow all P9 processors to enable nested HV 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.
