[PATCH 35/42] KVM: x86: disable paravirt mmu reporting
From: Marcelo Tosatti mtosa...@redhat.com Disable paravirt MMU capability reporting, so that new (or rebooted) guests switch to native operation. Paravirt MMU is a burden to maintain and does not bring significant advantages compared to shadow anymore.
