mmu_role represents the role of the root of the page tables. It does not need any extended bits, as those govern only KVM's page table walking; the is_* functions used for page table walking always use the CPU role. ext.valid is not present anymore in the MMU role, but an all-zero MMU role is impossible because the level field is never zero in the MMU role. So just zap the whole mmu_role in order to force invalidation after CPUID is updated. While making this change, which requires touching almost every occurrence of "mmu_role", rename it to "root_role". Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
