Subject[PATCH] KVM: x86: Deplete Paolo's brown paper bag supply by one
From
Fix an inverted check on CR0.PG when computing the cpu_role, the MMU is
direct and all CR4 bits ignored if paging is disabled, not enabled.

Fixes: d73678dc11ec ("KVM: x86/mmu: split cpu_role from mmu_role")
Signed-off-by: Sean Christopherson <seanjc@google.com>

I haven't done much testing on the rest of the MMU role patches, this just
popped up in very, very basic testing ;-) I assume this will be squashed,
hence the snarky shortlog.
