[PATCH v2 0/5] KVM: x86: small MMU-adjacent cleanups

[Paolo Bonzini <pbonzini@redhat.com>]

The non-MMU changes/preliminary cleanups from my "separate kvm_mmu"
series; fixed, test, and extracted for inclusion in 7.2.  The rest of
the series can be included later.

The meat here is in patches 2 and 3, which prepare for having a single
copy of the PDPTRs (in vcpu->arch) instead of two (in root_mmu and
nested_mmu).  This is then done in the last patch.

I have redone the nVMX patch now that Sean pointed out that the duplicate
write was a rebase goof.  I kept the nSVM one as is though.

v1->v2:
- rewritten "KVM: nVMX: remove unnecessary code in prepare_vmcs02_rare"
- added "KVM: x86/mmu: move pdptrs out of the MMU"

Thanks,

Paolo
