Subject: [PATCH v2 0/4] KVM: x86: Fixups and PAE+SME fixes

A few stragglers bundled together to hopefully avoid more messy conflicts.

v2 (relative to the fixup mini-series):
  - Moved SME fixes from "PCID fixup" to its correct location, in "Mark
    PAE roots decrypted".
  - Collected Reviewed/Tested-by tags for MMU_PRESENT+MMIO snafu, though
    I expect they'll get squashed away.
  - Added the PAE patches from the SME shadow paging fixes to avoid
    spreading out the dependencies.

Sean Christopherson (4):
  KVM: x86: Fixup "Get active PCID only when writing a CR3 value"
  KVM: x86/mmu: Exclude the MMU_PRESENT bit from MMIO SPTE's generation
  KVM: x86/mmu: Use '0' as the one and only value for an invalid PAE
    root
  KVM: x86/mmu: Mark the PAE roots as decrypted for shadow paging
