Subject: [PATCH 0/4] KVM: x86: nVMX: Nested PML bug fix and cleanup

Fix for a theoretical bug in nested PML emulation, and additional clean up
of the related code.

Tested by doing a few rounds of intra-VM migration (same L1) of an L2
guest with PML confirmed enabled in L1.

This has a trivial conflict with patch 3 of the MMU files series[*], both
remove function prototypes from mmu.h.
