[PATCH 3/6] KVM: x86/mmu: Add MMU-internal header

[Sean Christopherson]

Add mmu/mmu_internal.h to hold declarations and definitions that need
to be shared between various mmu/ files, but should not be used by
anything outside of the MMU.

Begin populating mmu_internal.h with declarations of the helpers used by
page_track.c.
