Message:

PGM: Added a new page type for the VT-x APIC access page MMIO alias instead of abusing the MMIO2 aliasing. There are important differences, we can safely access the MMIO2 page when aliased and save time doing so, while the alias created by IOMMMIOMapMMIOHCPage must not be accessed outside the VT-x execution AFAIK.
