MMG$ALLOC_PFN_ALGND	MMG$ALLOC_PFN_ALGND_64	MMG$ALLOC_PFN_ALGND_64 should not be called directly. Instead, use the ALLOCPFN macro. Note that 64-bit virtual addresses are required to access PFN database entries.
MMG$ALLOC_ZERO_ALGND	MMG$ALLOC_ZERO_ALGND_64	MMG$ALLOC_ZERO_ALGND_64 should not be called directly. Instead, use the ALLOC_ZERO_PFN macro. Note that 64-bit virtual addresses are required to access PFN database entries.
MMG$CREPAG	MMG$CREPAG_64 MMG_STD$CREPAG_64	Accepts 64-bit addresses and has 3 new inputs: RDE (R12), pagefile_cache (R13) mmg_flags (R14). See mmg_routines.h for STD interface.

MMG_STD$DECPTREF_PFNDB accepts as input a 64-bit virtual address of a PFN database entry for a page table, the reference count of which is to be decremented. MMG_STD$DECPTREF_GPT, accepts as input a 64-bit virtual address of a global page table entry, which lies within a certain global page table page, of which a reference count must be decremented.
