Macros
#define	ARCH_DATA_PAGE_DIRTY   ((uintptr_t)BIT(6))
	Bit indicating the data page, if evicted, will need to be paged out.
#define	ARCH_DATA_PAGE_LOADED   ((uintptr_t)BIT(0))
	Bit indicating that the data page is loaded into a physical page frame.
#define	ARCH_DATA_PAGE_ACCESSED   ((uintptr_t)BIT(5))
	Bit indicating the data page was accessed since the value was last cleared.
#define	ARCH_DATA_PAGE_NOT_MAPPED   ((uintptr_t)BIT(7))
	If ARCH_DATA_PAGE_LOADED is un-set, this will indicate that the page is not mapped at all.
