/**
 * Maps previously allocated physical memory pages at a specified address in an Address Windowing Extensions (AWE) region.

 * \param VirtualAddress A pointer to the starting address of the region of memory to remap. The value of VirtualAddress must be within the address range that the VirtualAlloc function returns when the Address Windowing Extensions (AWE) region is allocated.
 * \param NumberOfPages The size of the physical memory and virtual address space for which to establish translations, in pages.
 * \param UserPfnArray A pointer to an array of physical page frame numbers.
 * \return NTSTATUS Successful or errant status.
