IN  PFN_NUMBER PageFrameIndex

Routine Description:

    This procedure maps the specified physical page into the
    PTE within hyper space reserved explicitly for image page
    header mapping.  By reserving an explicit PTE for mapping
    the PTE, page faults can occur while the PTE is mapped within
    hyperspace and no other hyperspace maps will affect this PTE.

    Note that if another thread attempts to map an image at the
    same time, it will be forced into a wait state until the
    header is "unmapped".


    PageFrameIndex - Supplies the physical page number to map.

Return Value:

    Returns the virtual address where the specified physical page was


    Kernel mode.
