PVOID MiMapImageHeaderInHyperSpace( 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". Arguments: PageFrameIndex - Supplies the physical page number to map. Return Value: Returns the virtual address where the specified physical page was mapped. Environment: Kernel mode.
