181  * Map a physical memory region into the kernel's virtual address space
183  * This function is intended for mapping memory-mapped I/O regions into
185  * linear address representing the base of where the physical region is mapped
200  * A caching mode must be selected. By default, the region is read-only
209  * It is highly discouraged to use this function to map system RAM page

282  * parameter, and any base address for re-mapping purposes must be page-

310  * and the two guard pages surrounding the region.
