111  * Such memory is guaranteed to never produce a page fault due to page-outs
112  * or copy-on-write once the mapping call has returned. Physical page frames
113  * will be pre-fetched as necessary and pinned.
118  * Region will be unpaged i.e. not mapped into memory
145  * concurrent memory mappings or page-ins take place.
167  * The mapped region is not guaranteed to be physically contiguous in memory.
171  * Pages mapped in this way have write-back cache settings.
173  * The returned virtual memory pointer will be page-aligned. The size
174  * parameter, and any base address for re-mapping purposes must be page-
184  * @param size Size of the memory mapping. This must be page-aligned.
186  * @return The mapped memory location, or NULL if insufficient virtual address
199  * This maps backing-store "location" tokens into Zephyr's address space.
202  * addresses in the mapped range are accessed.
216  * The provided backing-store "location" token must be linearly incrementable

246  * This removes a memory mapping for the provided page-aligned region.
