137 ZONE_DEVICE chapter139 The `ZONE_DEVICE` facility builds upon `SPARSEMEM_VMEMMAP` to offer141 address ranges. The "device" aspect of `ZONE_DEVICE` relates to the fact144 to keep the memory pinned for active use. `ZONE_DEVICE`, via153 optionally collected into memory blocks, `ZONE_DEVICE` users have a need155 `ZONE_DEVICE` memory is never marked online it is subsequently never163 The users of `ZONE_DEVICE` are:168 * hmm: Extend `ZONE_DEVICE` with `->page_fault()` and `->page_free()`
