Alan Cox dd05fa1945 Add a page size field to struct vm_page. Increase the page size field when ... a partially populated reservation becomes fully populated, and decrease this field when a fully populated reservation becomes partially populated. Use this field to simplify the implementation of pmap_enter_object() on amd64, arm, and i386. On all architectures where we support superpages, the cost of creating a superpage mapping is roughly the same as creating a base page mapping. For example, both kinds of mappings entail the creation of a single PTE and PV entry. With this in mind, use the page size field to make the implementation of vm_map_pmap_enter(..., MAP_PREFAULT_PARTIAL) a little smarter. Previously, if MAP_PREFAULT_PARTIAL was specified to vm_map_pmap_enter(), that function would only map base pages. Now, it will create up to 96 base page or superpage mappings.
