The vm_page_insert function adds a page to the given object at the given index. The page is added to both the VM page hash table and to the objects list of pages, but the hardware page tables are not updated. In the case of a user page, it will be faulted in when it is accessed. If the page is a kernel page, the caller is expected to handle adding the page to the kernels pmap.
If PG_WRITEABLE is set in the pages flags, OBJ_WRITEABLE and OBJ_MIGHTBEDIRTY are set in the objects flags.
The vm_page_remove function removes the given page from its object, and from the VM page hash table. The page must be busy prior to this call, or the system will panic. The pmap entry for the page is not removed by this function.
