pmap_mincore -- determine if a virtual address is resident in physical
pmap_mincore(pmap_t pmap, vm_offset_t addr);
The pmap_mincore() function determines if the page at the virtual address
addr in the physical map pmap is resident in physical memory. It is the
machine-dependent interface used by mincore(2) system call.
If the page is resident in physical memory, a mask of flags is returned,
whose meaning is documented in mincore(2); otherwise, `0' is returned.
The pmap must exist and addr must be mapped into the pmap. If any error
occurs, the machine-dependent implementation should return `0'.
