pmap_mincore — determine if a virtual address is resident in physical memory

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 the mincore(2) system
call.
Name
pmap_mincore — determine if a virtual address is resident in physical memory
Return Values
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.
