NAME
     pmap_remove, pmap_remove_all, pmap_remove_pages -- remove pages from a physical map

SYNOPSIS
     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/pmap.h>

     void
     pmap_remove(pmap_t pmap, vm_offset_t sva, vm_offset_t eva);

     void
     pmap_remove_all(vm_page_t m);

     void
     pmap_remove_pages(pmap_t pmap);

DESCRIPTION
     The pmap_remove() function removes the range of addresses between sva and eva from the physical map pmap.	If eva is less than sva, then the
     result is undefined.  It is assumed that both sva and eva are page-aligned addresses.

     The pmap_remove_all() removes the physical page m from all physical maps in which it resides, and reflects back the modify bits to the appro-
     priate pager.

     The pmap_remove_pages() function removes all user pages from the physical map pmap.  This function is called when a process exits to run down
     its address space more quickly than would be the case for calling pmap_remove().
