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 ad-
     dresses.

     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 appropriate
     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().
