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 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().
