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
Thepmap_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().
