NAME

       pmap_zero_page, pmap_zero_area, — zero-fill a page using machine-dependent optimizations

SYNOPSIS

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

       void
       pmap_zero_page(vm_page_t m);

       void
       pmap_zero_page_area(vm_page_t m, int off, int size);

DESCRIPTION

       The  pmap_zero_page()  function  zero-fills  an  entire  page using machine-dependent optimizations.  The
       pmap_zero_page_area() function is used to zero-fill an area of a page.   The  range  specified  must  not
       cross a page boundary; it must be contained entirely within a single page.

IMPLEMENTATION NOTES

       This function is required to be implemented for each architecture supported by FreeBSD.
