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.
