The .Fn 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. .Sh IMPLEMENTATION NOTES This function is required to be implemented for each architecture supported by .Fx . .Sh SEE ALSO .Xr bzero 3 , .Xr pmap 9 .Sh AUTHORS This manual page was written by .An Bruce M Simpson Aq Mt bms@spc.org .
