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.
