pmap_zero_page, pmap_zero_area, — zero-fill a page using machine-dependent optimizations
pmap_zero_page_area(vm_page_t m, int off, int size);
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.
This function is required to be implemented for each architecture supported by FreeBSD.
