3) void flush_tlb_range(struct vm_area_struct *vma,
unsigned long start, unsigned long end)
call flush_tlb_page (see below) for each entry which may be
modified.

This time we need to remove the PAGE_SIZE sized translation
This is used primarily during fault processing.

This interface is called whenever the protection on
any user PTEs change. This interface provides a notification

Next, we have the cache flushing interfaces. In general, when Linux
