end);
The function
pmap_unwire
()
removes the wired attribute from each of the virtual-to-physical page
mappings within the virtual address range from start
to end of the physical map pmap.
Every valid mapping within that range is required to have the wired
attribute set. Invalid mappings are ignored, since they cannot have the
wired attribute set.
Only the function pmap_enter(9) can be used to set the wired attribute of a virtual-to-physical page mapping.
