The difference is in the scope of the change. When a change is made to a __MAP_MEGA map, the change affects all processes which are currently mapped to the same file-offset range represented by the pages within the provided range.

The first thing it must do is look up the VMA corresponding to the address that was passed - if the passed address was within the kernel's address range, then there is no VMA, and so this search will fail. Like mprotect(), pkey_mprotect() changes the protection on the pages specified by addr and len.
