This file is a 'special' driver that implements /dev/zero and /dev/mem
among other things.

As such it makes sense for mm to be cc'd on mails and to have some say in
how things are changed there, so add it to the mm misc section.

Uniquely, it provides the 'old way' of obtaining an anonymous mapping -
MAP_PRIVATE of /dev/zero - so is directly tied to memory mapping, therefore
also add it to the memory mapping section.

scripts/get_maintainer.pl copes perfectly fine with files in multiple
sections so everything should work correctly.
