mm: arch: make in_gate_area take an mm_struct instead of a task_struct

Browse source 
Morally, the question of whether an address lies in a gate vma should be asked
with respect to an mm, not a particular task.  Moreover, dropping the dependency
on task_struct will help make existing and future operations on mm's more
flexible and convenient.
