Sherry Yang a455dfd674 FROMLIST: android: binder: Don't get mm from task
(from https://patchwork.kernel.org/patch/9954125/)

Use binder_alloc struct's mm_struct rather than getting
a reference to the mm struct through get_task_mm to
avoid a potential deadlock between lru lock, task lock and
dentry lock, since a thread can be holding the task lock
and the dentry lock while trying to acquire the lru lock.

Test: ran binderLibTest, throughputtest, interfacetest and
mempressure w/lockdep
