Subject: [PATCH v2 0/4] android: binder: fixes for memory allocator change

This patchset resolves a potential deadlock between lru lock, task lock
and dentry lock reported by lockdep. It also fixes the null pointer
dereference in kernel debug message in binder_alloc.c.

Unused vma argument is removed, and binder shrinker is made static.

   android: binder: Don't get mm from task
   android: binder: Fix null ptr dereference in debug msg
   android: binder: Remove unused vma argument
   android: binder: Change binder_shrinker to static

v2: combines the version 1 of two separate patches and reorder
the commits so that the first two can be applied to 4.14.
