From: Ben Hutchings <ben.hutchings@codethink.co.uk>

This was done as part of upstream commits fdfb4a99b6ab "8inder:
separate binder allocator structure from binder proc", 19c987241ca1
"binder: separate out binder_alloc functions", and 7a4408c6bd3e
"binder: make sure accesses to proc/thread are safe".  However, those
commits made lots of other changes that are not suitable for stable.
