This patch set moves internal kernel data in the binder
driver out of mmap regions that is readable by user space.
A shrinker is added to the driver to dynamically manage
the memory used by binder transactions and only free pages
when the system is under memory pressure. This patch set
also adds tests and refactoring in binder allocator.
android: binder: Refactor prev and next buffer into a helper function
android: binder: Add allocator selftest
android: binder: Move buffer out of area shared with user space
android: binder: Add global lru shrinker to binder
android: binder: Add shrinker tracepoints

v3: Fix crash if open is called without followed by mmap.
Also add page usage information in binder stats
