 9	  Binder is used in Android for both communication between processes,
10	  and remote method invocation.
11
12	  This means one Android process can call a method/routine in another
13	  Android process, using Binder to identify, invoke and pass arguments
14	  between said processes.

21	  Binderfs is a pseudo-filesystem for the Android Binder IPC driver
22	  which can be mounted per-ipc namespace allowing to run multiple
23	  instances of Android.
24	  Each binderfs mount initially only contains a binder-control device.
25	  It can be used to dynamically allocate new binder IPC devices via
26	  ioctls.

33	  Default value for the binder.devices parameter.
34
35	  The binder.devices parameter is a comma-separated list of strings
36	  that specifies the names of the binder device nodes that will be
37	  created. Each binder device has its own context manager, and is
38	  therefore logically separated from the other devices.

44	  This feature allows binder selftest to run.
45
46	  Binder selftest checks the allocation and free of binder buffers
47	  exhaustively with combinations of various buffer sizes and
48	  alignments.

27	  The Binder API has been changed to support both 32 and 64bit
28	  applications in a mixed environment.

30	  Enable this to support an old 32-bit Android user-space (v4.4 and
31	  earlier).

33	  Note that enabling this will break newer Android user-space.
