Martijn Coenen ac4812c5ff binder: Support multiple /dev instances
Add a new module parameter 'devices', that can be
used to specify the names of the binder device
nodes we want to populate in /dev.

Each device node has its own context manager, and
is therefore logically separated from all the other
device nodes.

The config option CONFIG_ANDROID_BINDER_DEVICES can
be used to set the default value of the parameter.

This approach was favored over using IPC namespaces,
mostly because we require a single process to be a
part of multiple binder contexts, which seemed harder
to achieve with namespaces.

---help---
Binder is used in Android for both communication between processes,
and remote method invocation.
This means one Android process can call a method/routine in another
Android process, using Binder to identify, invoke and pass arguments
between said processes.
config ANDROID_BINDER_DEVICES
string "Android Binder devices"

default "binder"
---help---
Default value for the binder.devices parameter.
The binder.devices parameter is a comma-separated list of strings
that specifies the names of the binder device nodes that will be
created. Each binder device has its own context manager, and is
therefore logically separated from the other devices.
config ANDROID_BINDER_IPC_32BIT
bool

---help---
The Binder API has been changed to support both 32 and 64bit
applications in a mixed environment.
Enable this to support an old 32-bit Android user-space (v4.4 and
earlier).
Note that enabling this will break newer Android user-space.
