[EARLY RFC][PATCH 0/4] ION per heap devices

[John Stultz]

This is a *very early RFC* (it builds, that's all I'll say :)
but I wanted to share it to get some initial feedback before I
go down the rabit hole of trying to adapt the Android userland
code to get this fully validated.

This patchset tries to implement the per-heap devices for ION.
The main benefit is that it avoids multiplexing heap operations
through the /dev/ion interface, and allows for each heap to have
its own permissions/sepolicy rules.

Feedback would be greatly appreciated!
thanks
