Here are some tiny staging driver and documentation fixes for 4.3-rc3.
 
 All of these resolve reported issues that people have found and have
 been in the linux-next tree for a while with no problems.

- add proper arch dependencies as needed
- audit userspace interfaces to make sure they are sane
ion/
- Remove ION_IOC_SYNC: Flushing for devices should be purely a kernel internal
interface on top of dma-buf. flush_for_device needs to be added to dma-buf
first.
- Remove ION_IOC_CUSTOM: Atm used for cache flushing for cpu access in some
vendor trees. Should be replaced with an ioctl on the dma-buf to expose the
begin/end_cpu_access hooks to userspace.
- Clarify the tricks ion plays with explicitly managing coherency behind the
dma api's back (this is absolutely needed for high-perf gpu drivers): Add an
explicit coherency management mode to flush_for_device to be used by drivers
which want to manage caches themselves and which indicates whether cpu caches
need flushing.
- With those removed there's probably no use for ION_IOC_IMPORT anymore either
since ion would just be the central allocator for shared buffers.
- Add dt-binding to expose cma regions as ion heaps, with the rule that any
such cma regions must already be used by some device for dma. I.e. ion only
exposes existing cma regions and doesn't reserve unecessarily memory when
booting a system which doesn't use ion.
