Linux 3.18.36-rt38-rc2

[Steven Rostedt]

Dear RT Folks,

This is the RT stable review cycle of patch 3.18.36-rt38-rc2.

Please scream at me if I messed something up. Please test the patches too.

The -rc release will be uploaded to kernel.org and will be deleted when
the final release is out. This is just a review release (or release candidate).

The pre-releases will not be pushed to the git repository, only the
final release is.

If all goes well, this patch will be converted to the next main release
on 7/14/2016.

Only difference from v1 is the removal of "ARM: imx: always use TWD on
IMX6Q"

Enjoy,

-- Steve
