Subject[PATCH RT 00/31] Linux 3.10.70-rt75-rc1

Dear RT Folks,

This is the RT stable review cycle of patch 3.10.70-rt75-rc1.

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 3/16/2015.

Enjoy,

-- Steve


To build 3.10.70-rt75-rc1 directly, the following patches should be applied:

http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.10.tar.xz

http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.10.70.xz

http://www.kernel.org/pub/linux/kernel/projects/rt/3.10/patch-3.10.70-rt75-rc1.patch.xz

You can also build from 3.10.70-rt74 by applying the incremental patch:
