Cover letter [PATCH RT 00/13] Linux 3.18.91-rt98-rc1

Dear RT Folks,

This is the RT stable review cycle of patch 3.18.91-rt98-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 1/19/2018.

Enjoy,

-- Steve
