Subject: [PATCH RT 00/23] Linux v4.14.170-rt75-rc2

From: Tom Zanussi <zanussi@...nel.org>

Dear RT Folks,

This is the RT stable review cycle of patch 4.14.170-rt75-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 2020-03-05.

To build 4.14.170-rt75-rc2 directly, the following patches should be applied:

  https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.14.tar.xz

  https://www.kernel.org/pub/linux/kernel/v4.x/patch-4.14.170.xz

  https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/patch-4.14.170-rt75-rc2.patch.xz

You can also build from 4.14.170-rt74 by applying the incremental patch:

  https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/incr/patch-4.14.170-rt74-rt75-rc2.patch.xz


Enjoy,
