Linux v5.4.182-rt72-rc1

From: Tom Zanussi <[email protected]>

Dear RT Folks,

This is the RT stable review cycle of patch 5.4.182-rt72-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 2022-03-20.

To build 5.4.182-rt72-rc1 directly, the following patches should be applied:

https://www.kernel.org/pub/linux/kernel/v5.x/linux-5.4.tar.xz

https://www.kernel.org/pub/linux/kernel/v5.x/patch-5.4.182.xz

https://www.kernel.org/pub/linux/kernel/projects/rt/5.4/patch-5.4.182-rt72-rc1.patch.xz

You can also build from 5.4.182-rt71 by applying the incremental patch:

Enjoy,

v5.4.182-rt72-rc1 stable review patch.
If anyone has any objections, please let me know.

-----------

This fixes an issue in stable-rt release v5.4.182-rt71 where a hunk from the context diff was inadvertently included in a conflict fixup where it shouldn't have been. Remove those lines that don't belong.
