Subject: [PATCH RT 00/22] Linux 4.9.115-rt94-rc1

Hello RT folks!

This patchset brings back many RT-specific fixes that have gone into
subsequent 4.14-rt and 4.16-rt releases.

One of my x86 boxes very intermittently triggers a WARN_ON() on bootup
in migrate_enable(), which I'm still trying to triage.  If you can more
reliably reproduce this, please let me know.

This release candidate will not be pushed to the git tree.

To build 4.9.115-rt94-rc1 directly, the following patches should be applied:

  http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.9.tar.xz

  http://www.kernel.org/pub/linux/kernel/v4.x/patch-4.9.115.xz

  http://www.kernel.org/pub/linux/kernel/projects/rt/4.9/patch-4.9.115-rt94-rc1.patch.xz

If all goes well with testing, this rc will be promoted to an official
release on 8/16/2018.

Please go forth and test!

Thanks,
   Julia
