[ANNOUNCE] v6.0.5-rt14

[Sebastian Andrzej Siewior]

Dear RT folks!

I'm pleased to announce the v6.0.5-rt14 patch set. 

Changes since v6.0.5-rt13:

  - Replace deprecated API in the Xilinx AXI Ethernet driver so that it
    compiles again. Reported by David Runge.

Known issues
     - Valentin Schneider reported a few splats on ARM64, see
          https://lkml.kernel.org/r/20210810134127.1394269-1-valentin.schneider@arm.com

The delta patch against v6.0.5-rt13 is appended below and can be found here:
 
     https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.0/incr/patch-6.0.5-rt13-rt14.patch.xz

You can get this release via the git tree at:

    git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v6.0.5-rt14

The RT patch against v6.0.5 can be found here:

    https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.0/older/patch-6.0.5-rt14.patch.xz

The split quilt queue is available at:

This is still pending and I don't see it in next. Could someone give me
a ping once this is merged, please?

That is
   d23bc2bc1d634 ("irqchip/gic-v3-its: Postpone LPI pending table freeing and memreserve")
   v5.17-rc1

  3c938cc5cebcb ("gpio: use raw spinlock for gpio chip shadowed data")
  v5.19-rc1

Is someone picking the two up or RT-stable?

This is now merged at:
commit fe40ffdb7656 ("arm_pmu: rework ACPI probing")
commit 6349a2470d07 ("arm_pmu: factor out PMU matching")
commit ad51b5043bb3 ("arm_pmu: acpi: factor out PMU<->CPU association")

If you also judge it is necessary to take:
commit f55a9b59e8f0 ("irqchip/gic-v3-its: Remove cpumask_var_t allocation")

Pierre
