Dear RT folks!

I'm pleased to announce the v5.9-rc8-rt12 patch set. 

Changes since v5.9-rc8-rt11:

  - The kernel test robot reported a few warnings due to the printk code
    and a compile error in the powerpc architecture.

Known issues
     - It has been pointed out that due to changes to the printk code the
       internal buffer representation changed. This is only an issue if tools
       like `crash' are used to extract the printk buffer from a kernel memory
       image.

The delta patch against v5.9-rc8-rt11 is appended below and can be found here:
 
     https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.9/incr/patch-5.9-rc8-rt11-rt12.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 v5.9-rc8-rt12

The RT patch against v5.9-rc8 can be found here:

    https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.9/older/patch-5.9-rc8-rt12.patch.xz

The split quilt queue is available at:

Just as heads up. I just tried to build for arm64 but PREEMPT_RT
is not available anymore. Looks like ARCH_SUPPORTS_RT is only
available for !KVM.

Thanks,
Daniel

It has been announced in v5.9-rc2-rt1
   https://lore.kernel.org/linux-rt-users/20200824154605.v66t2rsxobt3r5jg@linutronix.de/

and you replied to that mail. That mail contains information why and
what needs to be done to remove that restriction.

D'oh, you have clearly a better memory than me. I forgot about it 
completely. Sorry for the noise.

Thanks,
