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
