Dear RT folks!

I'm pleased to announce the v5.10-rc5-rt11 patch set. 

Changes since v5.10-rc5-rt10:

  - The workaround for the IMX clock driver failure has been replaced
    with a another patch which was proposed upstream.

  - Tweak the rtmutex patches to build a allnoconfig with RT enabled.

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 v5.10-rc5-rt10 is appended below and can be found here:
 
     https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.10/incr/patch-5.10-rc5-rt10-rt11.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 v5.10-rc5-rt11
