Dear RT folks!

I'm pleased to announce the v6.6-rt15 patch set. 

Changes since v6.6-rt14:

  - The printk update in v6.6-rt13 led to boot failures on 32bit
    platforms. This has been reported by Francesco Dolcini and the
    kernel test robot.

Known issues
     Pierre Gondois reported crashes on ARM64 together with "rtla timerlat
     hist" as trigger. It is not yet understood. The report is at
	https://lore.kernel.org/70c08728-3d4f-47a6-8a3e-114e4877d120@arm.com

The delta patch against v6.6-rt14 is appended below and can be found here:
