Subject: [ANNOUNCE] v6.6-rt12

Dear RT folks!

I'm pleased to announce the v6.6-rt12 patch set. 

Changes since v6.6-rt11:

  - Add an export back which was accidentally removed with PREEMPT_AUTO
    resulting in a compile failure of kcsan_test if compiled as a
    module. 

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-rt11 is appended below and can be found here:
 
     https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.6/incr/patch-6.6-rt11-rt12.patch.xz

You can get this release via the git tree at:

    https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v6.6-rt12
