This is what I have for ARM64 in my PREEMPT_RT queue of what I believe
won't change.

#1 + #2 Were posted before and I don't remember the outcome other than
   to opencode the kfree() in #1.

#3 Replaces a warning and Will said that there is a patch in
   "multi-generational LRU series" which gets rid of it. I'm posting it
   again since it isn't -next.

Applied to arm64 (for-next/sme), thanks!

[1/3] arm64/sve: Delay freeing memory in fpsimd_flush_thread()
      https://git.kernel.org/arm64/c/a1259dd80719
[2/3] arm64/sve: Make kernel FPU protection RT friendly
      https://git.kernel.org/arm64/c/696207d4258b

I appled patch 3 as well to for-next/misc but b4 cannot cope with
applying two subsets of a series.
