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

[1/6] kselftest/arm64: Correct misleading comments on fp-stress irritators

[2/6] kselftest/arm64: Remove unused ADRs from irritator handlers
      https://git.kernel.org/arm64/c/ffca567fef9c
[4/6] kselftest/arm64: Implement irritators for ZA and ZT
      https://git.kernel.org/arm64/c/d65f27d240bb
[5/6] kselftest/arm64: Provide a SIGUSR1 handler in the kernel mode FP stress test
      https://git.kernel.org/arm64/c/7368debf275a
[6/6] kselftest/arm64: Test signal handler state modification in fp-stress
