Hi all,

After merging the header_cleanup tree, today's linux-next build (s390
defconfig) failed like this:

arch/s390/kernel/signal.c: In function 'arch_do_signal_or_restart':
arch/s390/kernel/signal.c:491:17: error: implicit declaration of function 'rseq_signal_deliver' [-Werror=implicit-function-declaration]
  491 |                 rseq_signal_deliver(&ksig, regs);
      |                 ^~~~~~~~~~~~~~~~~~~

Presumably caused by commit

  cd1146fc0ad3 ("rseq: Split out rseq.h from sched.h")

I have applied the following patch for today:
