This is with v5.15.81-124-g9269e46bc838.

The backport of commit 9b932aadfc47d seems wrong. The original version introduces
the cpu variable in handle_IPI(). The backport doesn't, and removes old_regs
instead.

Backport:

  void handle_IPI(struct pt_regs *regs)
  {
-       struct pt_regs *old_regs = set_irq_regs(regs);
         unsigned long *pending_ipis = &ipi_data[smp_processor_id()].bits;
         unsigned long *stats = ipi_data[smp_processor_id()].stats;

Original:

void handle_IPI(struct pt_regs *regs)
  {
-       unsigned long *pending_ipis = &ipi_data[smp_processor_id()].bits;
-       unsigned long *stats = ipi_data[smp_processor_id()].stats;
+       unsigned int cpu = smp_processor_id();
+       unsigned long *pending_ipis = &ipi_data[cpu].bits;
+       unsigned long *stats = ipi_data[cpu].stats;

Upstream includes commit 7ecbc648102f which removes the old_regs variable.
That doesn't mean it can be removed in the backport.

Yeah, that looks odd.  I've dropped it from both 5.15 and 6.0 now and
will push out a new -rc with that removed.

thanks for testing!
