AIU the following commit:
eb631bb5bf5b ("arm64: Support arch_irq_work_raise() via self IPIs")
It seems arm64 hasn't needed that check since
4b3dc9679cf7 ("arm64: force CONFIG_SMP=y and remove redundant
#ifdefs")
Did I get that right?
Indeed. SMP implies being able to IPI, and thus the check has been
irrelevant for some time now.
Thanks,
