| H A D | irq_work.c | 471ba0e6 Tue Apr 09 04:34:03 CDT 2019 Nicholas Piggin <npiggin@gmail.com> irq_work: Do not raise an IPI when queueing work on the local CPU
The QEMU PowerPC/PSeries machine model was not expecting a self-IPI,
and it may be a bit surprising thing to do, so have irq_work_queue_on
do local queueing when target is the current CPU.
