-Subject: [PATCH 6/7] lib/irq_poll: Declare IRQ_POLL softirq vector as
- ksoftirqd-parking safe
-
-The following warning may appear while setting a CPU down:
-
-	NOHZ tick-stop error: Non-RCU local softirq work is pending, handler #20!!!
-
-The IRQ_POLL_SOFTIRQ vector can be raised during the hotplug cpu_down()
-path after ksoftirqd is parked and before the CPU actually dies. However
-this is handled afterward at the CPUHP_IRQ_POLL_DEAD stage where the
-queue gets migrated.
-
-Hence this warning can be considered spurious and the vector can join
-the "hotplug-safe" list.
