Subject: irq_work.h: fix warning when CONFIG_IRQ_WORK=n
A randconfig caught repeated compiler warnings when CONFIG_IRQ_WORK=n due
to the definition of a non-inline static function in <linux/irq_work.h>:
include/linux/irq_work.h +40 : warning: 'irq_work_needs_cpu' defined but not used
Make it inline to supress the warning. This is caused by the following
commit:
Commit 00b429591 ("irq_work: Don't stop the tick with pending works")
merged in v3.9-rc1.
