[PATCH v2 2/7] irq: Export per-cpu irq allocation and de-allocation functions

From: Gregory CLEMENT
Date: Fri Sep 25 2015 - 12:12:42 EST

From: Maxime Ripard <maxime.ripard@xxxxxxxxxxxxxxxxxx>

Some drivers might use the per-cpu interrupts and still might be built as a
module. Export request_percpu_irq an free_percpu_irq to these user, which
also make it consistent with enable/disable_percpu_irq that were exported.
