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

From: Maxime Ripard <maxime.ripard@...e-electrons.com>

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.
