Subject: [PATCH v4 1/5] genirq: export irq_get_percpu_devid_partition to modules
Date: Mon,  5 Jun 2017 16:22:53 +0100	[thread overview]
Message-ID: <1496676177-29356-2-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1496676177-29356-1-git-send-email-will.deacon@arm.com>

Any modular driver using cluster-affine PPIs needs to be able to call
irq_get_percpu_devid_partition so that it can enable the IRQ on the
correct subset of CPUs.

This patch exports the symbol so that it can be called from within a
module.
