Subject: [PATCH v6 1/7] genirq: export irq_get_percpu_devid_partition to modules
Date: Thu, 12 Oct 2017 13:30:32 +0100 [thread overview]
Message-ID: <1507811438-2267-2-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1507811438-2267-1-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.
