[PATCH v4 1/5] genirq: export irq_get_percpu_devid_partition to modules

From: Will Deacon
Date: Mon Jun 05 2017 - 11:23:08 EST


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.
