From 6decf1a33c386d4addc2ed9d269c3868f08c70bb Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 23 Feb 2014 21:40:10 +0000 Subject: [PATCH] sh: Use irq_set_affinity instead of homebrewn code There is no point in having an incomplete copy of irq_set_affinity() for the hotplug irq migration code. Use the core function instead.
