Subject: [Patch Part2 v5 24/33] x86/irq: Kill function apic_set_affinity()
Date: Tue, 14 Apr 2015 10:30:01 +0800 [thread overview]
Message-ID: <1428978610-28986-25-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1428978610-28986-1-git-send-email-jiang.liu@linux.intel.com>
Now there's no user of apic_set_affinity(), so kill it.
Also rename vector_set_affinity() to apic_set_affinity() for consistency.
