Subject: [Patch Part2 v4 11/33] irq_remapping/amd: Clean up unsued code
Date: Tue, 20 Jan 2015 13:51:31 +0800	[thread overview]
Message-ID: <1421733113-15704-12-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1421733113-15704-1-git-send-email-jiang.liu@linux.intel.com>

Now we have converted to hierarchy irqdomain, so clean up unused code.
