Subject: [PATCH] net: mvpp2: use cache_line_size() to get cacheline size
Date: Fri, 1 Apr 2016 17:11:05 +0800	[thread overview]
Message-ID: <1459501865-7033-1-git-send-email-jszhang@marvell.com> (raw)

L1_CACHE_BYTES may not be the real cacheline size, use cache_line_size
to determine the cacheline size in runtime.
