Subject: [PATCH 3/3] remove extra definitions of U32_MAX
Date: Thu, 26 Dec 2013 09:12:50 -0600
From: Alex Elder <alex.elder@linaro.org>
To: Sage Weil <sage@inktank.com>, David Miller <davem@davemloft.net>,
kuznet@ms2.inr.ac.ru, jmorris@namei.org, yoshfuji@linux-ipv6.org,
kaber@trash.net, Al Viro <viro@ZenIV.linux.org.uk>, jeffm@suse.com,
Steven Rostedt <rostedt@goodmis.org>, Andrew Morton
<akpm@linux-foundation.org>, mst@redhat.com,  Ingo Molnar <mingo@kernel.org>

Now that the definition is centralized in <linux/kernel.h>, the
definitions of U32_MAX (and related) elsewhere in the kernel can
be removed.
