Subject: [PATCH 3.10 02/31] remove extra definitions of U32_MAX
Date: Sun, 26 Apr 2015 15:46:22 +0200	[thread overview]
Message-ID: <20150426134209.360161720@linuxfoundation.org> (raw)
In-Reply-To: <20150426134209.255099785@linuxfoundation.org>

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Elder <alex.elder@linaro.org>

commit 04f9b74e4d96d349de12fdd4e6626af4a9f75e09 upstream.

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