Subject: [PATCH 3.10 02/31] remove extra definitions of U32_MAX

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

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

From: Alex Elder <alex.elder@...aro.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.
