+Subject: conditionally define U32_MAX
+
+From: Alex Elder <alex.elder@linaro.org>
+
+commit 77719536dc00f8fd8f5abe6dadbde5331c37f996 upstream.
+
+The symbol U32_MAX is defined in several spots. Change these
+definitions to be conditional. This is in preparation for the next
+patch, which centralizes the definition in <linux/kernel.h>.

+Subject: remove extra definitions of U32_MAX
+
+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.
