This is a known issue (at least by me! ;) ).
You have 2 choices:
- either you disable CONFIG_ARM_APPENDED_DTB
- or you appliy the patch "ARM: zImage: Convert 32bits memory size
 and address from ATAG to 64bits DTB"
see https://patchwork.kernel.org/patch/2566771/

This patch have been applied by Russell King in his git tree, and I hope
he will push it soon to Linus for the 3.10-rc2.

By the way I also sent an other fix for led and gpio button:
