3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anton Blanchard <anton@samba.org>
commit 286e4f90a72c0b0621dde0294af6ed4b0baddabb upstream.
p_end is an 8 byte value embedded in the text section. This means it is only 4 byte aligned when it should be 8 byte aligned. Fix this by adding an explicit alignment.
This fixes an issue where POWER7 little endian builds with CONFIG_RELOCATABLE=y fail to boot.
