    Subject[PATCH 3.12 093/144] powerpc: Align p_end
    Date
    3.12-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.
