    Subject[PATCH 3.14 35/64] powerpc: Align TOC to 256 bytes
    Date
    3.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Anton Blanchard <anton@samba.org>

    commit 5e95235ccd5442d4a4fe11ec4eb99ba1b7959368 upstream.

    Recent toolchains force the TOC to be 256 byte aligned. We need
    to enforce this alignment in our linker script, otherwise pointers
    to our TOC variables (__toc_start, __prom_init_toc_start) could
    be incorrect.

    If they are bad, we die a few hundred instructions into boot.
