Geert Uytterhoeven 1091f78287 ARM: shmobile: smp: Enforce shmobile_smp_* alignment
commit 379c590113ce46f605439d4887996c60ab8820cc upstream.

When the addresses of the shmobile_smp_mpidr, shmobile_smp_fn, and
shmobile_smp_arg variables are not multiples of 4 bytes, secondary CPU
bring-up fails:

    smp: Bringing up secondary CPUs ...
    CPU1: failed to come online
    CPU2: failed to come online
    CPU3: failed to come online
    smp: Brought up 1 node, 1 CPU

Fix this by adding the missing alignment directive.

Fixes: 4e960f52fc ("ARM: shmobile: Move shmobile_smp_{mpidr, fn, arg}[] from .text to .bss")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
