Geert Uytterhoeven 71e0f9c5c3 clk: renesas: r9a06g032: Drop __packed for portability 
[ Upstream commit ceabbf94c3 ]

The R9A06G032 clock driver uses an array of packed structures to reduce
kernel size.  However, this array contains pointers, which are no longer
aligned naturally, and cannot be relocated on PPC64.  Hence when
compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g.
PowerPC allyesconfig), the following warnings are produced:

    WARNING: 136 bad relocations
    c000000000616be3 R_PPC64_UADDR64   .rodata+0x00000000000cf338
    c000000000616bfe R_PPC64_UADDR64   .rodata+0x00000000000cf370
    ...

Fix this by dropping the __packed attribute from the r9a06g032_clkdesc
definition, trading a small size increase for portability.

This increases the 156-entry clock table by 1 byte per entry, but due to
the compiler generating more efficient code for unpacked accesses, the
net size increase is only 76 bytes (gcc 9.3.0 on arm32).

README 

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.
