[PATCH 00/21] powerpc/gamecube: make W=1 compilation errors free

[Mathieu Malaterre]

I started working on warnings treated as error on ppc32. As a first step,
here is a set of patches to make gamecube error free when using W=1:

$ make ARCH=powerpc gamecube_defconfig
$ make -j8 ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- W=1

Using:

$ powerpc-linux-gnu-gcc --version
powerpc-linux-gnu-gcc (Debian 6.3.0-18) 6.3.0 20170516
