arch/ppc is broken

[Josh Boyer]

Every arch/ppc defconfig I built today failed.  Someone broke it.
Those interested in fixing it might want to see why.  I suspect the

 ppc/powerpc: use kbuild.h instead of defining macros in asm-offsets.c

is responsible, but I have no evidence of that.

On a related note, arch/ppc defconfig doesn't even configure anymore;
common_defconfig was removed, but it is still the default.  What config
should we use as default now?

Josh, I'll look into the build failure now.

I'd be willing to guess that the answer is "nothing".  You're welcome
to use ebony_defconfig but that's just as much unmaintained as the rest
of arch/ppc and only builds when someone doesn't break it.

Masochist ;)

Plain "defconfig" should use _something_.  Something that still exists,
even.

Yeah, that's what I use again now.

That's more often than "never even starts to build" ;-)

Sadist.
