powerpc: derive COMMAND_LINE_SIZE from asm-generic

The default COMMAND_LINE_SIZE in asm-generic is 512, so the net effect of this change is nil, aside from the cleanup factor. See also commit 2b74b8569.

1.6.3.3

Just to clarify why this is good: There is a patch from Remis to kbuild that can automatically create the trivial wrappers, so we can remove arch/powerpc/include/asm/setup.h from the kernel once that patch is applied.

I was also planning to submit a series to clean up more powerpc in this way headers where applicable, see
http://git.kernel.org/?p=linux/kernel/git/arnd/asm-generic.git;a=shortlog;h=powerpc

The series needs some forward porting to 2.6.31 as well as testing. If you or someone else wants to help with that, please go ahead!

Thanks,

I'd looked at master and next in your tree; I didn't list all the branches and so I'd not noticed powerpc in there as well.

I'll definitely have a look at what is in there.
