It'd be better to coalesce the format fragments

Not an improvement.
Why do you think it's better?

This exceeds 80 columns.

This would be better as:

	struct pcpu_chunk *target_chunks[] = {
		pcpu_first_chunk, pcpu_reserved_chunk, NULL
	};

And perhaps this should be static const

I thought it would be better indent when return operation is fit in there.
but it wouldn't sorry for my mistake.

I couldn't fix 717 line exceed problem.
What can i do?

Sorry for my e-mail was rejected by vger.kernel.org server.
