Excuse me, Russell, but I sent Nicolas an email prior to doing so asking him
if he had any objections:

	To: Nicolas Pitre <nico@....org>
	cc: dhowells@...hat.com
	Subject: Moving asm-arm/cnt32_to_63.h to include/linux/
	Date: Thu, 31 Jul 2008 16:04:04 +0100

	Hi Nicolas,

	Mind if I move include/asm-arm/cnt32_to_63.h to include/linux/?

	I need to use it for MN10300.

	David

He didn't respond.  Not only that, but I copied Nicolas on the patch to make
the move and the patch to make MN10300 use it when I submitted it to Linus on
the 24th September, so it's not like he didn't have plenty of time.  He
certainly saw that because he joined in the discussion of the second patch.
Furthermore, he could've asked Linus to refuse the patch, or to revert it if
it had already gone in.

I suppose I should've cc'd the ARM list too... but why should it adversely
affect ARM?

David
