Jesper, I noticed that my patch was the only one for CRIS this merge
window (at least looking at linux-next), I hope you're OK with me
sending this directly to Linus. It's just code movement, so I'm
confident it's not going to break anything.

Sorry, _this_ is the one that won't break anything. Previous patch
was incorrect in the defines in arch-v32/swab.h

Please replace #include <asm/types.h> with #include <linux/types.h>
otherwise you will get following 'make headers_check' warnings:
usr/include/asm/swab.h:4: include of <linux/types.h> is preferred
over <asm/types.h>
usr/include/asm/swab.h:14: found __[us]{8,16,32,64} type without

ditto.
If possible, please also fix your other patches which are in queue.

1) I sent this patch bypassing the arch maintainer, so I made it as
simple as possible, just moved the byteorder.h's and changed the
names of the arch-overrides.
2) If you'd care to check, this file is not exported to userspace, so
I can't possible trigger that warning.
3) It's already in Linus' tree, so it's a bit hard for me to change it
now ;-)
