Hey!

I noticed there was some duplicate code under arm/mach-orion5x directory
so I ended up with a patch that uses existing library function present
in kernel code.

I regretfully have to admit that this patch is NOT even compile-tested,
but I hope that it still useful in case it happens to break something...

Päikest,
Priit ;)

I don't think that this does what you think it does...


thanks,
