[PATCH] Have split-include take another argument

[Tom Rini <trini@kernel.crashing.org>]

Hello.  The following patch makes split-include take another argument,
which is the prefix of what is being split up.  This is needed since I'm
working on a system which will allow for various params in the kernel to
be tweaked at compile-time, without offering numerous CONFIG options
(see http://marc.theaimsgroup.com/?l=linux-kernel&m=103669658505842&w=2).
I'm sending this out for two reasons.  First, does anyone see any
problems with the patch itself?  Second, Kai, would you be willing to
apply this patch now, or would should I wait until the system is ready?
