I just had a play with your for-next branch, and noticed a couple of issues
arising from this:

	1. Removing vfpinstr.h leads to a couple of build failures, as it is
	   still included by arch/arm/kvm/coproc.c (for fmrx, which we should
	   continue to provide) and arch/arm/vfp/vfpmodule.c (similarly, but
	   also fmxr).

	2. vfp.h now contains a bunch of dead function declarations (e.g.
	   vfp_double_normaliseround) which should probably be removed. In
	   fact, the inline functions are unused too, so they could also go.
