Any opinions on what would be the best thing to do here? Choices appear to be:

1) allow the relative include path of ../vfp/vfpinstr.h
2) move the definitions of fmrx, fmxr from vfp/vfpinstr.h to include/asm/vfp.h
3) move vfp/vfpinstr.h to include/asm
4) other...?

If it helps, I can create a patch for whichever is considered the preferred solution.
