I see other files under vfp that include this header.
So if we were to implement Bryan's suggestion, I think a separate patch that moves the header and updates all the depdendencies would be more appropriate.
Are you okay with the relative include path for vfpinstr.h in this patch for now or would you want to see an update to move vfpinstr.h to include/asm?.

Thanks,
Sheetal
