Good idea.. But I think its early, the return code could be used for
something useful. I have some additional cleanup patches that I need to
fixup and we could use this for real.

For e.g. early loading failures are now reported by each vendor, if we can
consolidate this, we could do it more at a core level, but I'm worried it
might be too much change right now, and this can wait its turn.

Cheers,
Ashok
