To be honest this function full of BUG_ONs and it looks fishy to have them there.
Why don't we return EINVAL instead of crashing system?
I completely agree that these assertions should just cause an error-out
rather than trigger a BUG().
Andy did remove bunch of them but there are still few more left overs.
Will have a look at remainder set since most of them were added during
early development and remained there. Thanks Dave/Leon.
