We should check it fits and if doesn't return an error rather than pretending all was fine.
What kind of error to return in the case it does not fit - ENOEXEC (Exec format error) ?
That one is a bit obscure.
I'd go with either -ERANGE I think as we are reflecting that the clamp to 32 bit
is not representable.
Thanks for hint. Later I've found -ERANGE also and used it in my next patch versions.
