The plan is to change the kernel's handling of failures in "init="
command line processing.  We're a bit uncertain about the downstream
effects of this, so we make the new behaviour Kconfigurable in 3.19 and
if that's all OK, remove the Kconfigurability and switch to the new
behaviour in 3.20.  I queued the 3.20 patch at the same time so I
wouldn't forget about it.

Is there some problem with the current mainline 3.19 code?
