Subject: BUG_ON or Oops NULL deref ?

I realize this may start a flamewar, but I would like to have your inputs here:

Do we BUG_ON on NULL pointers before dereferencing them, or even more
idiotically, explicitly check the pointers and return an error if they
are invalid, or, can we sanely assume a NULL deref would Oops.

Yes, we had exploits, but can't we trust mmap_min_addr now ?
