Print the PREEMPT/SMP/DEBUG_PAGEALLOC settings during oopses.  The modified
output looks like this:

 Unable to handle kernel paging request at virtual address c4734068
  printing eip:
 c04e58b6
 *pde = 00012067
 Oops: 0000 [#1]
 PREEMPT SMP DEBUG_PAGEALLOC
 CPU:    0

I find it fairly handy.  It sometimes saves an email round-trip when
diagnosing crashes.
