    sys/vm               uma_core.c 
  Log:
  Remove uma_zalloc_arg() hack, which coerced M_WAITOK to M_NOWAIT when
  allocations were made using improper flags in interrupt context.
  Replace with a simple WITNESS warning call.  This restores the
  invariant that M_WAITOK allocations will always succeed or die
  horribly trying, which is relied on by many UMA consumers.
