New Revision: 349571
URL: https://svnweb.freebsd.org/changeset/base/349571

Log:
  upgrade the warning printf-s in bus accessors to KASSERT-s, take 2
  
  After this change sys/bus.h includes sys/systm.h when _KERNEL is
  defined.
  This brings back r349459 but with systm.h hidden from userland.
  
  MFC after:	2 weeks
