  Modified files:
    sys/kern             subr_param.c sys_pipe.c 
    sys/sys              pipe.h 
    sys/vm               vm_init.c vm_kern.c vm_kern.h 
  More pipe changes:
  From alc:
  Move pageable pipe memory to a seperate kernel submap to avoid awkward
  vm map interlocking issues.  (Bad explanation provided by me.)
  From me:
  Rework pipespace accounting code to handle this new layout, and adjust
  our default values to account for the fact that we now have a solid
  limit on allocations.
  Also, remove the "maxpipes" limit, as it no longer has a purpose.
  (The limit on kva usage solves the problem of having two many pipes.)
