  Remove the dummy IPI messaging routines for UP builds and properly
  conditionalize the use of IPI messages in various core kernel modules.
  Change the callback from func(arg, frameptr) to func(arg1, arg2, frameptr),
  where the new argument (arg2) is an integer supplied by the originator.
  Create wrappers for simpler versions of the callback: func(arg1), and
  func(arg1, arg2) (for the moment we presume that GCC will generate code
  for the full-sized three-argument callback which is compatible with one
  and two-argument function pointers).
  This extension to the IPI messaging code is needed to properly implement
  MP-safe tsleep/wakeup code.  Although the extra argument is superfluous in
  most cases, the overhead of doing an IPI is such that there should be no
  noticeable impact on performance.
