  Modified files:
    sys/sparc64/sparc64  exception.S swtch.S 
  Log:
  Add support for saving and restoring kernel floating point state.  The state
  will be saved if we context switch as a result of an interrupt which occured
  while using the floating point registers in the kernel (which actually can't
  happen right now).  This allows fp disabled traps in the kernel, which
  normally shouldn't happen, so make sure the trapping code is what we expect
  it is.
