  Modified files:
    sys/alpha/alpha      swtch.s 
  Log:
  alpha_fpstate_save is fairly expensive (critical enter/exit, possibly
  saves 32 registers) to do on every context switch.  This is only required
  for SMP, so only do it there.
  
  We should also look at moving the critical enter/exit out to the callers
