  SVN rev 191627 on 2009-04-28 11:56:54Z by avg
  
  acpi: do not run resume/backout code when entering S0/S5 states
  
  This change adds (possibly redundant) early check for invalid
  state input parameter (including S0). Handling of S5 request
  is reduced to simply calling shutdown_nice(). As a result
  control flow of acpi_EnterSleepState is somewhat simplified
  and resume/backout half of the function is not executed
  for S5 (soft poweroff) request and invalid state requests.
  
  Note: it seems that shutdown_nice may act as nop when initproc
  is already initialized (to grab pid of 1), but init process is in
  "pre-natal" state.
