  Log:
  Grab Giant around calls to DEVICE_SUSPEND/RESUME in acpi_SetSleepState().
  If we are resuming non-MPSAFE drivers, they need Giant held for them.
  This may fix some obscure suspend/resume problems.  It has fixed keyrate
  setting problems that were triggered by cardbus (MPSAFE) changing the
  ordering for syscons resume (non-MPSAFE).  Also, add some asserts that
  Giant is held in our suspend/resume and shutdown methods.
