- * FUNCTION:    sm_osl_suspend
- *
- * PARAMETERS:  %state: Sleep state to enter. Assumed that caller has filtered
- *              out bogus values, so it's one of S1, S2, S3 or S4
- *
- * RETURN:      ACPI_STATUS, whether or not we successfully entered and
- *              exited sleep.
- *
- * DESCRIPTION:
- * This function is the meat of the sleep routine, as far as the ACPI-CA is
- * concerned.
- *
- * See Chapter 9 of the ACPI 2.0 spec for details concerning the methodology here.
- *
- * It will do the following things:
- * - Call arch-specific routines to save the processor and kernel state
- * - Call acpi_enter_sleep_state to actually go to sleep
- * ....
- * When we wake back up, we will:
- * - Restore the processor and kernel state
- * - Return to the user
- *
- * By having this routine in here, it hides it from every part of the CA,
- * so it can remain OS-independent. The only function that calls this is
- * sm_proc_write_sleep, which gets the sleep state to enter from the user.
