    Subject[Suspend2][ 10/21] [Suspend2] __suspend_message.
    Date
    The guts of the suspend_message routine. This is for highlevel descriptions
    of what we're doing, which are also printk'd if we're logging everything.

    + *
    + * Description: This function is intended to do the same job as printk, but
    + * without normally logging what is printed. The point is to be
    + * able to get debugging info on screen without filling the logs
    + * with "1/534. ^M 2/534^M. 3/534^M"
    + *
    + * It may be called from an interrupt context - can't sleep!
    + *
    + * Arguments: int mask: The debugging section(s) this message belongs to.
    + * int level: The level of verbosity of this message.
    + * int restartline: Whether to output a \r or \n with this line
    + * (\n if we're logging all output).
    + * const char *fmt, ...: Message to be displayed a la printk.
