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.

+/* __suspend_message.
+ *
+ * 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.
