+ * - Some hardware uses illegal values as "wildcard" match
+ * values, which non-Linux firmware (like a BIOS) may try
+ * to set up as e.g. "alarm 15 minutes after each hour".
+ * Linux uses only oneshot alarms.
+ *
+ * When we see that here, we deal with it by using values from
+ * a current RTC timestamp for any missing (-1) values. The
+ * RTC driver prevents "periodic alarm" modes.
+ *
+ * But this can be racey, because some fields of the RTC timestamp
+ * may have wrapped in the interval since we read the RTC alarm,
+ * which would lead to us inserting inconsistent values in place
+ * of the -1 fields.
+ *
+ * Reading the alarm and timestamp in the reverse sequence
+ * would have the same race condition, and not solve the issue.
+ *
+ * So, we must first read the RTC timestamp,
+ * then read the RTC alarm value,
+ * and then read a second RTC timestamp.
+ *
+ * If any fields of the second timestamp have changed
+ * when compared with the first timestamp, then we know
+ * our timestamp may be inconsistent with that used by
+ * the low-level rtc_read_alarm_internal() function.
+ *
+ * So, when the two timestamps disagree, we just loop and do
+ * the process again to get a fully consistent set of values.
+ *
+ * This could all instead be done in the lower level driver,
+ * but since more than one lower level RTC implementation needs it,
