Subject: workaround rtc-related acpi table bugs
From: David Brownell <david-b@xxxxxxxxxxx>
This works around a bug seen in some RTC-related ACPI table entries, and
tweaks related diagnostics to follow the ACPI convention.
The bug prevents misleading boot-time messages: platforms affected by this
bug wrongly report they can support alarms up to one year in the future,
when in fact the longest alarm is just 24 hours. That will surprise anyone
trying to use those extended alarms.
