the old /proc/acpi/ interfaces with cleaner interfaces in sysfs --
non-ACPI-specific generic ones whenever possible.  This effort
is not complete, but it has been in -mm for a long time and
I believe that it is time to push it upstream to benefit
from broader exposure and testing.

Does it still include completely broken alarm interface? Can't find it
in changelogs, so hopefully not.

No. See discussion on linux-acpi.
David Brownell's RTC driver will provide the new RTC interface in sysfs.
/proc/acpi/alarm will go away when the rest of /proc/acpi goes away.

I guess I should say 'sorry for a flame'. I've seen a discussion
(linux-pm or somewhere), but did not see the decision to drop the
offending patch.

Hi, Pavel,
Both the patches that duplicate "alarm" and "wakeup" attributes in sysfs
are dropped. "alarm" attribute can be replaced by the new RTC driver.
And the "wakeup" attribute are in the wish list now.
You can get more details from the original mail.
