[akpm]

The patch titled
     high-res timers: next_event calculation fix
has been removed from the -mm tree.  Its filename was
     updated-add-a-framework-to-manage-clock-event-devices-next_event-calculation-fix.patch

This patch was dropped because it is obsolete

------------------------------------------------------
Subject: high-res timers: next_event calculation fix
From: Ingo Molnar <mingo@elte.hu>

Do not set expires_next to KTIME_MAX if a too short timeout is being set -
this can result in the clock events device being shut down completely.

Found via a stresstest on a C3-lapic-plagued laptop that did very short
sleeps.

This bug could explain the 'Synaptics hang' that was reported.
