[PATCH] Allow deferrable timers for intervals tv2-tv5 to be deferred

[Jon Hunter]

In the current kernel implementation only kernel timers for time 
interval tv1 are being deferred. This patch allows any timer that is 
configured as deferrable to be defer regardless of time interval.

This patch was previously discussed on another the thread [1] and Ack'ed 
 by Venki Pallipadi the author of the original deferrable timer patch.

Venki, could you also ack this patch for confirmation?

Cheers
Jon
