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 in
http://marc.info/?l=linux-kernel&m=123196343531966&w=2 and was acked by
Venki Pallipadi, the author of the original deferrable timer patch.
