Subject: [PATCH 081/118] ARM: omap3: cpuidle: enable time keeping

3.5.7.12 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Daniel Lezcano <daniel.lezcano@...aro.org>

commit 0d97558901c446a989de202a5d9ae94ec53644e5 upstream.

The TIME_VALID flag is specified for the different states but
the time residency computation is not done, no tk flag, no time
computation in the idle function.

Set the en_core_tk_irqen flag to activate it.
