Kernel changes to improve power saving:

Browse source 
+ The timer task now blocks indefinitely if there are no timers active, allowing eTaskConfirmSleepModeStatus to return eNoTasksWaitingTimeout when configUSE_TIMERS is set to 1.
+ The next unblock time is calculated automatically after a task unblocks when waiting for a notification, allowing deep sleep to be entered earlier.
