Dynamic Tick: Enabling longer sleep times on 32-bit

From: Jon Hunter <jon-hunter@ti.com>

This is a resend of the patch series shown here:
http://www.spinics.net/lists/kernel/msg891029.html

This patch series has been updated based on the feedback received and
rebased against the current kernel.

This patch series ensures that the wrapping of the clocksource will not be
missed if the kernel sleeps for longer periods and allows 32-bit machines to
sleep for longer than 2.15 seconds.

Jon Hunter (2):
  Dynamic Tick: Prevent clocksource wrapping during idle
  Dynamic Tick: Allow 32-bit machines to sleep for more than 2.15
    seconds
