Subject: [PATCH] cpuidle: remove unused hrtimer_peek_ahead_timers() call

  commit 9a6558371bcd01c2973b7638181db4ccc34eab4f
  Author: Arjan van de Ven <arjan@linux.intel.com>
  Date:   Sun Nov 9 12:45:10 2008 -0800

     regression: disable timer peek-ahead for 2.6.28

     It's showing up as regressions; disabling it very likely just papers
     over an underlying issue, but time is running out for 2.6.28, lets get
     back to this for 2.6.29

 Many years has passed since 2008, so it seems ok to remove whole `#if 0' block.
