PATCH 1/1 Fix build error with !CONFIG_PREEMPT_RT

Hey Thomas, Ingo,
Here's a small build fix to get !CONFIG_PREEMPT_RT +
CONFIG_PREEMPT_HARDIRQS to build. Not sure why this change was introduced between 2.6.29-rt and 2.6.31-rt, but this sets it back.

Tested with and without CONFIG_PREEMPT_RT and with and without CONFIG_PREEMPT_HARDIRQS.
