2.6.28-stable review patch.  If anyone has any objections, please let us know.

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

From: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com>

commit 8916edef5888c5d8fe283714416a9ca95b4c3431 upstream.

Impact: task stats regression fix

Original getrusage(RUSAGE_THREAD) implementation can return ru_utime and
ru_stime. But commit "f06febc: timers: fix itimer/many thread hang" broke it.

this patch restores it.
