[git pull request] scheduler updates

Linus, please pull the latest scheduler git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched.git

this includes a regression fix and two minor fixes. The regression was
noticed today by Arjan on the F8-Test1 kernel (which uses .23-rc2): if
his laptop boots from battery then cpu_khz gets mis-detected and
subsequently sched_clock() runs too fast - causing interactivity
problems. This was a pre-existing sched_clock() regression and those
sched_clock() problems are being addressed by Andi's cpufreq sched-clock
patchset, but meanwhile i've fixed the regression by making the
rq->clock logic more robust against such type of sched_clock()
anomalies. (it was already robust against time warps) Arjan tested the
fix and it solved the problem. There's also a small
kernel-address-information-leak fix for the SCHED_DEBUG case noticed by
Arjan and a fix for a SCHED_GROUP_FAIR branch (not enabled upstream, but
still working if enabled manually).
