Merge git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched
* git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched: sched: mark CONFIG_FAIR_GROUP_SCHED as !EXPERIMENTAL sched: isolate SMP balancing code a bit more sched: reduce balance-tasks overhead sched: make cpu_shares_{show,store}() static sched: clean up some control group code sched: constify sched.h sched: document profile=sleep requiring CONFIG_SCHEDSTATS sched: use show_regs() to improve __schedule_bug() output sched: clean up sched_domain_debug() sched: fix fastcall mismatch in completion APIs sched: fix sched_domain sysctl registration again
