Linus, please pull the latest scheduler fixes git tree from:

this tree got booted up ~10 times on x86. Thanks,

	Ingo

Sanity booted and moderately tested on 64-cpu and 128-cpu Niagara2
systems.

thanks David!

btw., this has the CONFIG_HAVE_UNSTABLE_SCHED_CLOCK changes from Peter 
which should improve things on Niagara2. Note that cpu_clock() still has 
sync overhead - this will simply go away, once we are reasonably sure 
about the current sched_clock() code on x86. Those bits still need more 
testing.
