Linus, please pull this scheduler+debugging git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched.git
These patches successfully passed a couple of hundred 32-bit and 64-bit
x86 random kernel builds and bootups. (The debug patch is fine IMO -
i'll redo this push if it's questionable.)
Thanks!
Ingo
