[PATCH] sched: multilevel sbe sbf
The fundamental problem that Suresh has with balance on exec and fork is that
it only tries to balance the top level domain with the flag set.
This was worked around by removing degenerate domains, but is still a problem
if people want to start using more complex sched-domains, especially
multilevel NUMA that ia64 is already using.
This patch makes balance on fork and exec try balancing over not just the top
most domain with the flag set, but all the way down the domain tree.
