Hi,
These are some values I just found from thin-air that should
hopefully make ia64 work after the latest sched patches.

Though it did look like there may have been some problems with
the old values, which I tried to fix up too:

- SD_ALLNODES_INIT had .balance_interval set a specific way -
this field is internal to the scheduler and will end up
sitting between min_interval and max_interval and not do what
was intended, so tweak max_interval instead.

- SD_ALLNODES_INIT had SD_BALANCE_EXEC set. The scheduler
doesn't cope _really_ well with doing balance-on-exec over the
top level of a multi-level NUMA setup like this. It will tend
to fill up the first CPUs in each high level group (cluster of
6 nodes) rather than spreading the load on a per-node basis.
This could be improved if we really need it, but for now remove
the flag from the top level.

- Increase SD_NODES_PER_DOMAIN in the low level NUMA domain so we
still push tasks out a reasonable distance. Set SD_BALANCE_FORK
in this domain too.

Not compiled or tested, sorry.
