IMHO topology.h should have proper values that will fit 'standard'
system usage. I'm not sure that the current values (such as 2 in
SD_NODE) is best number or not... And I think it can differ by archs.

If there are no features that will be affected by the changing
default newidle_idx values, then we can fix it in the templates.
It would be a strong reason - I don't like regression :-)


Thanks,
