This thing does need a better changelog though, and maybe a larger
comment with check_asym_packing(), explaining why and what we're doing
and what we're assuming (that lower cpu number also means lower thread
number).
OK, updated patch below...

Of course! :-)

Some CPUs perform better when tasks are run on lower thread numbers.
In the case of POWER7, when higher threads are idled, the core can run
in lower SMT modes and hence perform better.
This creates a new sd flag to prefer lower threads.
Based heavily on patch from Peter Zijlstra.
