I already have kconfigdebug-set-debug_mutex-to-off-by-default.patch

OK. That explains why -mm2 bounced back at the end of this graph:

But ... it's still way below what 2.6.15 was. There's another thunk
down between 2.6.16 and 2.6.16-git18, AFAICS.
OK, I futzed with the graphs a bit. -git2 to -git3 definitely drops
off. I think -git6 to git7 does as well, though that's much more
difficult to discern amongst the noise. I'll take a look more.
Andy, if there's any way you could rerun all the -git ones on moe
with the CONFIG_DEBUG_MUTEXES stuff disabled, might be easier to see ...
