Gack, I posted the slightly wrong version. This version prevents lumpy
reclaim ever being used. The figures I posted were for a patch where
this condition looked like
if (COMPACTION_BUILD && priority > DEF_PRIORITY - 2)
sc->lumpy_reclaim_mode = LUMPY_MODE_COMPACTION;
else
sc->lumpy_reclaim_mode = LUMPY_MODE_CONTIGRECLAIM;
