[PATCH 7/15] sched: Activate build of MN domains

From: Andreas Herrmann
Date: Thu Aug 20 2009 - 09:38:48 EST



I.e. call __build_mn_sched_domain, build corresponding groups
and calculate power.

Note: still missing are changes in various places
to actually detect domain hierarchy and fixup some stuff.
