commit a953e4597abd51b74c99e0e3b7074532a60fd031Author: Mike Travis <travis@sgi.com>Date: Mon May 12 21:21:12 2008 +0200
sched: replace MAX_NUMNODES with nr_node_ids in kernel/sched.c
will fix this if it's not in -mm2 already.
The BUG() is simply there to prevent silent corruption. Mike alreadyhas a patch that changes it to a WARN(), but it obviously didn't getthrough (either)...
