[PATCH 2.6.16-mm2 3/4] sched_domain: Use kmalloc_node

[Srivatsa Vaddagiri <vatsa@in.ibm.com>]

The sched group structures used to represent various nodes need to be
allocated from respective nodes (as suggested here also:

	http://uwsg.ucs.indiana.edu/hypermail/linux/kernel/0603.3/0051.html)

Patch below (against 2.6.16-mm2) has been boot tested on a
non-NUMA/4-way SMP machine.
