Linus,
	This series of patches creates a directory-based Topology in sysfs 
(driverfs).  This includes the per-node meminfo patch you wanted, as 
well as UP/SMP/NUMA topology.
	There were discussions between myself, Andrew, Rusty, and Patrick, and 
these are what we agreed on.

(1/5) Core sysfs Topology:
	This patch creates the generic structures that are (will be)
	embedded in the per-arch structures.  Also creates calls to
	register these generic structures (CPUs, MemBlks, & Nodes).

	Note that without arch-specific structures in which to embed
	these structures, and an arch-specific initialization routine,
	these functions/structures remain unused.

(2/5) i386 sysfs Topology
	This patch creates the i386 specific files/functions/structures
	to implement driverfs Topology.  These structures have the
	generic CPU/MemBlk/Node structures embedded in them.

	This patch also creates the arch-specific initialization routine
	to instantiate the topology.

(3/5) per-node (NUMA) meminfo for sysfs Topology
	This patch adds code to DriverFS Topology to expose per-node
	memory statistics.
	This information is exposed via the nodeX/meminfo file.

	The patch also adds 2 helper functions to gather per-node memory
	info.

(4/5) memblk_online_map
	This patch creates a memblk_online_map, much like
	cpu_online_map.  It also creates the standard helper functions,
	ie: memblk_online(), num_online_memblks(), memblk_set_online(),
	memblk_set_offline().

	This is used by driverFS topology to keep track of which memory
	blocks are in the system and online.

(5/5) node_online_map
	This patch creates a node_online_map, much like cpu_online_map.
	It also creates the standard helper functions, ie:
	node_online(), num_online_nodes(), node_set_online(),
	node_set_offline().

	This is used by driverFS topology to keep track of which Nodes
	are in the system and online.

Cheers!
