Linus,
	The register_(node|memblk)_driver functions are broken.  Pat Mochel 
recently updated sysfs to make sure that when you register a driver that 
it's associated devclass is already registered.  The way node/memblk 
registration is done now is backwards and causes panic's on NUMA 
systems.  Please apply this patch to fix it.

Cheers!
