Dave 
	I wanted to bring to notice two more issue that I am currently working.
One regarding changes done with kmem_cache to make it NUMA compliant.
'lists' which was earlier pointing to kmem_list3 structure, lists has
been renamed first as nodelists than it is made into an array of pointer
to kmem_list3 structures. So now we have to traverse the whole list
iteratively to get the same information. 
   As a result of these change kmem -s command fails. To accomodate
these changes we need to change the function do_slab_chain_percpu_v2 to
access nodelists iteratively. Still working on it to figure out how I
can accommodate these changes.
Second objectsize in kmem_cache has been changed to object_size and this
is enabled only on selecting config option CONFIG_DEBUG_SLAB in the
kernel.
Thanks
