mm: SLAB Out-of-memory diagnostics
Following the example at mm/slub.c, add out-of-memory diagnostics to the
SLAB allocator to help on debugging certain OOM conditions.
An example print out looks like this:
<snip page allocator out-of-memory message>

cache: bio-0, object size: 192, order: 0
node 0: slabs: 3/3, objs: 60/60, free: 0
