[18/18] SLUB: Use fallback for table of callers/freers of a slab cache

[Christoph Lameter <clameter@sgi.com>]

The caller table can get quite large if there are many call sites for a
particular slab. Add GFP_FALLBACK allows falling back to vmalloc in case
the caller table gets too big and memory is fragmented. Currently we
would fail the operation.
