This series seems to work ok with all of SLAB/SLUB/SLOB when also
applying the kobjsize() patch. Without the kobjsize() patch in place,
SLAB and SLUB both work, while SLOB still triggers the >= MAX_ORDER
BUG_ON() for page cache pages. Note that this is still an improvement
over SLUB blowing up, as it was before, even without the kobjsize()

That's probably due to the fact that we use PageSlab for all pages with SLUB and for bigblock pages in SLOB with this patch. Christoph, Matt, any suggestions how to fix the PageSlab check in nommu btw?
