Here's batch of slab/slub/slob changes accumulated over the past few months.
The biggest changes are alignment unification from Christoph Lameter and SLUB
debugging improvements from Ben Greear. Also notable is SLAB 'struct
kmem_cache' shrinkage from Eric Dumazet that helps large SMP systems.

Hi Pekka

Could we also merge in 3.1 following "simple enough" patch ?

Thanks

[PATCH] slab: remove one NR_CPUS dependency

Reduce high order allocations in do_tune_cpucache() for some setups.
(NR_CPUS=4096 -> we need 64KB)

Sorry for the delay. I applied the patch and will send it to Linus within few days.
