Subject: [GIT PULL] SLAB changes for v2.6.39-rc1

Hi Linus,

Here's SLAB updates for 2.6.39-rc1. The interesting bits are SLUB lockless 
fastpath patches from Christoph which improve performance and updates to 
support bigger 'struct rcu_head' from Lai. I pulled the per-CPU tree to 
slub/lockless which is why some already merged patches show up in the 
pull request.

                         Pekka
