Noticed by Victor Fusco.

This is for use with slab users that pass a dynamically allocated slab name in
kmem_cache_create, so that before destroying the slab one can retrieve the name
and free its memory.

The patch makes the following function calls available to allocate memory
on a specific node without changing the basic operation of the slab
allocator:
kmem_cache_alloc_node(kmem_cache_t *cachep, unsigned int flags, int node);
kmalloc_node(size_t size, unsigned int flags, int node);
in a similar way to the existing node-blind functions:
kmem_cache_alloc(kmem_cache_t *cachep, unsigned int flags);
kmalloc(size, flags);
kmem_cache_alloc_node was changed to pass flags and the node information
through the existing layers of the slab allocator (which lead to some minor
rearrangements). The functions at the lowest layer (kmem_getpages,
cache_grow) are already node aware. Also __alloc_percpu can call
kmalloc_node now.
Performance measurements (using the pageset localization patch) yields:

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
