Manfred Spraul 97e2bde47f [PATCH] add kmalloc_node, inline cleanup 
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:
