SLUB: Fix per-cpu merge conflict
The slab tree adds a percpu variable usage case (commit 9dfc6e68bfe6ee452efb1a4e9ca26a9007f2b864 "SLUB: Use this_cpu operations in slub"), but the percpu tree removes the prefixing of percpu variables (commit dd17c8f72993f9461e9c19250e3f155d6d99df22 "percpu: remove per_cpu__ prefix"), thus causing the following compilation error: CC mm/slub.o mm/slub.c: In function ‘alloc_kmem_cache_cpus’: mm/slub.c:2078: error: implicit declaration of function ‘per_cpu_var’ mm/slub.c:2078: warning: assignment makes pointer from integer without a cast make[1]: *** [mm/slub.o] Error 1 Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
