[PATCH 3/3] slab: avoid __initdata warning (may be a bogus one)

From: Paolo 'Blaisorblade' Giarrusso
Date: Fri Mar 30 2007 - 19:10:08 EST


set_up_list3s is not __init and references initkmem_list3.

Also, kmem_cache_create calls setup_cpu_cache which calls set_up_list3s. The
state machine _may_ prevent the code from accessing this data after freeing
initdata (it makes sure it's used only up to boot), so this warning may be a
false positive.
