[PATCH] slab: don't BUG on duplicated cache
slab presently goes BUG if someone tries to register an already-registered
cache.
But this can happen if the user accidentally loads a module which is already
statically linked into the kernel. Nuking the kernel is rather a harsh
reaction.
Change it into a warning, and just fail the kmem_cache_alloc() attempt. If
the module is well-behaved, the modprobe will fail and all is well.
Notes:
- Swaps the ranking of cache_chain_sem and lock_cpu_hotplug(). Doesn't seem
important.
