Subject: [PATCH] init: call vfs_caches_init_early() later in the boot
 sequence

From: Pekka Enberg <penberg@...helsinki.fi>

There's no need to call vfs_caches_init_early() before kmem_cache_init(). All
we have to do is make sure we don't attempt to use the bootmem allocator after
we've called mem_init().
