Some architectures need to initialize SLAB caches to be able
to allocate page tables. They do that from pgtable_cache_init()
so the later should be called earlier now, best is before
vmalloc_init().

Note: Only powerpc, sparc and xtensa use this and only to
call kmem_cache_create() so with a bit of luck it should
just work...
