The commit ca371c0d7e23 ("memcg: fix page_cgroup fatal error
in FLATMEM") removes call to alloc_bootmem() in the function
so that it can be marked as __meminit to reduce memory usage
when MEMORY_HOTPLUG=n.
Also as new helper function alloc_page_cgroup() is called only
in the function, it should be marked too.

I kept Acked-by's because it seemed like a trivial change, no?
