commit 96da4350000973ef9310a10d077d65bbc017f093 upstream.
-- snip --
Minor conflict, keep the altmap check.
-- snip --
The zone type check was a leftover from the cleanup that plumbed altmap through the memory hotplug path, i.e. commit da024512a1fa "mm: pass the vmem_altmap to arch_remove_memory and __remove_pages".
