From: Dan Williams <dan.j.williams@xxxxxxxxx>
Subject: mm/hotplug: kill is_dev_zone() usage in __remove_pages()
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".
