random.h is not needed since commit 6c542ab75714 ("mm/demotion: build
demotion targets based on explicit memory tiers"), all functions moved
into memory-tiers.
nsproxy.h is not needed since commit 228ebcbe634a ("Uninline
find_task_by_xxx set of functions"), no nsproxy, we only call
find_task_by_vpid() now.
hugetlb_cgroup.h is not needed since commit ab5ac90aecf5 ("mm, hugetlb: do
not rely on overcommit limit during migration"), move_hugetlb_state() is
called and it belongs to hugetlb.h, which is already included.
balloon_compaction.h, we have more general movable_operations for non-lru
movable page migration, so it could be dropped.
memremap.h, userfaultfd_k.h and oom.h are introduced for zone device page
migration, but all functions are moved into migrate_device.c, so no needed
anymore too.
