Subject[PATCH 06/16] mm/huge_memory: rename mmun_start to haddr in remove_migration_pmd
Date
mmun_start indicates mmu_notifier start address but there's no mmu_notifier
stuff in remove_migration_pmd. This will make it hard to get the meaning of
mmun_start. Rename it to haddr to avoid confusing readers and also imporve
readability.
