#1363175 — [PATCH 0/5] mm: make several functions return bool

This series only makes several functions return bool to
improve readability, no other functional changes.

Yaowei Bai (5):
  mm/hugetlb: is_vm_hugetlb_page can be boolean
  mm/memory_hotplug: is_mem_section_removable can be boolean
  mm/vmalloc: is_vmalloc_addr can be boolean
  mm/lru: is_file/active_lru can be boolean
  mm/mempolicy: vma_migratable can be boolean

#1363176 — [PATCH 3/5] mm/vmalloc: is_vmalloc_addr can be boolean

This patch makes is_vmalloc_addr return bool to improve
readability due to this particular function only using either
one or zero as its return value.

No functional change.
