Message

Add vma_is_initial_stack() and vma_is_initial_heap() helper and use
them to simplify code.

v2:
- add comment for heap helper and remove one more goto cpy_name,
  per David Hildenbrand
- add RB
v2:
- address comments per David Hildenbrand and Christian Göttsche
- fix selinux build

Kefeng Wang (4):
  mm: factor out VMA stack and heap checks
  drm/amdkfd: use vma_is_initial_stack() and vma_is_initial_heap()
  selinux: use vma_is_initial_stack() and vma_is_initial_heap()
  perf/core: use vma_is_initial_stack() and vma_is_initial_heap()
