Subject: [PATCH 0/2] mm/page_alloc: Fix couple of unaccepted memory issues

Fix issues with unaccepted memory:

  - try_alloc_pages() gives up too early on machines with unaccepted
    memory;
  - race around zones_with_unaccepted_pages static branch;

Kirill A. Shutemov (2):
  mm/page_alloc: Ensure try_alloc_pages() plays well with unaccepted
    memory
  mm/page_alloc: Fix race condition in unaccepted memory handling
