Subject: [PATCH v1 0/2] mm/cma: better error handling and count pages per zone

Two improvements for CMA:
1. When activation of a CMA area fails, hand back all pages to the buddy
2. Count CMA pages per zone and print them in /proc/zoneinfo

David Hildenbrand (2):
  mm/cma: expose all pages to the buddy if activation of an area fails
  mm/page_alloc: count CMA pages per zone and print them in
    /proc/zoneinfo
