From: lijiazi <jqqlijiazi@xxxxxxxxx>
Subject: mm/page_alloc.c: print reserved_highatomic info
Print nr_reserved_highatomic in show_free_areas, because when alloc_harder
is false, this value will be subtracted from the free_pages in
__zone_watermark_ok. Printing this value can help analyze memory
allocaction failure issues.
