  "message": "thp: remove PG_buddy\n\nPG_buddy can be converted to _mapcount \u003d\u003d -2.  So the PG_compound_lock can\nbe added to page-\u003eflags without overflowing (because of the sparse section\nbits increasing) with CONFIG_X86_PAE\u003dy and CONFIG_X86_PAT\u003dy.  This also\nhas to move the memory hotplug code from _mapcount to lru.next to avoid\nany risk of clashes.  We can\u0027t use lru.next for PG_buddy removal, but\nmemory hotplug can use lru.next even more easily than the mapcount\ninstead.\n\nSigned-off-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
