      "message": "mm: more intensive memory corruption debugging\n\nWith CONFIG_DEBUG_PAGEALLOC configured, the CPU will generate an exception\non access (read,write) to an unallocated page, which permits us to catch\ncode which corrupts memory.  However the kernel is trying to maximise\nmemory usage, hence there are usually few free pages in the system and\nbuggy code usually corrupts some crucial data.\n\nThis patch changes the buddy allocator to keep more free/protected pages\nand to interlace free/protected and allocated pages to increase the\nprobability of catching corruption.\n\nWhen the kernel is compiled with CONFIG_DEBUG_PAGEALLOC,\ndebug_guardpage_minorder defines the minimum order used by the page\nallocator to grant a request.  The requested size will be returned with\nthe remaining pages used as guard pages.\n\nThe default value of debug_guardpage_minorder is zero: no change from\ncurrent behaviour.\n\n[akpm@linux-foundation.org: tweak documentation, s/flg/flag/]\nSigned-off-by: Stanislaw Gruszka \u003csgruszka@redhat.com\u003e\nCc: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: \"Rafael J.
