Andrea Arcangeli ef2b4b95a6 mm: PageBuddy and mapcount robustness ... Change the _mapcount value indicating PageBuddy from -2 to -128 for more robusteness against page_mapcount() undeflows. Use reset_page_mapcount instead of __ClearPageBuddy in bad_page to ignore the previous retval of PageBuddy().
