  fs/gfs2/rgrp.c:157:23: warning: constant 0xaaaaaaaaaaaaaaaa is so big it is unsigned long long
  fs/gfs2/rgrp.c:158:23: warning: constant 0x5555555555555555 is so big it is long long
  fs/gfs2/rgrp.c:194:20: warning: constant 0x5555555555555555 is so big it is long long
  fs/gfs2/rgrp.c:204:44: warning: constant 0x5555555555555555 is so big it is long long
