This is correct. I want to set ADDR_NO_RANDOMIZE instead of removing it. even it works with kernel 3.19, but doesn't work with latest kernel. And https://lkml.org/lkml/2015/12/21/340 has been cherry picked back to android kernels < 3.19. I mainly use N5X android device to test, which uses kernel 3.10.
