commit 0f20bba168 ("mm/gup: explicitly define and check internal GUP
flags, disallow FOLL_TOUCH") marked FOLL_TOUCH as a GUP-internal flag.
This causes a warning to fire when running gup_test, for example:
$ ./gup_test -L -r 100 -z
dmesg:
WARNING: CPU: 1 PID: 117 at mm/gup.c:2512 is_valid_gup_args+0x66/0x8c
Therefore, remove the "FOLL_TOUCH" test code from gup_test.c.
