When running gup_benchmark test the following output states that
the config options is missing.

$ sudo ./gup_benchmark
open: No such file or directory

$ sudo strace -e trace=file ./gup_benchmark 2>&1 | tail -3
openat(AT_FDCWD, "/sys/kernel/debug/gup_benchmark", O_RDWR) = -1 ENOENT
(No such file or directory)
open: No such file or directory
+++ exited with 1 +++

Fix it by adding config option fragment.
