[ Upstream commit cae1d5a2c5a491141faa747e9944ba40ab4ab786 ]

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.

Fixes: 64c349f4ae78 ("mm: add infrastructure for get_user_pages_fast() benchmarking")
