Subject: mm/gup_test: fix ioctl fail for compat task
From: Haibo Li <haibo.li@xxxxxxxxxxxx>
commit 4f572f0074b8be8a70bd150d96a749aa94c8d85f upstream.
When tools/testing/selftests/mm/gup_test.c is compiled as 32bit, then run
on arm64 kernel, it reports "ioctl: Inappropriate ioctl for device".
Fix it by filling compat_ioctl in gup_test_fops
