I wasn't able to build this patchset for arm64, I applied it on tag
next-20190904:

$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -skj$(getconf
_NPROCESSORS_ONLN) headers_install
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -skj$(getconf
_NPROCESSORS_ONLN) -C tools/testing/selftests/clone3

clone3_set_tid.c: In function ‘raw_clone’:
clone3_set_tid.c:22:17: error: ‘__NR_clone3’ undeclared (first use in
this function); did you mean ‘raw_clone’?
return syscall(__NR_clone3, args, sizeof(struct clone_args));
^~~~~~~~~~~

Any idea what I'm doing wrong?

Cheers,
