Subject: [-next] strace tests fail because of "y2038: socket: Add
 compat_sys_recvmmsg_time64"

Hi Arnd,

in linux-next as of today 16 strace self tests fail on s390. I could
bisect this to b136972b063b ("y2038: socket: Add compat_sys_recvmmsg_time64").

The following tests fail:

mmsg.gen.test
clock.gen.test
regex.gen.test
sched.gen.test
trace_fstatfs.gen.test
trace_personality_regex_64.gen.test
trace_fstat.gen.test
trace_personality_32.gen.test
trace_question.gen.test
trace_personality_regex_32.gen.test
trace_personality_64.gen.test
trace_stat.gen.test
trace_statfs.gen.test
trace_lstat.gen.test
trace_stat_like.gen.test
trace_statfs_like.gen.test

If needed the s390 kernel config can be re-created with

make ARCH=s390 performance_defconfig

strace self tests can be reproduced with

> git clone https://gitlab.com/strace/strace.git
> cd strace
> ./bootstrap
> ./configure
> make
> cd tests
> make check
