Public bug reported:
[Impact]
On some OpenPower systems, RTC does not support set_alarm, and
timer_create(CLOCK_REALTIME_ALARM, ...) will fail with ENOTSUPP instead of
EOPNOTSUPP. This will break some regression testing that expects the later
value.
[Test cases]
Run LTP syscalls regression testing, which we do before releasing kernels.
[Regression potential]
This should not break any userspace, as none should be using/expecting ENOTSUPP
for any call. In order to do so, they would have to go out of their way as it's
not defined on libc headers.
