This, 1/9 and later 7/9, are independently good changes to the
current codebase, unlike all the other patches that become only
necessary if/when we want to migrate to timer_settime().

As such, we would prefer to have these "fixes to the current system"
at the beginning of the series before "enhancements to the current
system" patches.

Thanks.
