y2038: more syscalls and cleanups
This concludes the main part of the system call rework for 64-bit time_t,
which has spread over most of year 2018, the last six system calls being
As before, nothing changes for 64-bit architectures, while 32-bit
architectures gain another entry point that differs only in the layout
of the timespec structure. Hopefully in the next release we can wire up
all 22 of those system calls on all 32-bit architectures, which gives
us a baseline version for glibc to start using them.
This does not include the clock_adjtime, getrusage/waitid, and
getitimer/setitimer system calls. I still plan to have new versions
of those as well, but they are not required for correct operation of
the C library since they can be emulated using the old 32-bit time_t
based system calls.
Aside from the system calls, there are also a few cleanups here,
removing old kernel internal interfaces that have become unused after
all references got removed. The arch/sh cleanups are part of this,
there were posted several times over the past year without a reaction
from the maintainers, while the corresponding changes made it into all

timekeeping: remove obsolete time accessors
There are no more remaining users of these deprecated wrappers, so
let's remove them before new users have a chance to make it in.
See Documentation/core-api/timekeeping.rst for replacements when
porting old drivers that contain calls to this function.
