    Pull y2038 updates from Arnd Bergmann:
     "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
        - ppoll
        - pselect6
        - io_pgetevents
        - recvmmsg
        - futex
        - rt_sigtimedwait
      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
      other architectures"
