Linus Torvalds b12a9124ee 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
 
  - 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.
