Pull year 2038 updates from Thomas Gleixner:
 "Another round of changes to make the kernel ready for 2038. After lots
  of preparatory work this is the first set of syscalls which are 2038
  safe:

    403 clock_gettime64
    404 clock_settime64
    405 clock_adjtime64
    406 clock_getres_time64
    407 clock_nanosleep_time64
    408 timer_gettime64
    409 timer_settime64
    410 timerfd_gettime64
    411 timerfd_settime64
    412 utimensat_time64
    413 pselect6_time64
    414 ppoll_time64
    416 io_pgetevents_time64
    417 recvmmsg_time64
    418 mq_timedsend_time64
    419 mq_timedreceiv_time64
    420 semtimedop_time64
    421 rt_sigtimedwait_time64
    422 futex_time64
    423 sched_rr_get_interval_time64

  The syscall numbers are identical all over the architectures"

* 'timers-2038-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits)
  riscv: Use latest system call ABI
  checksyscalls: fix up mq_timedreceive and stat exceptions
  unicore32: Fix __ARCH_WANT_STAT64 definition
  asm-generic: Make time32 syscall numbers optional
  asm-generic: Drop getrlimit and setrlimit syscalls from default list
  32-bit userspace ABI: introduce ARCH_32BIT_OFF_T config option
  compat ABI: use non-compat openat and open_by_handle_at variants
  y2038: add 64-bit time_t syscalls to all 32-bit architectures
  y2038: rename old time and utime syscalls
  y2038: remove struct definition redirects
  y2038: use time32 syscall names on 32-bit
  syscalls: remove obsolete __IGNORE_ macros
  y2038: syscalls: rename y2038 compat syscalls
  x86/x32: use time64 versions of sigtimedwait and recvmmsg
  timex: change syscalls to use struct __kernel_timex
  timex: use __kernel_timex internally
  sparc64: add custom adjtimex/clock_adjtime functions
  time: fix sys_timer_settime prototype
  time: Add struct __kernel_timex
  time: make adjtime compat handling available for 32 bit
