This patch series changes the 32-bit time types (timespec/itimerspec) to
the 64-bit types (timespec64/itimerspec64), since 32-bit time types will
break in the year 2038.

This patch series introduces new methods with timespec64/itimerspec64 type,
and removes the old ones with timespec/itimerspec type for posix_clock_operations
and k_clock structure.

Baolin Wang (25):
  time:Introduce struct itimerspec64
  timekeeping:Introduce the current_kernel_time64()
  hrtimer:Introduce hrtimer_get_res64()
  security: Introduce security_settime64()
  time:Introduce the do_sys_settimeofday64()
  posix-timers:Introduce {get,put}_timespec/{get,put}_itimerspec
  posix-timers: Split up timer_gettime()/timer_settime()/clock_settime()/
    clock_gettime()/clock_getres().
  posix-timers: Convert timer_gettime()/timer_settime()/clock_settime()/
    clock_gettime()/clock_getres() to timespec64/itimerspec64.
  mmtimer:Convert to timespec64/itimerspec64
  alarmtimer:Convert to timespec64/itimerspec64
  posix-clock:Convert to timespec64/itimerspec64
  time:Introduce timespec64_to_jiffies()/jiffies_to_timespec64()
  cputime:Introduce cputime_to_timespec64()/timespec64_to_cputime()
  posix-cpu-timers:Convert to timespec64/itimerspec64
  k_clock:Remove timespec/itimerspec
