Subject: [PATCH v3 00/22] Convert the posix_clock_operations and k_clock structure to ready for 2038

This patch series changes the 32-bit time type (timespec/itimerspec) to the 64-bit one
(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.

Also introduces some new functions with timespec64/itimerspec64 type, like current_kernel_time64(),
hrtimer_get_res64(), cputime_to_timespec64() and timespec64_to_cputime().

Changes since v2:
     	-Split the syscall conversion patch into small some patches.


Baolin Wang (22):
  linux/time64.h:Introduce the 'struct itimerspec64' for 64bit
  timekeeping:Introduce the current_kernel_time64() function with
    timespec64 type
  time/hrtimer:Introduce hrtimer_get_res64() with timespec64 type for
    getting the timer resolution
  posix-timers:Split out the guts of the syscall and change the
    implementation for timer_gettime
  posix-timers:Convert to the 64bit methods for the timer_gettime
    syscall function
  posix-timers:Split out the guts of the syscall and change the
    implementation for timer_settime
  posix-timers:Convert to the 64bit methods for the timer_settime
    syscall function
  posix-timers:Split out the guts of the syscall and change the
    implementation for clock_settime
  posix-timers:Convert to the 64bit methods for the clock_settime
    syscall function
  posix-timers:Split out the guts of the syscall and change the
    implementation for clock_gettime
  posix-timers:Convert to the 64bit methods for the clock_gettime
    syscall function
  posix-timers:Split out the guts of the syscall and change the
    implementation for clock_getres
  posix-timers:Convert to the 64bit methods for the clock_getres
    syscall function
  time:Introduce the do_sys_settimeofday64() function with timespec64
    type
  time/posix-timers:Convert to the 64bit methods for k_clock callback
    functions
  char/mmtimer:Convert to the 64bit methods for k_clock callback
    function
  time/alarmtimer:Convert to the new 64bit methods for k_clock
    structure
  time/posix-clock:Convert to the 64bit methods for k_clock and
    posix_clock_operations structure
  time/time:Introduce the timespec64_to_jiffies/jiffies_to_timespec64
    function
  cputime:Introduce the cputime_to_timespec64/timespec64_to_cputime
    function
  time/posix-cpu-timers:Convert to the 64bit methods for k_clock
    structure
  k_clock:Remove the 32bit methods with timespec/itimerspec type
