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 V0: -Split some patch into small patch. -Modify some patch logs. -Change the methods for converting the syscall function. -Introduce the new function do_sys_settimeofday64().
Baolin Wang (14): 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:Introduce the 64bit methods with timespec64 type for k_clock structure posix-timers:Introduce the 64bit methods for posix-timer.c file 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 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 type
