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 V1:
-Split some patch into small patch.
-Change the methods for converting the syscall and add some default function for new 64bit methods for syscall function.
-Introduce the new function do_sys_settimeofday64() and move do_sys_settimeofday() function to head file.
-Modify the EXPORT_SYMPOL issue.
-Add new 64bit methods in cputime_nsecs.h file.
-Modify some patch logs.
