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.
