ntp/pps: replace getnstime_raw_and_real with 64-bit version
There is exactly one caller of getnstime_raw_and_real in the kernel, which is the pps_get_ts function. This changes the caller and the implementation to work on timespec64 types rather than timespec, to avoid the time_t overflow on 32-bit architectures. For consistency with the other new functions (ktime_get_seconds, ktime_get_real_*, ...), I'm renaming the function to ktime_get_raw_and_real_ts64. We still need to convert from the internal 64-bit type to 32 bit types in the caller, but this conversion is now pushed out from getnstime_raw_and_real to pps_get_ts. A follow-up patch changes the remaining pps code to completely avoid the conversion. Acked-by: Richard Cochran <richardcochran@gmail.com> Acked-by: David S.
