y2038: remove unused time interfaces
After many small patches, at least some of the deprecated interfaces have no remaining users any more and can be removed: current_kernel_time do_settimeofday get_monotonic_boottime get_monotonic_boottime64 get_monotonic_coarse get_monotonic_coarse64 getrawmonotonic64 ktime_get_real_ts timekeeping_clocktai timespec_trunc timespec_valid_strict time_to_tm For many of the remaining time functions, we are missing one or two patches that failed to make it into 4.19, they will be removed in the following merge window. The replacement functions for the removed interfaces are documented in Documentation/core-api/timekeeping.rst. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
