The new type is meant to be used as a y2038 safe structure to be used as part of cmsg data. Presently the SO_TIMESTAMP socket option uses struct timeval for timestamps. This is not y2038 safe. Subsequent patches in the series add new y2038 safe socket option to be used in the place of SO_TIMESTAMP_OLD. struct sock_timeval will be used as the timestamp format at that time.
struct sock_timeval also maintains the same layout across 32 bit and 64 bit ABIs.

should these use fixed-width type __u64?
even if all data models define long long as 64-bit, that might be more descriptive.
