commit 7446e896334cdb5431997dcc30d7ca13768b467d
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>

y2038: Add __USE_TIME_BITS64 support for socket-constants.h
It is only used for !__USE_MISC, the default way uses the kernel
headers. The patch also adds the SO_TIMESTAMP, SO_TIMESTAMPNS, and
SO_TIMESTAMPING which uses new values for 64-bit time_t kernel
interfaces.
The __USE_TIME_BITS64 is not defined internally yet, although the
internal header is used when building the 64-bit stat implementations.
