y2038: nptl: Convert pthread_{clock|timed}join_np to support 64 bit time
The pthread_clockjoin_np and pthread_timedjoin_np have been converted to support 64 bit time. This change introduces new futex_timed_wait_cancel64 function in ./sysdeps/nptl/futex-internal.h, which uses futex_time64 where possible and tries to replace low-level preprocessor macros from lowlevellock-futex.h The pthread_{timed|clock}join_np only accept absolute time. Moreover, there is no need to check for NULL passed as *abstime pointer as clockwait_tid() always passes struct __timespec64. For systems with __TIMESIZE != 64 && __WORDSIZE == 32: - Conversions between 64 bit time to 32 bit are necessary - Redirection to __pthread_{clock|timed}join_np64 will provide support for 64 bit time Build tests: ./src/scripts/build-many-glibcs.py glibcs Run-time tests: - Run specific tests on ARM/x86 32bit systems (qemu): https://github.com/lmajewski/meta-y2038 and run tests: https://github.com/lmajewski/y2038-tests/commits/master Above tests were performed with Y2038 redirection applied as well as without to test the proper usage of both __pthread_{timed|clock}join_np64 and __pthread_{timed|clock}join_np.
