y2038: linux: Provide __timerfd_gettime64 implementation
This patch replaces auto generated wrapper (as described in sysdeps/unix/sysv/linux/syscalls.list) for timerfd_gettime with one which adds extra support for reading 64 bit time values on machines with __TIMESIZE != 64. There is no functional change for architectures already supporting 64 bit time ABI. This patch is conceptually identical to timer_gettime conversion already done in sysdeps/unix/sysv/linux/timer_gettime.c. Please refer to corresponding commit message for detailed description of introduced functions and the testing procedure. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> --- Changes for v4: - Update date from 2019 to 2020 Changes for v3: - Add missing libc_hidden_def() Changes for v2: - Remove "Contributed by" from the file header - Remove early check for (fd < 0) in __timerfd_gettime64 as the fd correctness check is already done in Linux kernel - Add single descriptive comment line to provide concise explanation of the code
