This patch provides new __timer_gettime64 explicit 64 bit function for reading status of specified timer. To be more precise - the remaining time and interval set with timer_settime. Moreover, a 32 bit version - __timer_gettime has been refactored to internally use __timer_gettime64. The __timer_gettime is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversion from 64 bit struct __timespec64 to struct timespec. The new __timer_gettime64 syscall available from Linux 5.1+ has been used, when applicable. The original INLINE_SYSCALL() macro has been replaced with INLINE_SYSCALL_CALL() to avoid explicit passing the number of arguments. Build tests: - The code has been tested on x86_64/x86 (native compilation): make PARALLELMFLAGS="-j8" && make check PARALLELMFLAGS="-j8" && \\ make xcheck PARALLELMFLAGS="-j8" - The glibc has been build tested (make PARALLELMFLAGS="-j8") for x86 (i386), x86_64-x32, and armv7 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 - Use of cross-test-ssh.sh for ARM (armv7): make PARALLELMFLAGS="-j8" test-wrapper='./cross-test-ssh.sh root@192.168.7.2' xcheck Linux kernel, headers and minimal kernel version for glibc build test matrix: - Linux v5.1 (with timer_gettime64) and glibc build with v5.1 as minimal kernel version (--enable-kernel="5.1.0") The __ASSUME_TIME64_SYSCALLS flag defined. - Linux v5.1 and default minimal kernel version The __ASSUME_TIME64_SYSCALLS not defined, but kernel supports timer_gettime64 syscall. - Linux v4.19 (no timer_gettime64 support) with default minimal kernel version for contemporary glibc (3.2.0) This kernel doesn't support timer_gettime64 syscall, so the fallback to timer_gettime is tested. Above tests were performed with Y2038 redirection applied as well as without (so the __TIMESIZE != 64 execution path is checked as well). No regressions were observed.
