Merge tag 'y2038-new-syscalls' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground into timers/2038
Pull y2038 - time64 system calls from Arnd Bergmann: This series finally gets us to the point of having system calls with 64-bit time_t on all architectures, after a long time of incremental preparation patches. There was actually one conversion that I missed during the summer, i.e. Deepa's timex series, which I now updated based the 5.0-rc1 changes and review comments. The following system calls are now added on all 32-bit architectures using the same system call numbers: 403 clock_gettime64 404 clock_settime64 405 clock_adjtime64 406 clock_getres_time64 407 clock_nanosleep_time64 408 timer_gettime64 409 timer_settime64 410 timerfd_gettime64 411 timerfd_settime64 412 utimensat_time64 413 pselect6_time64 414 ppoll_time64 416 io_pgetevents_time64 417 recvmmsg_time64 418 mq_timedsend_time64 419 mq_timedreceiv_time64 420 semtimedop_time64 421 rt_sigtimedwait_time64 422 futex_time64 423 sched_rr_get_interval_time64 Each one of these corresponds directly to an existing system call that includes a 'struct timespec' argument, or a structure containing a timespec or (in case of clock_adjtime) timeval. Not included here are new versions of getitimer/setitimer and getrusage/waitid, which are planned for the future but only needed to make a consistent API rather than for correct operation beyond y2038. These four system calls are based on 'timeval', and it has not been finally decided what the replacement kernel interface will use instead. So far, I have done a lot of build testing across most architectures, which has found a number of bugs. Runtime testing so far included testing LTP on 32-bit ARM with the existing system calls, to ensure we do not regress for existing binaries, and a test with a 32-bit x86 build of LTP against a modified version of the musl C library that has been adapted to the new system call interface [3]. This library can be used for testing on all architectures supported by musl-1.1.21, but it is not how the support is getting integrated into the official musl release. Official musl support is planned but will require more invasive changes to the library.
