The series transitions the ppoll, io_getevents, and pselect syscalls to be y2038 safe. This is part of the work proceeding for syscalls for y2038. It is based on the series [1] from Arnd Bergmann. The overview of the series is as below: 1. Refactor sigmask handling logic for the above syscalls. 2. Provide y2038 safe versions of the syscalls for all ABIs.
