Subject: [PATCH v4 0/5] y2038: Make ppoll, io_pgetevents and pselect y2038 safe

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.

Changes since v3:
* fixed pselect copy+paste error
Changes since v2:
* remove 64BIT_TIME conditional for ppoll, pselect,
  io_getpevents as per review comments
Changes since v1:
* fixed bug pointed out by arnd

Deepa Dinamani (5):
  signal: Add set_user_sigmask()
  signal: Add restore_user_sigmask()
  ppoll: use __kernel_timespec
  pselect6: use __kernel_timespec
  io_pgetevents: use __kernel_timespec
