Merge tag 'y2038-syscall-abi' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground into timers/2038

Pull additional syscall ABI cleanup for y2038 from Arnd Bergmann:

This is a follow-up to the y2038 syscall patches already merged in the tip
tree.  As the final 32-bit RISC-V syscall ABI is still being decided on,
this is the last chance to make a few corrections to leave out interfaces
based on 32-bit time_t along with the old off_t and rlimit types.

The series achieves this in a few steps:

- A couple of bug fixes for minor regressions I introduced
  in the original series

- A couple of older patches from Yury Norov that I had never
  merged in the past, these fix up the openat/open_by_handle_at and
  getrlimit/setrlimit syscalls to disallow the old versions of off_t
  and rlimit.

- Hiding the deprecated system calls behind an #ifdef in
  include/uapi/asm-generic/unistd.h

- Change arch/riscv to drop all these ABIs.

Originally, the plan was to also leave these out on C-Sky, but that now
has a glibc port that uses the older interfaces, so we need to leave
them in place.
