Subject: [PATCH 0/8] y2038: remove time32 ABI on rv32 and csky

This is a follow-up to the y2038 syscall patches that Thomas already
merged. Both the csky and riscv maintainers have requested that the
time_t syscall ABI should be completely converted before an official
glibc port is merged.

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

- Changing the two architectures to use the new style
  syscall ABI for all three types: loff_t, rusage, and
  time_t.

Arnd Bergmann (5):
  asm-generic: Make time32 syscall numbers optional
  unicore32: Fix __ARCH_WANT_STAT64 definition
  checksyscalls: fix up mq_timedreceive and stat exceptions
  csky: Use latest system call ABI
  riscv: Use latest system call ABI

Yury Norov (3):
  compat ABI: use non-compat openat and open_by_handle_at variants
  32-bit userspace ABI: introduce ARCH_32BIT_OFF_T config option
  asm-generic: Drop getrlimit and setrlimit syscalls from default list
