y2038: additional syscall ABI cleanup

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.

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.

All new 32-bit architectures should have 64-bit off_t type on
userspace side which corresponds to the loff_t kernel type. This
is the requirement for modern ABIs. Some existing architectures
still support 32-bit off_t. This option is enabled for all such
architectures explicitly.
