This is the update of the series based on 4.17 kernel
https://github.com/norov/linux/tree/ilp32-4.17
with the following non-critical changes:
 - documentation patch extended with few words about ILP32 in general, and
   the link to ARM document about it added;
 - nds32 and riscv32 exceptions added for ARCH_32BIT_OFF_T and
   {get,set}rlimit (patches 4 and 5).
 - changes to architectures that are unsupported anymore are dropped.
 - Chris Metcalf's ack for patch #3 removed, as it is related to
   tile32 which is unsupported now.

Reminder to Arnd. There's arch subseries acked by you but still
without progress. Could you consider taking it upstream?
[PATCH 03/24] compat ABI: use non-compat openat and open_by_handle_at variants
[PATCH 04/24] 32-bit userspace ABI: introduce ARCH_32BIT_OFF_T config option
[PATCH 05/24] asm-generic: Drop getrlimit and setrlimit syscalls from default list
