Hi all,

This series enables AARCH64 with ILP32 mode.

As supporting work, it introduces ARCH_32BIT_OFF_T configuration
option that is enabled for existing 32-bit architectures but disabled
for new arches (so 64-bit off_t userspace type is used by new userspace).
Also it deprecates getrlimit and setrlimit syscalls prior to prlimit64.

Based on kernel v4.16. Tested with LTP, glibc testsuite, trinity, lmbench,
CPUSpec.

v9: - rebased on top of v4.16;
    - signal subsystem reworked to avoid code duplication, as requested
      by Dave Martin (patches 18 and 20);
    - new files introduced in series use SPDX notation for license;
    - linux-api and linux-arch CCed as the series changes kernel ABI;
    - checkpatch and other minor fixes.
    - Zhou Chengming's reported-by for patch 2 and signed-off-by for
      patch 21 removed because his email became invalid. Zhou, please
      share your new email.

This is 4.20-based version.

There's no important changes comparing to 4.19, but I would like to remind
that this series contains some generic arch patches that ACKed, but still
not upstreamed:
Yury Norov      asm-generic: Drop getrlimit and setrlimit syscalls from default list
Yury Norov      32-bit userspace ABI: introduce ARCH_32BIT_OFF_T config option
Yury Norov      compat ABI: use non-compat openat and open_by_handle_at variants
James Morse     ptrace: Add compat PTRACE_{G,S}ETSIGMASK handlers
Dave Martin     arm64: signal: Make parse_user_sigframe() independent of rt_sigframe layout

Please also notice that my email address is changed, from now it's
