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
