    This is the 5.1-based version.
    Changes comparing to 5.0:
    - drop arch patches that has been taken upstream:
    80d7da1cac62 asm-generic: Drop getrlimit and setrlimit syscalls from default list
    942fa985e9f1 32-bit userspace ABI: introduce ARCH_32BIT_OFF_T config option
    0d0216c03a7a compat ABI: use non-compat openat and open_by_handle_at variants
    - in include/linux/thread_bits.h define current_thread_info() prior to
    inclusion of asm/thread_info.h, to avoid circullar dependencies (thread: move
    thread bits accessors to separated file);
    - enable old IPC interfaces for ilp32, according to mainline changes
    (arm64: ilp32: introduce syscall table for ILP32).

    Thanks,
    Yury
