Comment 9 for bug 1858461

Hello, thank you. I want to introduce another patch with syscalls related generator. Please review it.

I think about the following development flow:

1. Kernel updates and maintains "tbl".
2. Qemu developer wants to implement new syscall (like clone3) in "linux-user/syscall.c".
3. Developer clones new kernel into some directory and runs generators.
4. All syscall related stuff will be updated immediately.

I think it will very straightforward solution. Qemu won't hardcode kernel related stuff and all linkage between kernel and qemu will be very easy.
