The purpose of this patch series is:
1. We can easily add/modify/delete system call by changing entry
in syscall.tbl file. No need to manually edit many files.
2. It is easy to unify the system call implementation across all
the architectures.
The system call tables are in different format in all architecture
and it will be difficult to manually add or modify the system calls
in the respective files manually. To make it easy by keeping a script
and which'll generate the header file and syscall table file so this
change will unify them across all architectures.
syscall.tbl contains the list of available system calls along with
system call number and corresponding entry point. Add a new system
call in this architecture will be possible by adding new entry in
the syscall.tbl file.
Adding a new table entry consisting of:
- System call number.
- ABI.
- System call name.
- Entry point name.
- Compat entry name, if required.
ARM, s390 and x86 architecuture does exist the similar support. I
leverage their implementation to come up with a generic solution.
I have done the same support for work for alpha, ia64, sparc, mips,
parisc, powerpc, sh, sparc, and xtensa. But I started sending
the patch for one architecuture for review. Below mentioned git
repository contains more details.

Finally, this is the ground work for solving the Y2038 issue. We
need to add/change two dozen of system calls to solve Y2038 issue.
So this patch series will help to easily modify from existing
system call to Y2038 compatible system calls.

I started working system call table generation on 4.17-rc1. I used
marcin's script - https://github.com/hrw/syscalls-table to generate
the syscall.tbl file. And this will be the input to the system call
table generation script. But there are couple system call got add
in the latest rc release. If run Marcin's script on latest release,
it will generate a different syscall.tbl. But I still use the old
file - syscall.tbl and once all review got over I'll update
syscall.tbl alone w.r.to the tip of the kernel. The impact of this
is, few of the system call won't work.
