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, m68k, microblaze,
ia64, mips, parisc, sh, sparc, and xtensa. But I started sending
the patch for one architecuture for review. Below mentioned git
repository contains more details.
Git repo:- https://github.com/frzkhn/system_call_table_generator/
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 new 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 thing, few
of the system call won't work.

Sure. Basically I haven't came across changelog till a point

The purpose of this patch series is, we can easily
add/modify/delete system call table support by cha-
nging entry in syscall.tbl file instead of manually
changing many files. The other goal is to unify the
system call table generation support implementation
across all the architectures.
The system call tables are in different format in
all architecture. It will be difficult to manually
add, modify or delete the system calls in the resp-
ective files manually. To make it easy by keeping a
script and which'll generate uapi header file and
syscall table file.
syscall.tbl contains the list of available system
calls along with system call number and correspond-
ing entry point. Add a new system call in this arch-
itecture 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.
ARM, s390 and x86 architecuture does exist the sim-
ilar support. I leverage their implementation to come
up with a generic solution.
I have done the same support for work for alpha, ia64,
m68k, microblaze, mips, parisc, powerpc, sh and sparc.
Below mentioned git repository contains more details

- changed from generic-y to generated-y in Kbuild.
- removed the patch "0001-xtensa-move-SYS_XTENSA_-
macros-to-non-uapi-header.patch".

xtensa: add __NR_syscalls along with __NR_syscall_count
xtensa: add system call table generation support
xtensa: generate uapi header and syscall table header files

The purpose of this patch series is, we can easily
add/modify/delete system call table support by cha-
nging entry in syscall.tbl file instead of manually
changing many files. The other goal is to unify the
system call table generation support implementation
across all the architectures.
The system call tables are in different format in
all architecture. It will be difficult to manually
add, modify or delete the system calls in the resp-
ective files manually. To make it easy by keeping a
script and which'll generate uapi header file and
syscall table file.
syscall.tbl contains the list of available system
calls along with system call number and correspond-
ing entry point. Add a new system call in this arch-
itecture 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.
ARM, s390 and x86 architecuture does exist the sim-
ilar support. I leverage their implementation to
come up with a generic solution.
I have done the same support for work for alpha, m68k,
microblaze, mips, parisc, powerpc, sh, sparc and xtensa.
Below mentioned git repository contains more details
about the workflow.

Finally, this is the ground work to solve the Y2038
issue. We need to add two dozen of system calls to
solve Y2038 issue. So this patch series will help to
add new system calls easily by adding new entry in
the syscall.tbl.
changes since v4:
- changed from generic-y to generated-y in Kbuild.
changes since v3:
- optimized/updated the syscall table generation
scripts.
- fixed all mixed indentation issues in syscall.tbl.
- added "comments" in syscall.tbl.
- removed __IGNORE entries which was added in v2
to suppress the warning.
changes since v2:
- fixed the offset logic in the script.
- added missing new line.
changes since v1:
- enclosed __NR_sycalls macro with __KERNEL__.

ia64: add __NR_syscalls along with NR_syscalls
ia64: add an offset for system call number
