The purpose of this patch series is, we can easily add/modify/delete
system call table support by changing 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 respective 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 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, microblaze, sparc,
m68k, mips, 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 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.

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.

There are only two 64-bit architecture ports that have a 32-bit
suseconds_t: sparc64 and parisc64. I've encountered a number of problems
with this, while trying to get a proper 64-bit time_t working on 32-bit
architectures. Having a 32-bit suseconds_t combined with a 64-bit time_t
means that we get extra padding in data structures that may leak kernel
stack data to user space, and it breaks all code that assumes that
timespec and timeval have the same layout.
While we can't change sparc64, it seems that glibc on parisc64 has always
set suseconds_t to 'long', and the current version would give incorrect
results for gettimeofday() and many other interfaces: timestamps passed
from user space into the kernel result in tv_usec being always zero
(the lower bits contain the intended value but are ignored) while data
passed from the kernel to user space contains either zeroes or random
data in tv_usec.
Based on that, it seems best to change the user API in the kernel in
an incompatible way to match what glibc expects.
Note that the distros I could find (gentoo and debian) all just
have 32-bit user space, which does not suffer from this problem.

2.18.0
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,
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 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.
