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. 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.

The system call table generation script is added in
syscalls directory which contain the script to generate
both uapi header file system call table generation file
and syscall_32/64.tbl file which'll be the input for the
scripts.

syscall_32/64.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_32/64.tbl file.

Adding a new table entry consisting of:
        - System call number.
        - ABI.
        - System call name.
        - Entry point name.
	- Compat entry name, if required.

syscallhdr.sh and syscalltbl.sh will generate uapi header-
unistd_32/64.h and syscall_table_32/64/c32.h files respectively.
File syscall_table_32/64/c32.h is included by syscall.S - the
real system call table. Both .sh files will parse the content
syscall.tbl to generate the header and table files.

ARM, s390 and x86 architecuture does have the similar support.
I leverage their implementation to come up with a generic
solution.

I would argue that for sparc we only want a single input
table, since the 32/64 versions are similar enough that the
differences can be addressed with 'abi' flag, rather than
having everything marked as 'common'. Isn't that the
purpose of the abi flag in the first place?

Yes, we can do that way also. But few concerns I would
like to share with you.

I feel it add the complexity in the scripts. eg:-

108     32    setresuid32                     sys_setresuid
108     64    setresuid                         sys_setresuid
This case the script has to be smart enough to parse the
.tbl file properly. It need more logic in the scripts. This is
not common. So if you keep separate .tbl we can avoid
this.

ABI flag is serving *nothing* in all other architecture including
SPARC.

But as I told in the cover letter, I followed x86/arm/
s390 architecture's system table generation implementation.
They are keeping ABI flag. In our case we can delete this
flag completely from all architectures.

Most of the architecture these 32/64 similarity is absent.
So it would be better keep separate files to maintain a
generic script across all architecture.

One question here is; while invoking the script I'm passing
the abi flag. It is simply keeping in the .tbl file to make the
file similar to x86.  What I can do here?
