This will be an automated scripts to provide easy support for add/modify/delete the system call entry by add in respective *.tbl file.
System call table generation support for asm-generic is provide for arm64 architecture which will use the common scripts resides in scripts directory and use syscall.tbl syscall_arm32.tbl files as inputs. This implementation will replace asm-generic/unistd.h.

Firoz Khan (3): arm64: add system call table generation files arm64: assign __NR_*_Linux_syscalls generated by the scripts arm64: generate uapi and kapi headers

Add Makefile changes to invoke the system call table generation script which is placed in scripts directory as a common location accessible for all the architectures.
Add syscall_arm32.tbl in syscalls directory which is copied from arch/arm/tools/syscall.tbl and made some changes as per the req- uirement which will be used as input for the scripts which gene- rate the uapi and kapi headers.

Assign the generated values - __NR_C32_Linux_syscalls and __NR_64_Linux_syscalls instead of __NR_compat_syscalls and __NR_syscalls respectively. It is better than hard coding it.
One of the patch in the patch series will generate the headers and calculate the total number of syscalls that can be assigned. Otherwise the hard coded values need to be changed whenever we either add a new system call or delete a existing system call.

Unified system call table generation script need to be invoked to generated the uapi and kapi headers. The Makefile changes present in this patch will invoke the scripts and generate uapi and kapi header files.
The generated files - unistd_*.h and syscall_table_*.h files will be included by unistd.h, sys.c and sys32.c files by rep- lacing asm-generic/unistd.h file.

Hi Firoz,
Thank you for the patch! Yet something to improve:

I'm having a hard time understanding what the benefit of this series is, given that we only support EABI compat tasks. When adding a new compat system call, you can't just blindly hook it up without checking whether it needs a wrapper to deal with any type conversion etc, so really we're just replacing one table with another as far as I can tell. What am I missing?
I also really don't think we should be generating the 32-bit UAPI headers from the 64-bit compat system call support (if that's what you're trying to do -- make headers_check fails with your patches applied). arch/arm/ is the canonical place for the 32-bit UAPI, and we're just implementing that.

The point that is missing in the description above is that all unistd.h and syscall.S files are now being generated from a .tbl file, across all architectures. This was already done on arm32, x86 and s390 before 4.20, but is now done on all architectures that don't use the uapi/asm-generic/unistd.h header, and the arm32 compat version for arm64.
The newly added file has the same format as all other tables, and will be easier to synchronize with the arm32 version, which has almost the same contents (arm32 has oabi support, arm64 has compat support).
I also really don't think we should be generating the 32-bit UAPI headers from the 64-bit compat system call support (if that's what you're trying to do -- make headers_check fails with your patches applied). arch/arm/ is the canonical place for the 32-bit UAPI, and we're just implementing that.
I think you just misread what Firoz was trying to say here: The arm64 uapi/asm/unistd.h file is now being generated from the generic syscall.tbl file, while the compat asm/unistd32.h file is not part of the UAPI. In both cases though, the data from the old files is being replaced with data in the more compact and (hopefully) more readable format.

Hi Arnd, Will,
thanks for the email.
I'm want to abandon this patch series. Will post new patch series for system call table generation support for asm-generic and some other stuff together by end of this week or early next week.
Thanks Firoz
