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.
https://github.com/frzkhn/system_call_table_generator/
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__.

sys_getpagesize entry is present in kernel/entry.S file to support for old user interface. So we need to add an uapi entry too.
Add __NR_old_getpagesize in uapi/asm/unistd.h in order to not break old user space as it is reserved for backwards compatibility with old __NR_getpagesize.

NR_syscalls macro holds the number of system call exist in ia64 architecture. We have to change the value of NR- _syscalls, if we add or delete a system call.
One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_sy- scalls value.
1. Update NR_syscalls in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_sys- calls until we either add a new system call or delete existing system call.
2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_syscalls in asm/unistd.h file.
The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_syscalls asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

The system call number in ia64 architecture starts with 1024. But most of the other architecute starts with 0. In order to come up with a common implementation to generate uapi header we need to add an offset - __NR_Linux with a value 1024.
One of the patch in this patch series does have a script to generate uapi header which uses syscall.tbl file. In syscall- .tbl contain system call number. With the use of __NR_Linux, we can start the number from 0 instead of 1024.

The system call tables are in different format in all architecture and it will be difficult to manually add, modify or delete the syscall table entries in the res- pective files. To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures.
The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts.
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.
syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_64.h and syscall_table.h files respectively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_64.h will be included by uapi/asm/unistd.h and syscall_table.h is included by kernel/entry.S - the real system call table.
ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

System call table generation script must be run to gener- ate unistd_64.h and syscall_table.h files. This patch will have changes which will invokes the script.
This patch will generate unistd_64.h and syscall_table.h files by the syscall table generation script invoked by ia64/Makefile and the generated files against the removed files must be identical.
The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/entry.S file.

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.
Replaced v4 with this new version in my "next" branch.
Thanks
