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 ia64, 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 v1: - optimized/updated the syscall table generation scripts. - fixed all mixed indentation issues in syscall.tbl. - added "comments" in syscall.tbl.
