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, microblaze, sparc, 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. Git repo:- https://github.com/frzkhn/system_call_table_generator/ Added an extra patch to add __NR_old_getpagesize macro. Added an extra patch to keep __IGNORE* entries in asm/unistd.h. 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.
