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.
Sounds like a worthy goal.
Thanks! This is Arnd's idea to come up with a common script for all the architecture. This implementation is a groundwork to solve Y2038 issue.
I tried applying the patches and it seems they haven't been rebased since v4.18. My rebases are in https://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha.git/log/?h=fo...
I was rebased with 4.19-rc8 before sending v2 (what I remember).
They seem to work for me, FWIW.
Is your plan to have the patches go through the separate architecture trees, or go in together? I think I'd at least prefer for another architecture to take the plunge before alpha.
I would like Arnd's to comment on this as it is my first patch series. As I mentioned in the cover letter this implementation done for 8 architecture- alpha, ia64, m68k, microblaze, parisc, sh, sparc, and xtensa. Most of the review are also done. mips and powerpc are *almost* completed. FYI, The system call table generation script for IA64 merged in linux-next.
