[PATCH v2 4/5] m68k: uapi header and system call table file generation
System call table generation script must be run to generate unistd_32.h and syscall_table.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32.h and syscall_table.h files by the syscall table generation script invoked by arch/m68k/Makefile and the generated files against the removed files will be identical. The generated uapi header file will be included in uapi/asm/unistd.h and generated system call table support file will be included by arch/m68k/kernel/syscall_table.S file.

[PATCH v2 3/5] m68k: Added system call table generation support
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. 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. The system call table generation script is added in syscalls directory which contain the script to generate both uapi header file system call table generation file and syscall.tbl file which'll be the 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.h and syscall_table.h files respectively. File syscall_table.h is included by syscall_table.S - the real system call table. Both .sh files will parse the content syscall.tbl to generate the header and table files. ARM, s390 and x86 architecuture does have the similar support. I leverage their implementation to come up with a generic solution. And this is the ground work for y2038 issue. We need to change two dozons of system call implementation and this work will reduce the effort by simply modify two dozon entries in syscall.tbl.

[PATCH v2 1/5] m68k: Rename system call table file name
The system call table entries are present in syscalltable.S. One of the patch in this patch series will auto-generate the system call table entries using the system call table generation script and which'll replace the existig table file. In order to come up with a common naming convention across all architecture, we need to change the file name to syscall_table.S. This change will unify the implementation across all architecture.

I posted similar script for 10 different architectures. I got few good review from the maintainers and it will be applicable for all the architectures including m68k. There are few area which I identified need to improve. This will take couple of days. But it will be very helpful if you can perform the boot test on the actual platform and share the result. FYI, Keeping a single script is always our plan for long run. But I have to keep a separate versions for the start so each architecture can be handled in one series. Which would make easier to merge in the initial version. we could probably add it to scripts/*.sh first, but that requires more coordination between the architectures. - Firoz > > Gr{oetje,eeting}s, > > Geert > > -- > Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- > ge...@linux-m68k.org > > In personal conversations with technical people, I call myself a hacker.
