[PATCH v6 0/5] parisc: system call table generation support

by Firoz Khan

The purpose of this patch series is, we can easily add/modify/delete system call table support by changing 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 respective 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 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, ia64, m68k, micro- blaze, mips, powerpc, sh, sparc, and xtensa. Below mentioned git repository contains more details. Git repo:- 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.

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. Firoz Khan (5): parisc: move __IGNORE* entries to non uapi header parisc: add __NR_Linux_syscalls macro with __NR_syscalls parisc: add system call table generation support parisc: uapi header and system call table file generation parisc: add __IGNORE* entries in asm/unistd.h arch/parisc/Makefile | 4 + arch/parisc/include/asm/Kbuild | 3 + arch/parisc/include/asm/unistd.h | 9 + arch/parisc/include/uapi/asm/Kbuild | 2 + arch/parisc/include/uapi/asm/unistd.h | 380 +----------------------- arch/parisc/kernel/syscall.S | 12 +- arch/parisc/kernel/syscall_table.S | 459 ----------------------------- arch/parisc/kernel/syscall_table_32.S | 13 + arch/parisc/kernel/syscall_table_64.S | 20 ++ arch/parisc/kernel/syscalls/Makefile | 55 ++++ arch/parisc/kernel/syscalls/syscall_32.tbl | 342 +++++++++++++++++++++ arch/parisc/kernel/syscalls/syscall_64.tbl | 342 +++++++++++++++++++++ arch/parisc/kernel/syscalls/syscallhdr.sh | 35 +++ arch/parisc/kernel/syscalls/syscalltbl.sh | 42 +++ 14 files changed, 877 insertions(+), 841 deletions(-) delete mode 100644 arch/parisc/kernel/syscall_table.S create mode 100644 arch/parisc/kernel/syscall_table_32.S create mode 100644 arch/parisc/kernel/syscall_table_64.S create mode 100644 arch/parisc/kernel/syscalls/Makefile create mode 100644 arch/parisc/kernel/syscalls/syscall_32.tbl create mode 100644 arch/parisc/kernel/syscalls/syscall_64.tbl create mode 100644 arch/parisc/kernel/syscalls/syscallhdr.sh create mode 100644 arch/parisc/kernel/syscalls/syscalltbl.sh -- 1.9.1
