    Subject[PATCH v2 0/5] System call table generation support
    Date
    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,
    m68k, mips, 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 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.

    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
