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.

All the __IGNORE* entries are resides in the uapi header file move to non uapi header asm/unistd.h as it is not used by any user space applications.
It is correct to keep __IGNORE* entry in non uapi header asm/unistd.h while uapi/asm/unistd.h must hold information only useful for user space applications.
One of the patch in this patch series will generate uapi header file. The information which directly used by the user space application must be present in uapi file.

__NR_Linux_syscalls macro holds the number of system call exist in parisc architecture. We have to change the value of __NR_Linux_syscalls, if we add or delete a system call.
One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update __NR- _Linux_syscalls value.
1. Update __NR_Linux_syscalls in asm/unistd.h manually by counting the no.of system calls. No need to update __NR- _Linux_syscalls until we either add a new system call or delete existing system call.
2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update __NR_Linux_syscalls in asm/unistd.h file.
The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with __NR_Linux_syscalls asm/unistd.h. The macro __NR_sys- calls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

The system call tables are in different format in all architecture and it will be difficult to manually add, modify or delete the syscall table entries in the res- pective files. To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures.
The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be 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. - Compat entry name, if required.
syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_32/64.h and syscall_table_32/64/c32.h files respect- ively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_32/64.h will be included by uapi/asm/unistd.h and syscall_table_32/64/- c32.h is included by kernel/syscall.S - the real system call table.
ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

System call table generation script must be run to gener- ate unistd_32/64.h and syscall_table_32/64/c32.h files. This patch will have changes which will invokes the script.
This patch will generate unistd_32/64.h and syscall_table- _32/64/c32.h files by the syscall table generation script invoked by parisc/Makefile and the generated files against the removed files must be identical.
The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/syscall.S file.

This adds an exception to the syscall table checking script.
nfsservctl entry is only provided on x86, and there is no reason to add it elsewhere. However, including it on the syscall table caused a warning for most configurations on non-x86.
