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.

parisc: remove __NR_Linux from uapi header file.

The __NR_Linux defined as 0 to support HP-UX syscalls along
with an offset to other system call. But support for HP-UX
is gone and there is no need to define __NR_Linux as 0.

One of the patch in this patch series will generate uapi header
file which does have offset logic support. But here the offset
value __NR_Linux defined as 0 and it doesn't make much effect.
So remove the offset __NR_Linux from uapi header file.

parisc: add __NR_syscalls along with __NR_Linux_syscalls

__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.

parisc: move __IGNORE* entries to non uapi header

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.

License cleanup: add SPDX license identifier to uapi header files with no license

Many user space API headers are missing licensing information, which
makes it hard for compliance tools to determine the correct license.

By default are files without license information under the default
license of the kernel, which is GPLV2. Marking them GPLV2 would exclude
them from being included in non GPLV2 code, which is obviously not
intended. The user space API headers fall under the syscall exception
which is in the kernels COPYING file:

NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".

otherwise syscall usage would not be possible.

Update the files which contain no license information with an SPDX
license identifier. The chosen identifier is 'GPL-2.0 WITH
Linux-syscall-note' which is the officially assigned identifier for the
Linux syscall exception. SPDX license identifiers are a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.

We seem to be nearly the only platform which does not provide the

behave like all other platforms too and don't need extra patches which
are hard to get upstream anyway because we are not a mainstream
