Once upon a time it used to have a C part that printed a warning about unimplemented OSF syscalls. That's what it's been doing all over the OSF syscall range, while the native Linux syscall range uses sys_ni_syscall(). With those warnings about unimplemented OSF syscalls gone (circa 2.4), alpha_ni_syscall() has shrunk to that little bit of asm and the only reason it hasn't been replaced with sys_ni_syscall() everywhere is that extra twist needed in case of syscall #0. Let's keep it only for syscall #0 and replace the rest with sys_ni_syscall. And use sys_ni_syscall for "number out range" in ptraced-call case, as we'd been doing for normal codepath since 2.1.86...

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
