This is a follow-up cleanup after switching to the generic syscalltbl.sh. The old x86 specific script skipped non-existing syscalls. So, the generated syscalls_64.h, for example, had a big hole in the syscall numbers 335-423 range. That is why there exists [0 ... __NR_*_syscall_max] = &__*_sys_ni_cyscall. The new script, scripts/syscalltbl.sh automatically fills holes with __SYSCALL(<nr>, sys_ni_syscall), hence such ugly code can go away. The designated initializers, '[nr] =' are also unneeded. Also, there is no need to give __NR_*_syscall_max+1 because the array size is implied by the number of syscalls in the generated headers. Hence, there is no need to include <asm/unistd.h>, either.

README
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.
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.
