To allow testing of vfork() support in the arm64 basic-gcs test provide an implementation for nolibc, using the vfork() syscall if one is available and otherwise clone3(). We implement in terms of clone3() since the order of the arguments for clone() varies between architectures. As for fork() SPARC returns the parent PID rather than 0 in the child for vfork() so needs custom handling.

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 reStructuredText 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.
