On some (probably misconfigured) systems, the torture-test scripting will cause qemu to complain about missing EFI firmware, often because qemu is trying to traverse broken symbolic links to find that firmware. Which is a bit silly given that the default torture-test guest OS has but a single binary for its userspace, and thus is unlikely to do much in the way of networking in any case. This commit therefore avoids such problems by specifying "-net none" to qemu unless the TORTURE_QEMU_INTERACTIVE environment variable is set (for example, by having specified "--interactive" to kvm.sh), in which case "-net nic -net user" is specified to qemu instead. Either choice may be overridden by specifying the "-net" argument of your choice to the kvm.sh "--qemu-args" parameter.

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.
