The selftests build four kernel modules which use copy-pasted Makefile targets. This is a bit messy, and doesn't scale so well when we add more modules, so let's consolidate these rules into a single rule generated for each module name, and move the module sources into a single directory. To avoid parallel builds of the different modules stepping on each other's toes during the 'modpost' phase of the Kbuild 'make modules', the module files should really be a grouped target. However, make only added explicit support for grouped targets in version 4.3, which is newer than the minimum version supported by the kernel. However, make implicitly treats pattern matching rules with multiple targets as a grouped target, so we can work around this by turning the rule into a pattern matching target. We do this by replacing '.ko' with '%ko' in the targets with subst().

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.
