diag14() is currently only used by the vmur device driver. The third parameter, called subcommand, determines the type of the first parameter. For some subcommands the value of the first parameter is an address to a memory buffer and needs virtual to physical address conversion. Other subcommands interpret the first parameter is an integer. This doesn't fix a bug since virtual and physical addresses are currently the same.

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.
