Make vcpu_ioctl() a macro wrapper and pretty the _name_ of the ioctl on failure instead of the number. Add inner macros to allow handling cases where the name of the ioctl needs to be resolved higher up the stack, and to allow using the formatting for non-ioctl syscalls without being technically wrong. Deliberately do not use __stringify(), as that will expand the ioctl all the way down to its numerical sequence, again the intent is to print the name of the macro.

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.
