Drop _kvm_ioctl(), _vm_ioctl(), and _vcpu_ioctl(), as they are no longer used by anything other than the no-underscores variants (and may have never been used directly). The single-underscore variants were never intended to be a "feature", they were a stopgap of sorts to ease the conversion to pretty printing ioctl() names when reporting errors. Opportunistically add a comment explaining when to use __KVM_IOCTL_ERROR() versus KVM_IOCTL_ERROR(). The single-underscore macros were subtly ensuring that the name of the ioctl() was printed on error, i.e. it's all too easy to overlook the fact that using __KVM_IOCTL_ERROR() is intentional.

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.
