Yell loudly if KVM attempts to load CS outside of Real Mode without an accompanying control transfer type, i.e. on X86_TRANSFER_NONE. KVM uses X86_TRANSFER_NONE when emulating IRET and exceptions/interrupts for Real Mode, but IRET emulation for Protected Mode is non-existent. WARN instead of trying to pass in a less-wrong type, e.g. X86_TRANSFER_RET, as emulating IRET goes even beyond emulating FAR RET (which KVM also doesn't fully support).

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.
