The next patch would use kvm_emulate_instruction() with EMULTYPE_SKIP in complete_userspace_io callback to fix a problem in msr access emulation. However, EMULTYPE_SKIP only updates RIP, more things like updating interruptibility state and injecting single-step #DBs would be done in the callback. Since the emulator also does those things after x86_emulate_insn(), add a new emulation type to pair with EMULTYPE_SKIP to do those things for completion of user exits within the emulator.

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.
