WARN if KVM_RUN is reached with a vCPU's mp_state set to SIPI_RECEIVED, as
KVM no longer uses SIPI_RECEIVED internally, and should morph SIPI_RECEIVED
into INIT_RECEIVED with a pending SIPI if userspace forces SIPI_RECEIVED.
See commit 66450a21f9 ("KVM: x86: Rework INIT and SIPI handling") for
more history and details.

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 reStructuredText 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.
