WARN if KVM attempts to set vCPU affinity when posted interrupts aren't enabled, as KVM shouldn't try to enable posting when they're unsupported, and the IOMMU driver darn well should only advertise posting support when AMD_IOMMU_GUEST_IR_VAPIC() is true. Note, KVM consumes is_guest_mode only on success.

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.
