It is more accurate to check if KVM is enabled, instead of having the architecture say so. Architectures always "have" KVM, so for example checking CONFIG_HAVE_KVM in x86 code is pointless, but if KVM is disabled in a specific build, there is no need for support code. Alternatively, many of the #ifdefs could simply be deleted. However, this would add completely dead code. For example, when KVM is disabled, there should not be any posted interrupts, i.e. NOT wiring up the "dummy" handlers and treating IRQs on those vectors as spurious is the right thing to do.

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.
