Despite LPIs not having an active state, *virtual* LPIs do have one, which gets cleared on EOI. So far, so good. However, this leads to a small problem: when an active LPI is not in the LRs, that EOImode==0 and that the guest EOIs it, EOIcount doesn't get bumped up. Which means that in these condition, the LPI would stay active forever. Clearly, we can't have that. So if we spot an active LPI, we drop that state. It's pretty pointless anyway, and only serves as a way to trip SW over.

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.
