Disallow all flags for KVM-internal memslots as all existing flags require some amount of userspace interaction to have any meaning. In addition to guarding against KVM goofs, explicitly disallowing dirty logging of KVM- internal memslots will (hopefully) allow exempting KVM-internal memslots from the KVM_MEM_MAX_NR_PAGES limit, which appears to exist purely because the dirty bitmap operations use a 32-bit index.

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.
