Test KVM dirty logging functionality.
The test creates a standalone memory slot to test tracking the dirty
pages since we can't really write to the default memory slot which still
contains the guest ELF image.
We have two threads running during the test:
(1) the vcpu thread continuously dirties random guest pages by writting
a iteration number to the first 8 bytes of the page
(2) the host thread continuously fetches dirty logs for the testing
memory region and verify each single bit of the dirty bitmap by
checking against the values written onto the page
Note that since the guest cannot calls the general userspace APIs like
random(), it depends on the host to provide random numbers for the
page indexes to dirty.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
