Sean Christopherson af2d85d34d KVM: selftests: Precisely track number of dirty/clear pages for each iteration
Track and print the number of dirty and clear pages for each iteration.
This provides parity between all log modes, and will allow collecting the
dirty ring multiple times per iteration without spamming the console.

Opportunistically drop the "Dirtied N pages" print, which is redundant
and wrong.  For the dirty ring testcase, the vCPU isn't guaranteed to
complete a loop.  And when the vCPU does complete a loot, there are no
guarantees that it has *dirtied* that many pages; because the writes are
to random address, the vCPU may have written the same page over and over,
i.e. only dirtied one page.

While the number of writes performed by the vCPU is also interesting,
e.g. the pr_info() could be tweaked to use different verbiage, pages_count
doesn't correctly track the number of writes either (because loops aren't
guaranteed to a complete).  Delete the print for now, as a future patch
will precisely track the number of writes, at which point the verification
phase can report the number of writes performed by each iteration.

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.
