Delete rmap_printk() so that MMU_WARN_ON() and MMU_DEBUG can be morphed into something that can be regularly enabled for debug kernels. The information provided by rmap_printk() isn't all that useful now that the rmap and unsync code is mature, as the prints are simultaneously too verbose (_lots_ of message) and yet not verbose enough to be helpful for debug (most instances print just the SPTE pointer/value, which is rarely sufficient to root cause anything but trivial bugs). Alternatively, rmap_printk() could be reworked to into tracepoints, but it's not clear there is a real need as rmap bugs rarely escape initial development, and when bugs do escape to production, they are often edge cases and/or reside in code that isn't directly related to the rmaps. In other words, the problems with rmap_printk() being unhelpful also apply to tracepoints. And deleting rmap_printk() doesn't preclude adding tracepoints in the future.

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.
