KVM MMIO Stale Data mitigation cleanup for 6.17 Rework KVM's mitigation for the MMIO State Data vulnerability to track whether or not a vCPU has access to (host) MMIO based on the MMU that will be used when running in the guest. The current approach doesn't actually detect whether or not a guest has access to MMIO, and is prone to false negatives (and to a lesser extent, false positives), as KVM_DEV_VFIO_FILE_ADD is optional, and obviously only covers VFIO devices.
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.
