Some Intel processors have an EPT feature whereby the accessed & dirty bits in EPT entries can be updated by HW. MSR IA32_VMX_EPT_VPID_CAP exposes the presence of this capability. There is no point in trying to use that new feature bit in the VMX code as VMX needs to read the MSR anyway to access other bits, but having the feature bit for EPT_AD in place helps virtualization management as it exposes "ept_ad" in /proc/cpuinfo/$proc/flags if the feature is present.

README
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.
