Xen PV domain kernel is not by design affected by meltdown as it's enforcing split CR3 itself. Let's not report such systems as "Vulnerable" in sysfs (we're also already forcing PTI to off in X86_HYPER_XEN_PV cases); the security of the system ultimately depends on presence of mitigation in the Hypervisor, which can't be easily detected from DomU; let's report that.

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.
