Instead of switching XPTI globally on or off add a per-domain flag for that purpose. This allows to modify the xpti boot parameter to support running dom0 without Meltdown mitigations. Using "xpti=no-dom0" as boot parameter will achieve that. Move the xpti boot parameter handling to xen/arch/x86/pv/domain.c as it is pv-domain specific.

xen-bugtool =========== The xen-bugtool command line application will collate the Xen dmesg output, details of the hardware configuration of your machine, information about the build of Xen that you are using, plus, if you allow it, various logs. The information collated can either be posted to a Xen Bugzilla bug (this bug must already exist in the system, and you must be a registered user there), or it can be saved as a .tar.bz2 for sending or archiving. The collated logs may contain private information, and if you are at all worried about that, you should not use this tool, or you should explicitly exclude those logs from the archive. xen-bugtool is wholly interactive, so simply run it, and answer the questions.
