[PATCH 0/5] Xen: Add support for xl.cfg passthrough setting

Hi All, Note: This series is based on Marek's patches adding support for e820_host https://www.redhat.com/archives/libvir-list/2020-April/msg00633.html which I've ACK'ed, but am waiting to commit until this related setting is hashed out. This series adds support for Xen's xl.cfg(5) 'passthrough' setting. Starting with xen 4.13 this setting must be enabled in order to assign PCI passthrough devices to a guest. libxl will enable it automatically if the guest config has PCI devices at creation time, but otherwise 'passthrough' must be enabled to hotplug PCI devices. The passthrough setting is mapped to a xen hypervisor feature of the same name. Xen hypervisor features were recently added by the series mentioned above.
