Jan Beulich cae7d81a37 xen/x86: allow PVH Dom0 without XEN_PV=y ... Decouple XEN_DOM0 from XEN_PV, converting some existing uses of XEN_DOM0 to a new XEN_PV_DOM0. (I'm not convinced all are really / should really be PV-specific, but for starters I've tried to be conservative.) For PVH Dom0 the hypervisor populates MADT with only x2APIC entries, so without x2APIC support enabled in the kernel things aren't going to work very well. (As opposed, DomU-s would only ever see LAPIC entries in MADT as of now.) Note that this then requires PVH Dom0 to be 64-bit, as X86_X2APIC depends on X86_64. In the course of this xen_running_on_version_or_later() needs to be available more broadly. Move it from a PV-specific to a generic file, considering that what it does isn't really PV-specific at all anyway. Note that xen/interface/version.h cannot be included on its own; in enlighten.c, which uses SCHEDOP_* anyway, include xen/interface/sched.h first to resolve the apparently sole missing type (xen_ulong_t).
