    tools/x86emul: Use struct cpuid_policy in the userspace test harnesses
    This will shortly be required to pass into the emulator itself.
    Simplify the shared cpu_has_* helpers by reading the correct bit out of the
    CPUID policy itself.
    No (intended) change in behaviour.

    libx86: Split x86_cpuid_policy_fill_native() out of calculate_raw_policy()
    This will shortly be wanted by the userspace emulator harnesses as well.
    Consolidate the cpuid{,_count}_leaf() helpers beside the structure 
    rather than having them scattered throughout Xen.

    guest/pvh: special case the low 1MB
    When running as a PVH guest Xen only special cases the trampoline
    code in the low 1MB, without also reserving the space used by the
    relocated metadata or the trampoline stack.
    Fix this by always reserving the low 1MB regardless of whether Xen is
    running as a guest or natively.

    guest/pvh: fix handling of multiboot module list
    When booting Xen as a PVH guest the data in the PVH start info
    structure is copied over to a multiboot structure and a module list
    array that resides in the .init section of the Xen image. The
    resulting multiboot module list is then handed to the generic boot
    process using the physical address in mbi->mods_addr.
    This works fine as long as the Xen image doesn't relocate itself, if
    there's such a relocation the physical addresses of multiboot module
    list is no longer valid.
    Fix this by handing the virtual address of the module list to the
    generic boot process instead of it's physical address.
