Pull xen fixes from Juergen Gross:
 "Two minor fixes for running as Xen dom0:

   - when built as 32 bit kernel on large machines the Xen LAPIC
     emulation should report a rather modern LAPIC in order to support
     enough APIC-Ids

   - The Xen LAPIC emulation is needed for dom0 only, so build it only
     for kernels supporting to run as Xen dom0"
