x86/xen: make CONFIG_XEN depend on CONFIG_X86_LOCAL_APIC
Since commit feb44f1f7a4ac299d1ab1c3606860e70b9b89d69 (x86/xen: Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need a full APIC driver and thus should depend on X86_LOCAL_APIC. This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by disabling Xen support in this configuration. Users needing Xen support in a non-SMP i386 kernel will need to enable CONFIG_X86_UP_APIC. Signed-off-by: David Vrabel <david.vrabel@citrix.com> Cc: <stable@vger.kernel.org>
