From 87ffd2b9bb74061c120f450e4d0f3409bb603ae0 Mon Sep 17 00:00:00 2001 From: David Vrabel Date: Thu, 20 Aug 2015 11:33:41 +0100 Subject: 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.
