From e1356dd70aef11425883dd4d2885f1d208eb9d57 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Thu, 18 Dec 2014 23:31:11 -0200 Subject: [PATCH] target-i386: Require APIC ID to be explicitly set before CPU realize Instead of setting APIC ID automatically when creating a X86CPU, require the property to be set before realizing the object (which all callers of cpu_x86_create() already do).
