[Qemu-devel] [PULL 6/7] target-i386: Move APIC ID compatibility code to


From: Eduardo Habkost
Subject: [Qemu-devel] [PULL 6/7] target-i386: Move APIC ID compatibility code to pc.c
Date: Mon, 9 Mar 2015 17:40:50 -0300

The APIC ID compatibility code is required only for PC, and now that
x86_cpu_initfn() doesn't use x86_cpu_apic_id_from_index() anymore, that
code can be moved to pc.c.
