From 9c8c76f921175f7cebcd3cd61d9086c333b96e35 Mon Sep 17 00:00:00 2001 From: gibbs Date: Sat, 5 Oct 2013 23:11:01 +0000 Subject: Formalize the concept of virtual CPU ids by adding a per-cpu vcpu_id field. Perform vcpu enumeration for Xen PV and HVM environments and convert all Xen drivers to use vcpu_id instead of a hard coded assumption of the mapping algorithm (acpi or apic ID) in use.
