From 950f147249643635289003d7dd291915ad330b29 Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Tue, 9 Jun 2009 12:15:18 -0400 Subject: [PATCH] provide cpu_index to env mapping There are some people interested in, given a cpu number, pick its CPUState. KVM is an example, although not yet in tree. This patch provides a way of doing that.
