From 3807f345b2c610336c17c7624a0d496a38df75a0 Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Mon, 28 Jul 2008 11:47:52 -0300 Subject: x86: paravirt: factor out cpu_khz to common code KVM intends to use paravirt code to calibrate khz. Xen current code will do just fine. So as a first step, factor out code to pvclock.c.
