From 2d826404f0bdcac2a4dd7e3c446b70d6a3b63b78 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 20 Aug 2009 17:06:25 +0200 Subject: x86: Move tsc_calibration to x86_init_ops TSC calibration is modified by the vmware hypervisor and paravirt by separate means. Moorestown wants to add its own calibration routine as well. So make calibrate_tsc a proper x86_init_ops function and override it by paravirt or by the early setup of the vmware hypervisor.
