From e93353c93a3ba4215633ce930784f40a4e94e3f9 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Fri, 5 Dec 2008 18:36:45 -0200 Subject: x86: KVM guest: kvm_get_tsc_khz: return khz, not lpj kvm_get_tsc_khz() currently returns the previously-calculated preset_lpj value, but it is in loops-per-jiffy, not kHz. The current code works correctly only when HZ=1000.
