From 07c1419a32bbba08cf1efb6d1ecaf24f174fa4c3 Mon Sep 17 00:00:00 2001 From: Haozhong Zhang Date: Tue, 20 Oct 2015 15:39:05 +0800 Subject: KVM: x86: Replace call-back compute_tsc_offset() with a common function Both VMX and SVM calculate the tsc-offset in the same way, so this patch removes the call-back compute_tsc_offset() and replaces it with a common function kvm_compute_tsc_offset().
