KVM: x86: Move TSC scaling logic out of call-back read_l1_tsc()
Both VMX and SVM scales the host TSC in the same way in call-back read_l1_tsc(), so this patch moves the scaling logic from call-back read_l1_tsc() to a common function kvm_read_l1_tsc(). Signed-off-by: Haozhong Zhang <haozhong.zhang@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
