This patch depends on SMP patch which I posted before. fix ptc.ga virtualization. Uninitialized vcpu doesn't need tlb flush. ptc_ga_remote_func() calls vmx_vcpu_ptc_l() in IPI context. I.e. vcpu may not equal to current. On the other hand vmx_vcpu_ptc_l() assumes vcpu = current. remove the assumption. -- yamahata
