* 'kvm-updates/2.6.33' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  KVM: x86: Fix leak of free lapic date in kvm_arch_vcpu_init()
  KVM: x86: Fix probable memory leak of vcpu->arch.mce_banks
  KVM: S390: fix potential array overrun in intercept handling
  KVM: fix spurious interrupt with irqfd
  eventfd - allow atomic read and waitqueue remove
  KVM: MMU: bail out pagewalk on kvm_read_guest error
  KVM: properly check max PIC pin in irq route setup
  KVM: only allow one gsi per fd
  KVM: x86: Fix host_mapping_level()
  KVM: powerpc: Show timing option only on embedded
  KVM: Fix race between APIC TMR and IRR
