  KVM: check injected pic irq within valid pic irqs
  KVM: x86 emulator: Fix HLT instruction
  KVM: Apply the kernel sigmask to vcpus blocked due to being uninitialized
  KVM: VMX: Add ept_sync_context in flush_tlb
  KVM: mmu_shrink: kvm_mmu_zap_page requires slots_lock to be held
  x86: KVM guest: make kvm_smp_prepare_boot_cpu() static
  KVM: SVM: fix suspend/resume support
  KVM: s390: rename private structures
  KVM: s390: Set guest storage limit and offset to sane values
  KVM: Fix memory leak on guest exit
  KVM: s390: dont allocate dirty bitmap
  KVM: move slots_lock acquision down to vapic_exit
  KVM: VMX: Fake emulate Intel perfctr MSRs
  KVM: VMX: Fix a wrong usage of vmcs_config
