Merge remote-tracking branch 'qemu-kvm/uq/master' into staging

* qemu-kvm/uq/master:
  pc-bios: update kvmvapic.bin
  kvmvapic: Use optionrom helpers
  optionsrom: Reserve space for checksum
  kvmvapic: Simplify mp/up_set_tpr
  kvmvapic: Introduce TPR access optimization for Windows guests
  kvmvapic: Add option ROM
  target-i386: Add infrastructure for reporting TPR MMIO accesses
  Allow to use pause_all_vcpus from VCPU context
  Process pending work while waiting for initial kick-off in TCG mode
  Remove useless casts from cpu iterators
  kvm: Set cpu_single_env only once
  kvm: Synchronize cpu state in kvm_arch_stop_on_emulation_error()
