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()
