Merge remote-tracking branch 'afaerber/qom-cpu' into staging

* afaerber/qom-cpu:
  target-i386: Use switch in check_hw_breakpoints()
  target-i386: Avoid goto in hw_breakpoint_insert()
  target-i386: Introduce hw_{local,global}_breakpoint_enabled()
  target-i386: Define DR7 bit field constants
  target-i386: Move kvm_check_features_against_host() check to realize time
  target-i386: cpu_x86_register() consolidate freeing resources
  target-i386: Move setting defaults out of cpu_x86_parse_featurestr()
  target-i386: check/enforce: Check all feature words
  target-i386/cpu.c: Add feature name array for ext4_features
  target-i386: kvm_check_features_against_host(): Use feature_word_info
  target-i386/cpu: Introduce FeatureWord typedefs
  target-i386: Disable kvm_mmu by default
  kvm: Add fake KVM constants to avoid #ifdefs on KVM-specific code
  exec: Return CPUState from qemu_get_cpu()
  xen: Simplify halting of first CPU
  kvm: Pass CPUState to kvm_init_vcpu()
  cpu: Move cpu_index field to CPUState
  cpu: Move numa_node field to CPUState
  target-mips: Clean up mips_cpu_map_tc() documentation
  cpu: Move nr_{cores,threads} fields to CPUState
