* remotes/afaerber/tags/qom-cpu-for-2.1:
  target-i386: Broadwell CPU model
  target-i386: Fix indentation of CPU model definitions
  target-i386: Support "invariant tsc" flag
  target-i386: block migration and savevm if invariant tsc is exposed
  savevm: check vmsd for migratability status
  target-i386: Set migratable=yes by default on "host" CPU mooel
  target-i386: Add "migratable" property to "host" CPU model
  target-i386: Support check/enforce flags in TCG mode, too
  target-i386: Loop-based feature word filtering in TCG mode
  target-i386: Loop-based copying and setting/unsetting of feature words
  target-i386: Define TCG_*_FEATURES earlier in cpu.c
  target-i386: Filter KVM and 0xC0000001 features on TCG
  target-i386: Filter FEAT_7_0_EBX TCG features too
  target-i386: Make TCG feature filtering more readable
  target-i386: Isolate KVM-specific code on CPU feature filtering logic
  target-i386: Pass FeatureWord argument to report_unavailable_features()
  target-i386: Merge feature filtering/checking functions
  target-i386: Simplify reporting of unavailable features
  target-i386: kvm: Don't enable MONITOR by default on any CPU model
