[libvirt] [PATCH 0/9] target-i386: make "enforce" flag work as it should



This changes the -cpu check/enforce code to work as it should: it will
check every single CPUID bit to make sure it is supported by the host.

The changes are a bit intrusive, but:

 - The longer we take to make "enforce" strict as it should (and make libvirt
   finally use it), more users will have VMs with migration-unsafe unpredictable
   guest ABIs. For this reason, I would like to get this into QEMU 1.4.
 - The changes in this series should affect only users that are already using
   the "enforce" flag, and I believe whoever is using the "enforce" flag really
   want the strict behavior introduced by this series.

This series is based on Andreas' qom-cpu branch, and depends on the series:
  Subject: [PATCH 0/2] Disable kvm_mmu_op by default on pc-1.4
