[libvirt] [PATCH qom-cpu 0/7] disable kvm_mmu + -cpu "enforce" fixes (v3)

Changes on v3: - Patches 3-9 from v2 are now already on qom-cpu tree - Remove CONFIG_KVM #ifdefs by declaring fake KVM_* #defines on sysemu/kvm.h - Refactor code that uses the feature word arrays (to make it easier to add a new feature name array) - Add feature name array for CPUID leaf 0xC0000001 Changes on v2: - Now both the kvm_mmu-disable and -cpu "enforce" changes are on the same series - Coding style fixes Git tree for reference: git://github.com/ehabkost/qemu-hacks.git cpu-enforce-all.v3 https://github.com/ehabkost/qemu-hacks/tree/cpu-enforce-all.v3 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.
