[Qemu-devel] [PATCH v2 2/6] target-i386: Rename KVM auto-feature-enable compat function

[Eduardo Habkost]

The x86_cpu_compat_disable_kvm_features() name was a bit confusing, as
it won't forcibly disable the feature for all CPU models (i.e. add it to
kvm_default_unset_features), but it will instead turn off the KVM
auto-enabling of the feature (i.e. remove it from kvm_default_features),
meaning the feature may still be enabled by default in some CPU models).
