[Qemu-devel] [PATCH 5/9] target-i386: Move warning code outside x86_cpu_filter_features()

[Eduardo Habkost <ehabkost@redhat.com>]

x86_cpu_filter_features() will be reused by code that shouldn't
print any warning. Move the warning code to a new
x86_cpu_report_filtered_features() function, and call it from
x86_cpu_realizefn().
