[Qemu-devel] [PATCH v3 3/5] target-i386: Define CPUID filtering function


From: Eduardo Habkost
Subject: [Qemu-devel] [PATCH v3 3/5] target-i386: Define CPUID filtering functions before x86_cpu_list()
Date: Mon, 19 Sep 2016 16:42:53 -0300

Just move code to another place so the it can be reused by the
query-cpu-definitions code.
