As I understand it /proc/cpuinfo is intended only for
humans to read. Please don't write code to parse it;
find a different way to get this information instead
if you really need it.

(I'm not really happy about such specific-to-a-particular-vendor
patches in QEMU anyway; we should have migration code that
works acceptably for any implementation.)
