Re: [libvirt] [PATCH 04/36] cpu_x86: Do not cache microcode version

The microcode version checks are used to invalidate cached CPU data we get from QEMU. To minimize /proc/cpuinfo parsing the microcode version was only read when libvirtd started and cached for the daemon's lifetime. However, the CPU microcode can change anytime (updating the microcode package can automatically upload it to the CPU) and we need to stop caching it to avoid using stale CPU model data.
