Intel regularly releases microcode updates and distributions are supposed to do
regular package updates with the latest microcode file. You should
get those with your normal update mechanism.
In general it's recommended to run with the latest microcode.
With the latest mainline kernel the microcode driver should be automatically
loaded by CPUID probing through udev.
