This exports x86 CPUID information (features, vendors, models etc.) in a way that udev can autoprobe modules, similar to how USB or PCI devices are autoloaded. This allows to easily add CPU specific modules without requiring distributions to have special case init scripts. The biggest difference compared to the old version is that it hangs off the cpuid devices now, now the cpu devices. cpu devices were sysdevs which don't have all the infrastructure needed for udev. cpuid has all this so it works much better. This requires the cpuid driver to be loaded or builtin for the autoprobing to work. Any testing appreciated -Andi
