> After a recent change present in 3.11-rc1 there is a driver, called processor, 
> that can be bound to the CPU devices whose sysfs directories are located under 
> /sys/devices/system/cpu/. A side effect of this is that, after the driver has 
> been bound to those devices, the kernel adds DRIVER=processor to ENV for CPU
> uevents and they don't match the default rule for autoloading modules matching 
> MODALIAS: 
> 
> DRIVER!="?*", ENV{MODALIAS}=="?*", IMPORT{builtin}="kmod load $env{MODALIAS}" > 
> any more. However, there are some modules whose module aliases match specific 
> CPU features through the modalias string and those modules should be loaded 
> automatically if a compatible CPU is present. Yet, with the processor driver 
> bound to the CPU devices the above rule is not sufficient for that, so we need 
> a new default udev rule allowing those modules to be autoloaded even if the 
> CPU devices have drivers.
