Yeah - and that build bug was stupid too - when touching a generic file 
that is called include/linux/cpufreq.h and changing a key data field one 
should at minimum get the idea that it's generic for a reason and should 
start grepping the tree ...

It slipped through because it didnt get caught in build tests because 
cpufreq isnt enabled in the powerpc defconfig.
