cpuidle is currently optional, that is why the two level hierarchy
is there so that you can still have simple idle selection without it.
% size drivers/cpuidle/*.o
text data bss dec hex filename
5514 1416 44 6974 1b3e drivers/cpuidle/built-in.o
Adding it unconditionally would add ~7k to everyone who wants idle functions.
I think making it unconditional would require putting it on a serious
ak at linux.intel.com -- Speaking for myself only.
