And those cleanups make the compiler generate worse code at least on
x86_64:

   text	     data      bss      dec     hex    filename
   7475	     554       0	8029	1f5d   kernel/hrtimer.o
   7706	     554       0	8260	2044   kernel/hrtimer.o

So just removing parameters and return values because you can get the
same information from a datastructure is not necessarily a good thing.

Thanks,
