The example I gave was GENERIC_CLOCKEVENTS on m68, which is
supported on most but not all machines there. This is also missing on
a couple of others (ia64 at least, not sure what else). Another one would
be having CLKDEV_LOOKUP without COMMON_CLK. This one is not
a problem for m68k but is for a couple of ARM and MIPS platforms
that have not yet been converted to COMMON_CLK.
There are probably a couple more like this. I don't actually see any that
are /only/ used by m68k, but there are some interfaces that would be
good to stop using overall to keep things simpler.
