Currently all avr32 and sparc64 don't support kretprobes unlike all
other kprobes supporting architectures. This is not nice from the
user interface point of view and from the ugly ifdefs point of view.
Is there a reason these ports can't support kretprobes or was this
simply an oversight / lazyness?

I just haven't gotten around to it yet.
Don't worry I'm aware of it. :-)

Lazyness on my part, I guess. It shouldn't be too hard to implement on
avr32; It looks like the generic code sets a breakpoint on function entry,
so all I have to do is to set a breakpoint on the return address. And
handle the breakpoint somehow. I'll try to implement it when I get back to
work in about a week.
