Currently jprobe.entry is a kprobe_opcode_t *, but that's a lie. On some platforms it doesn't point to an opcode at all, it points to a function descriptor.
It's really a pointer to something that the arch code can turn into a function entry point. And that's what actually happens, none of the generic code ever looks at jprobe.entry, it's only ever dereferenced by arch code.
So just make it a void *.

It isn't obvious where kprobes patches should go, is anyone "the" maintainer? Instead I've just sent this to everyone who'd touched the code lately, or might be otherwise interested.
