jprobes: make struct jprobe.entry a void *
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 *.
