Well, cleaner.

You lost the leXX_to_cpu() part, so now it does the wrong thing if you
were to cross-build the tooling side on a BE architecture.

The actual kernel side is fine, of course, since it runs on x86 by definition.

So it's purely the tool side - I assume this instruction decoding is
used for objtool or something.

I'm not sure that matters. BE is dead, nobody would ever cross-build
tooling that way. But maybe a compile-time error, at least, so that
the problem is obvious.
