I took a stab at it. It wasn't too bad, although I think this needs a
*lot* of testing, and I think it needs checking of Makefile
dependencies etc.

NOTE NOTE NOTE! This may be *COMPLETELY* broken. It just happens to
build for me.  So when I say "it wasn't too bad", I really mean "it
wasn't too bad, but I didn't spend a lot of effort on it either".

Honestly, the code is better and more legible without gperf, imho. And
it removes more lines than it adds - and even if you ignore changes to
the shipped lines, it's only an additional 15 lines of code,

It's likely not even any slower, but who the hell knows.. Do we even
care? It's almost certainly faster if you compare to generating that
gperf code.

Patch

From bb3290d91695bb1ae78ab86f18fb4d7ad8e5ebcc Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@linux-foundation.org>
Date: Sat, 19 Aug 2017 10:17:02 -0700
Subject: [PATCH] Remove gperf usage from toolchain

It turns out that gperf-3.1 changed types in the generated code in ways
that aren't even trivially detectable without having to generate a test-file.

It's just not worth using tools and libraries from clowns that don't
understand or care about compatibility.  So get rid of gperf.
