The paragraph about i386 could be misinterpreted as if 386 still is a
valid processor type. Mention when 386 support ended, and change two
"arch/i386/" paths to one that exists, "arch/x86/".

So we want the documentation to reflect current kernels, not those from
years gone by. I can't think of a reason why this paragraph should
continue to exist at all. Can you make a new version that removes it
altogether?
Thanks,
jon

That was also my first thought, yes. But then I thought, maybe there's
some value to that information in case someone wants to try a new kernel
on some ancient hardware. But it's probably an unlikely scenario. I'll
send a new patch now.

You may want to generalize it to "will not boot if you se processor
type too high", but I'd keep v3.7 note -- it is going to be tricky to
find out in any other way.
Best regards,
Pavel
