The mapping consists of three new symbols

The entire commit log does not describe *why*.

... because it's in the other commit logs and the cover letter. I can
repeat the motivation in this log too if you like.

Can I also trouble you to rebase on top of modules-next [0]

Sure!

Does the kallsyms loop more than 3 times now with Zhen Lei's work and
your new symbols on top on a allyesconfig build?

I don't understand the question, sorry. If this is about the number of
KALLSYMS invocations in the kernel build, that should be unchanged by
this patch. This was an explicit design goal because it's quite slow to
run kallsyms more times and I was already feeling guilty about having to
bring back the tristate recursion.

I haven't tried it with Zhen Lei's work: will try for the next
iteration, as a matter of course after the rebase. (And, looking at the
patch series at the top of modules-next, wow is that quite a hefty
performance improvement. And a hefty memory usage increase :( I have a
horrible feeling that one of my machines won't have enough memory to
boot after this goes in, but it was terribly outdated anyway.)

It's only about 500K. It shouldn't be a problem. Your machine boot from flash?
