Sorry, I was imprecise.  I was referring to the kernel's kallsyms
tables produced by scripts/kallsyms.c.  This patch left them in the
the kallsyms tables and filtered them out from /proc/kallsyms.

Yes, but it isn't easy to do it by script/kallsyms.c , and IMO, it should
be correct to hide them for user space but keep them in kallsyms table.

So they'll appear in backtraces?  And turn up randomly for other symbol
dereferences?

I don't think you really want this!

It's weird that cpu_v7_suspend_size appeared above, since kallsyms
should filter out 'A' symbols already.

Sorry, the 'A' symbol is a mistake, but the others do exist in /proc/kallsyms.

Ah, OK.

Cheers,
Rusty.
