kallsyms returns the first symbol encountered, even though it is weak,

Is it a concern for anyone else out there ? Would it make sense to fix
it ?
I don't know if it is a concern, but if we're going to fix it, we should
probably do it in "scripts/kallsyms" by providing a list that is already
sorted according to "address, weakness".
This way the run-time kernel keeps the current behavior, without any
overhead. Something along the lines of the attached patch (just compile
tested).
However, this is an area where we've had problems in the past with some
architectures giving different results between passes, and then any change
to the symbol order might make the problem worse and make the build process
fail with a "Inconsistent kallsyms data" error message.
So, if someone wants to use this, it should go through -mm for a while,
first.
It applies on top of 2.6.24-rc2-git3.
Please use this reply with correct CC list for further discussion.
I've been wanting to send this as a proper patch request email, but I
just hadn't found the time to do it, and then our mail server just went
berserk and I lost 5 days of LKML :P
I think the patch is ok as it is, but a nice message explaining what it
does and why would be nice for the changelog. So, I'll post a new
message with a nice description for inclusion in -mm today.
Sorry for the delay,
