A fix for this was merged by Linus prior to the release of 2.6.23-rc3.

Is there some special magic needed (like resubmit), or will you slurp this one
yourself?

This is already fixed in mainline
There is a real regression with failing builds on some old binutils on
x86-64 know, but I don't know how to fix it.

Yes. Anyways it be likely a WONT-FIX -- aka document newer binutils
version required. We haven't had any other reports so likely
that version is not too widely used.

IOW: Either the Linux binutils >= 2.17.50.0.3 or the not yet released
GNU binutils 2.18 are now required.
Debian 4.0 has older ones, and all distributions released more than a
year ago for sure also have older ones (the required patch went into
binutils CVS on 2006-05-30 and 2.17.50.0.3 was released on 2006-07-15).
Isn't that a bit too recent?

I have no problem on SUSE 10.0 (2.16.91.0.2-8) or SLES9 (2.15.90.0.1.1-32.10)
which are both far older than a year. Both produce good looking
vdso.sos.
sles8 (2.12.90.0.15; it was really one of the first production
binutils for x86-64) doesn't work out of the box (looks like as-instr doesn't
work anymore and it has another assembler issue I'll fix)
but with that workarounded it also builds a reasonble looking vdso
Sam, can you please take a look at the as-instr issue? It seems
to succeed now when it should fail.
It would be useful if someone could find out which binutils versions
really not work.

OK sorry, then I misunderstood it and missing -Wl,-z,max-page-size=4096
-Wl,-z,common-page-size=4096 support is not the problem.

We had several reports of 2.12* not working (AFAIR also on i386), so
that's not a surprise.

If Andre is working under Debian 3.1 (as his gcc version indicates) he's
using 2.15, and together with your SLES9 test it seems the border is
somewhere between 2.15 and 2.16.

It might be. The change to default to 1MB pages happened
some time ago and then the common-page-size options were
added some time after that.
I expect you'll get the obscenly large 1MB vdso if your
binutils happens to fall inside that time window, but before or
after should be ok.
I haven't tested it, but in theory a 1MB vdso should
work (just waste a lot of memory and probably some CPU time)
I was pondering to add a build time test for this and fail
(not sure it's worth it)
But the header offset problem that actually broke
the compilation seemed to be something else, probably
some sort of bug.

Ah I didn't see those. I should test it more often perhaps.
I'll take a detailed look later, perhaps it's easy to fix.

Could someone confirm? Then it could be documented.

Hi Andi.
I never got around to do any exhaustive check on as-instr.
I assume it was the .cfi_rel_offset thing that caused you to
assume as-instr was failing?
If not let me know if your request is still valid.
And sorry for being late on this. Busy and had forgotten this mail.
