Are any of these worth fixing?

Many of those warnings I have already fixed. I had posted quite a few
patches. Looks like some of these have not made into mainline yet.
For ex...

http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.20-rc6/2.6.20-rc6-mm3/broken-out/x86_64-mm-move-startup_32-in-texthead-section.patch

http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.20-rc6/2.6.20-rc6-mm3/broken-out/x86_64-mm-break-init-in-two-parts-to-avoid-modpost-warnings.patch

I think I should trace the status of all the patches I had posted.

Thanks
Vivek

The two part init / head.S patch was considered too intrusive late
in the game.
Near all of the other section patches should have made it in though.

Yes all others have gone in. I found one more which is present in rc-mm2, but
can't see it in rc6-mm3.

Andrew seems to have dropped it. Not sure why.

I commented it out in the series file because of clashes with git-acpi.
I'll bring it back (somehow) once Andi and Len have sorted things out.
