The kernel is trying to fudge the section flags for .modinfo to prevent
.modinfo being loaded as part of a module. This works on older
toolchains, it even works on recent toolchains but now you get an
annoying warning. modutils >= 2.3.19 has special case code for
.modinfo so the kernel fudge is no longer required.
The 2.4 kernel will be patched to remove the warning in my next set of
module changes, probably 2.4.1. The 2.2 kernel will _not_ be patched
because that would force all 2.2 users to upgrade their user space
tools which is a no-no for 2.2. But if you have already upgraded your
user space tools, you can patch 2.2 linux/module.h yourself to remove
the warning. Against 2.2.18-pre27.

Re: warning during make modules
Is this a 2.4.0 issue? Because I see the warnings on 2.2.18
too, and also building alsa-driver. I use modutils 2.3.22.
binutils 2.10.1.0.2. glibc 2.2.
2.2.17 reported the same, 2.4.0-test11 too (but I never ran
this one).
The compiler is egcs 1.1.2. gcc is a symlink to egcs-2.1.96.

The patch is in the original email, reproduced below. It is against
linux-2.4.0-test12-pre7 but will fit -pre8 as well. The Kernel-HOWTO

Hi Keith,
Thanks for your reply. The below mentioned warning messages where displayed
while using modutils 2.3.22. Guess I need to apply the patch you mentioned
to removed all the anonying messages.
As I've not applied any patch before, pls advise where should I download the
patch and the instructions for patching pls.
Thanks.

You can safely ignore the messages. But if they get too annoying,
upgrade to modutils >= 2.3.19 (current is 2.3.22) and apply this patch.

Is this a 2.4.0 issue? Because I see the warnings on 2.2.18
too, and also building alsa-driver. I use modutils 2.3.22.
binutils 2.10.1.0.2. glibc 2.2.
2.2.17 reported the same, 2.4.0-test11 too (but I never ran
this one).
The compiler is egcs 1.1.2. gcc is a symlink to egcs-2.1.96.
