The resulting kernel hasn't broken on me yet, however.

A search through the LKML archives showed that this was reported
for 2.6.25-rc3-mm1, but I couldn't find any discussion about it
after that:

<http://marc.info/?l=linux-kernel&m=120470303728010&w=2>

The .config causing this warning is available in
<http://user.it.uu.se/~mikpe/linux/ale/config-2.6.26-rc1>


This is because the organization of the file was changed, and the linker script wasn't changed to match:

SECTIONS
{
. = HEADER_OFFSET;
.header : {
*(.header)
}

. = 0;
.text : {
*(.text*)
}

This is crap; the sections should be listed *in order* so the linker can warn properly when something bad happens.

The code should be correct; reorganizing the linker script correctly should fix the problem.
