When CONFIG_DEBUG_INFO is unset the input .exit.data sections are copied
twice to vmlinux. Remove the copy made to .init.text and keep one in
.data only.

It looks like an accidental mistake to me. It applies to current Linus's
2.6.23.
Please consider,
Maciej

No, they aren't. I believe the linker only makes one copy of each section,
and once a copy is inserted, all other attempts to make a copy of it are
ignored.
NAK.

Fair enough -- a quick test shows you are right. Wouldn't it deserve a
comment, though? I know hardly anybody dares looking into these scripts,
;-) but those who do, may not be sure this setup is intentional.
