Just got this from current 2.6 BK:
CC arch/ppc/boot/simple/misc.o
In file included from include/linux/elf.h:5,
from arch/ppc/boot/simple/misc.c:20:
include/asm/elf.h:102: warning: `struct task_struct' declared inside parameter list
include/asm/elf.h:102: warning: its scope is only this definition or declaration, which is probably not what you want
This can be cured by either including linux/sched.h or defining
struct task_struct;
(like this - maybe it should be more close to the headers)

Can you try just removing <linux/elf.h> from everything in
arch/ppc/boot/ ?

elf.h include is present in arch/ppc/boot/simple/misc.c and
arch/ppc/boot/simple/misc-embedded.c. The first one caused my warning
and the include can be safely removed from there. The other file is not
used in my config (prep) but I did try to compile it with elf.h include
removed (make arch/ppc/boot/simple/misc-embedded.o) and it failed. So
here is the patch against arch/ppc/boot/simple/misc.c. Nevertheless,
asm-ppc/elf.h can not be included by itself without a warning about
struct task_struct - is this a problem or not?

Ok, I'll look into that myself.

It depends on if (a) other arches have a task_struct-needing extern in
this file and (b) what do they do? There's at least a few #includes
with implicit #include requirements out there, i _think_.

I checked and I simply removed it when building for an ep8260. What
board still needs it?
