Hi Andrew,
The kgdb seems to be broken on the powerpc, while compiling with
allyesconfig.

I am not exactly sure how to fix this...
Another git tree is overriding the patch to include/asm-powerpc/kgdb.h
in the -mm tree. The patches as I provide them against 2.6.23-rc6 for
KGDB work correctly for ppc/powerpc in 32 and 64 bit modes and compile
correctly.
At issue is that someone merged a bogus copy of asm-ppc/kgdb.h from the
git tree in -mm that is called: git-powerpc.patch.

Yeah, this was pointed out and largely ignored.
I'm afraid you'll have to wait until that powerpc stuff hits mainline
and then fix it all up.

I could remove all the kgdb support from arch/powerpc as a first step,
if that would make it easier to pull in the new stuff...

I don't know if/when the new stuff will be merged - it's missed 2.6.24.
It might be better to proceed as you intended. Presumably it won't be too
hard to hack things back into shape.

Given that the existing powerpc kgdb bits didn't seem to work at all when
I tried them that seems like a perfectly fine thing to do.

Hi Paul,
The kgdb is also broken with 2.6.23-rc8-mm2 on the powerpc .
The below patch disables the kgdb from getting compiled over
powerpc platform.

This enables the KGDB config for _ALL_ platforms except powerpc.
Just remove PPC completely.
