Subject: Re: 2.6.23-rc6-mm1 powerpc - kgdb is broken

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.

Jason.
