Wow, that saved me a lot of time. I just ran into the same issue and was
close to getting mad over the effect.

Maybe the commit is only that big because cvs-to-git conversion merged
too much into a single commit. I can't imagine that such a huge change
is done in one step.

At least it is a critical one as it makes kernel module debugging nearly
impossible. I'm preparing a LinuxCon talk about how cool kernel
debugging with gdb and qemu can be - looks like I have to skip this
part... ;)

If there is anything to be done that could help analyzing the issue,
please let us know.
