This series reworks the stackleak code. The first patch fixes some

improve clarity and permit better code generation.

This looks nice; thanks! I'll put this through build testing and get it
applied shortly...

While the improvement is small, I think the improvement to clarity and
code generation is a win regardless.

Agreed. I also want to manually inspect the resulting memory just to
make sure things didn't accidentally regress. There's also an LKDTM test
for basic functionality.

Hi Mark and Kees!

Glad to see this patch series.

I've looked at it briefly. Mark, I see your questions in the patches that I can answer.

Please give me some time, I'm going to work on your patch series next week. I'll return with review and testing.

Thanks!
Alexander
