I mentioned this on lkml (with cc to Ingo and Peter), and Peter has a further patch that fixes the problem, which isn't in this pull. So Linus, please don't do this pull just yet, until we get this extra patch merged.

The actual kernel still grew: 32 files changed, 1327 insertions(+), 964 deletions(-) oh well. Merged anyway.

That was Ingo's forward looking investments, which I decided to take off the balance sheet not to get the IMF on our backs, glad you noticed the trick, never the less, it was at least a step on the right direction, I guess. > The actual kernel still grew: > > 32 files changed, 1327 insertions(+), 964 deletions(-) > > oh well.
