This commit breaks all non-x86 architectures by adding a reference to
regs->flags in generic code. 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.
