Ack on the whole series.

I guess x86-64 and powerpc no longer care, but for other architectures
the stack usage issue can be a regression even if I think it's only
been reported on Power. So I'm assuming we should pull this into 3.12.
Yes?

And what about earlier stable kernels? Afaik this was originally
introduced by commit facd8b80c67a, merged into 3.9. Or was there some
other trigger? Do we want to just do the "__do_softirq" ->
"do_softirq()" change for stable?
