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? "Help us, Obi-wan Weisbecker.
