Subject: tip tree allows nr_irqs to increase dynamically?

Hi Thomas,

It looks like tip.git irq/core contains patches to allow nr_irqs to
expand dynamically. Are these targeted at 2.6.39 or something later?

I'm working on some cleanups to Xen's irq handling and they will
require/interact with this new behaviour, is there a suitable commit
which I could consider for pulling into my tree to build upon?

Thanks,
Ian.

2.6.39

Unfortunately it's the original commit plus a fix which came way
later, so head of irq/core is the only choice.

That's fine. I'll keep you in the loop with any branches etc I publish
which incorporate this branch.
