Non-KVM folks,
I am hoping to route this through the KVM tree (6.17 or later), as the non-KVM changes should be glorified nops. Please holler if you object to that idea.
Hyper-V folks in particular, let me know if you want a stable topic branch/tag, e.g. on the off chance you want to make similar changes to the Hyper-V code, and I'll make sure that happens.

Applied to kvm-x86 irqs, thanks!
