FWIW, I did a build and boot test in a hyperv guest with your
development branch, the latest commit is 71cbf478eb6f ("irqchip: Add
IMS (Interrupt Message Storm) driver - NOT FOR MERGING"). And everything
seemed working fine.

If you want me to set/unset a particular CONFIG option or run some
command for testing purposes, please let me know ;-)
