Hi Alexey,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on tip/irq/core]
[also build test ERROR on linus/master linux/master v5.10-rc4 next-20201120]
[If your patch is applied to the wrong git tree, kindly drop us a note.

What is the easiest way to get irq-hierarchical hardware?
I have a bunch of powerpc boxes (no good) but also a raspberry pi,
a bunch of 32/64bit orange pi's, an "armada" arm box,
thinkpads - is any of this good for the task?
If your HW doesn't

I'll try to go through this patch over the week-end (or more probably
early next week), and try to understand where our understandings
differ.
Great, thanks! Fred spotted a problem with irq_free_descs() not doing
kobject_put() anymore and this

PCI devices share 4 legacy INTx interrupts from the same PCI host bridge.
Device drivers map/unmap hardware interrupts via irq_create_mapping()/
irq_dispose_mapping(). The problem with that these interrupts are
shared and when performing hot unplug, we need to unmap the interrupt
only when the
