We have two reports of drivers broken in v4.3 by Jiang's change,
991de2e59090 ("PCI, x86: Implement pcibios_alloc_irq() and
pcibios_free_irq()").
It would be best to fix the problem instead of reverting 991de2e59090, but
I don't have time to do that myself, and we haven't heard from Jiang, so
the only choice I have is to revert the commit.
Note that reverting will likely break IOAPIC hotplug.
I haven't put my signed-off on it yet because it didn't revert cleanly, and
I'm not sure that I did it correctly.
Олег and Sunjin, can you please test this and see whether it fixes your
drivers? This patch is based on v4.5-rc1.
