[Bugfix v4 0/2] Fix xen IRQ allocation failure caused by commit b81975eade8c

[Jiang Liu]

With more knowledge of Xen interrupt manangement subsytem, I realized
previous three versions to fix https://lkml.org/lkml/2014/12/19/178 are
just plainly wrong. Those patches try to fix the issue by creating
irqdomain for IOAPICs for PV domains, which effectively let native
IOAPIC driver and Xen PV interrupt management subsystem to manage
IOAPIC irqs concurrently, sounds unpredictable.

Sorry for those wrong fixes. The good news is that the new fix does
make code simpler and easier to maintain.

I have tested the patchset on Intel platform with bare metal and Dom0
kernels.

Hi Sander,
	Could you please help to test it again?

Regards!
Gerry
