Cover letter [RFC Patch V1 0/4] enhance IOAPIC core to support hotplug
This patch set enhances IOAPIC core to support IOAPIC hotplug on x86 platforms. It's based on another patch set "use irqdomain to dynamically allocate IRQ for IOAPIC" at https://lkml.org/lkml/2014/5/27/86

Once passed review, we will use Yinghai's patches to glue IOAPIC driver and ACPI PCI root driver to handle hotplug events.
