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 You may pull from https://github.com/jiangliu/linux.git ioapic/hotplug Once passed review, we will use Yinghai's patches to glue IOAPIC driver and ACPI PCI root driver to handle hotplug events.
