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.
Jiang Liu (4): x86, irq: refine mp_register_ioapic() to prepare for IOAPIC hotplug x86, irq, ACPI: introduce a rwsem to protect IOAPIC operations from hotplug x86, irq, ACPI: implement interface to support ACPI based IOAPIC hot-addition x86, irq, ACPI: implement interface to support ACPI based IOAPIC hot-removal
