Subject[RFC Patch V1 0/4] enhance IOAPIC core to support hotplug
Date
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
