This patch set enhances IOAPIC core and ACPI drivers to support IOAPIC
hotplug on x86 platforms. It's based on tip/x86/apic.

You may pull it from 
https://github.com/jiangliu/linux.git ioapic/hotplug_v3

We have pick up several patches from Yinghai's original IOAPIC hotplug
patch set and reimplemented IOAPIC driver as an ACPI driver instead of
a PCI driver.

It has been tested on a 4-socket Intel SDV with socket hot-addition
capability. Any suggestions are welcomed!

Patch 1-5 are minor bugfixes and code improvements
Patch 6-14 enhances ACPI and IOAPIC core to support IOAPIC hotplug
Patch 15 killes PCI IOAPIC driver
Patch 16 reimplements ACPI IOAPIC driver and enables IOAPIC hotplug

V2->V3:
1) Refine ACPI resource walk functions for PCI root bus and IOAPIC
2) Improve commit messages
3) Reorder patch order for better maintenence

Jiang Liu (11):
  x86, irq, ACPI: Protect acpi_pci_irq_enable() from reentrance
  ACPI: Correct return value of acpi_dev_resource_address_space()
  x86, PCI, ACPI: Kill private function resource_to_addr()
  x86, irq: Remove __init marker for functions will be used by IOAPIC
    hotplug
  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
  x86, irq: Introduce helper to check whether an IOAPIC has been
    registered
  PCI: Remove PCI ioapic driver
  x86, irq, ACPI: Implement ACPI driver to support IOAPIC hotplug

Yinghai Lu (5):
  ACPI: Make map_mat_entry handle x2apic entry
  ACPI: Move acpi_get_cpuid() to separated file
  x86, irq: Split out alloc_ioapic_save_registers()
  x86, ioapic: Find usable ioapic id for 64bit.
  ACPI, ioapic: Add acpi_get_ioapic_id()
