_cpu_down() acquires `workqueue_mutex' on its process, but doen't release it
if __cpu_disable() fails.

We need to assign resources to ioapics being hot-added. This patch
changes pbus_assign_resources_sorted() to assign resources if the
ioapic has no assigned resources.

Currently acpiphp calls pci_enable_device() against all
hot-added bridges, but acpiphp does not call pci_disable_device()
against them in hot-remove. So ioapic hot-remove would fail.
This patch fixes this issue.

Contrary to PCI bridge hot-add, we need to follow the sequence below
for PCI bridge hot-removal.
(1) Stop devices (detach drivers, remove from the global list, etc.)
(2) Unbind ACPI node from the devices (remove the _PRT entries)
(3) Remove devices (remove from the device list, etc.)
This patch fixes acpiphp driver to follow above sequence for P2P
bridge hot-removal.

This patch adds pci_stop_bus_device() which stops a PCI device (detach
the driver, remove from the global list and so on) and any children.
This is needed for ACPI based PCI-to-PCI bridge hot-remove, and it will
be also needed for ACPI based PCI root bridge hot-remove.

Currently acpiphp initializes all ioapics under the bus on which
hot-add event occured. It also initializes already working ioapics.

Currently acpiphp sets hpp values after starting devices, but
the values should be set before starting devices. This patch

This patch removes following compile time warnings:
drivers/pci/pci-sysfs.c: In function `pci_read_legacy_io':
drivers/pci/pci-sysfs.c:257: warning: implicit declaration of function `ia64_pci_legacy_read'
drivers/pci/pci-sysfs.c: In function `pci_write_legacy_io':
drivers/pci/pci-sysfs.c:280: warning: implicit declaration of function `ia64_pci_legacy_write'
It also fixes wrong definition of ia64_pci_legacy_write (type of `bus' is not
`pci_dev', but `pci_bus').
