Currently it only is possible to install one system notify handler
per namespace node, but this is not enough for PCI run-time power
management, because we need to install power management notifiers for
devices that already have hotplug notifiers installed. While in
principle this could be handled at the PCI level, that would be
suboptimal due to the way in which the ACPI-based PCI hotplug code is
designed.
For this reason, modify ACPICA so that it is possible to install more
than one system notify handler per namespace node. Namely, make
acpi_install_notify_handler(), acpi_remove_notify_handler() and
acpi_ev_notify_dispatch() use a list of system notify handler objects
associated with a namespace node.
Make acpi_remove_notify_handler() call acpi_os_wait_events_complete()
upfront to avoid a situation in which concurrent instance of
acpi_remove_notify_handler() removes the handler from under us while
we're waiting for the event queues to flush.

ACPI GPEs may map to multiple devices. The current GPE interface
only provides a mechanism for enabling and disabling GPEs, making
it difficult to change the state of GPEs at runtime without extensive
cooperation between devices.
Add an API to allow devices to indicate whether or not they want
their device's GPE to be enabled for both runtime and wakeup events.
Remove the old GPE type handling entirely, which gets rid of various
quirks, like the implicit disabling with GPE type setting. This
requires a small amount of rework in order to ensure that non-wake
GPEs are enabled by default to preserve existing behaviour.
Based on patches from Matthew Garrett <mjg@redhat.com>.

Add 2010 copyright to all module headers and signons, including
the Linux header. This affects virtually every file in the ACPICA
core subsystem, iASL compiler, and all utilities.

This change deletes the unnecessary acpi_ns_convert_entry_to_handle
interface and renames the acpi_ns_map_handle_to_node interface to
acpi_ns_validate_handle. ACPICA BZ 798.
