Subject[patch 25/41] ACPI: Attach the ACPI device to the ACPI handle as early as possible
2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Zhao Yakui <yakui.zhao@intel.com>

commit eab4b645769fa2f8703f5a3cb0cc4ac090d347af upstream.

Attach the ACPI device to the ACPI handle as early as possible so that OS
can get the corresponding ACPI device by the acpi handle in the course
of getting the power/wakeup/performance flags.
