* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6: (117 commits) ACPI processor: Fix section mismatch for processor_add() ACPI: Add platform-wide _OSC support. ACPI: cleanup pci_root _OSC code. ACPI: Add a generic API for _OSC -v2 msi-wmi: depend on backlight and fix corner-cases problems msi-wmi: switch to using input sparse keymap library msi-wmi: replace one-condition switch-case with if statement msi-wmi: remove unused field 'instance' in key_entry structure msi-wmi: remove custom runtime debug implementation msi-wmi: rework init msi-wmi: remove useless includes X86 drivers: Introduce msi-wmi driver Toshiba Bluetooth Enabling driver (RFKill handler v3) ACPI: fix for lapic_timer_propagate_broadcast() acpi_pad: squish warning ACPI: dock: minor whitespace and style cleanups ACPI: dock: add struct dock_station * directly to platform device data ACPI: dock: dock_add - hoist up platform_device_register_simple() ACPI: dock: remove global 'dock_device_name' ACPI: dock: combine add|alloc_dock_dependent_device (v2) ...
