* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6: (179 commits) ACPI: Fix acpi_processor_idle and idle= boot parameters interaction acpi: fix section mismatch warning in pnpacpi intel_menlo: fix build warning ACPI: Cleanup: Remove unneeded, multiple local dummy variables ACPI: video - fix permissions on some proc entries ACPI: video - properly handle errors when registering proc elements ACPI: video - do not store invalid entries in attached_array list ACPI: re-name acpi_pm_ops to acpi_suspend_ops ACER_WMI/ASUS_LAPTOP: fix build bug thinkpad_acpi: fix possible NULL pointer dereference if kstrdup failed ACPI: check a return value correctly in acpi_power_get_context() #if 0 acpi/bay.c:eject_removable_drive() eeepc-laptop: add hwmon fan control eeepc-laptop: add backlight eeepc-laptop: add base driver ACPI: thinkpad-acpi: bump up version to 0.20 ACPI: thinkpad-acpi: fix selects in Kconfig ACPI: thinkpad-acpi: use a private workqueue ACPI: thinkpad-acpi: fluff really minor fix ACPI: thinkpad-acpi: use uppercase for "LED" on user documentation ... Fixed conflicts in drivers/acpi/video.c and drivers/misc/intel_menlow.c manually.
