Linus Torvalds 08acd4f8af Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6
* '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.
