This commit was manufactured to restore the state of the 6.0-RELEASE image.

MFC Rev. 1.8:

  Don't lock when holding led_mtx, instead use AcpiOsQueueForExecution to defer
  the locking.

  Idea taken from: acpi_asus(4)

Add the ID of my Thinkpad R40. Makes the module detect and with the

exception of fans everything seems to work fine.  No ill effects
observed.

- Only create the led(4) interface, if setting the thinklight is possible

- Initialize val_ec with the content of the volume EC register
  for ACPI_IBM_METHOD_VOLUME and ACPI_IBM_METHOD_MUTE in acpi_ibm_sysctl_set()
  if there is no CMOS handle present. This fixes setting volume and mute on
  such models.

Import a mostly rewritten and extended version of acpi_ibm:

2005-06-09T20:17:32+00:00

- Restructured for easier extensibility and maintainability
- To be more uniform with the other ACPI extras drivers and to better reflect
  their actual meaning, some sysctls were moved:
    o brightness -> lcd_brightness
    o keylight   -> thinklight
    o enable     -> events
    o misckey    -> hotkey
    o avail_mask -> availmask
    o key_mask   -> eventmask
- New "initialmask" sysctl, which holds the initial eventmask
- The "wlan" sysctl is now read-only, since writing to it didn't have
  any effect
- The "version" sysctl was removed, since it seems to be the same (0x100)
  on all models I have seen
- Support for more hotkeys by the "hotkey" sysctl
- Improved support of ACPI events. Disabled by default, since it unexpectedly
  changes the behaviour of some keys. (on my T41p there are now 24 different
  keypress events that get reported)
- write support for: volume, mute, lcd_brightness and thinklight
- led(4) interface for the thinklight [1]
- New sysctls "fan" and "fan_speed" to support reading of fan status and speed
- New sysctl "thermal" to support reading of up to 8 thermal sensors

Unify ACPI_DEBUG support for all OEM drivers under ACPI_OEM. Since more than

2004-12-13T23:31:46+00:00

one will never be supported on the same platform, this does not hurt
debugging.

MFC after:	3 days

Allow the acpi_ibm module to be built with ACPI_DEBUG.

Add IBM Laptop extra device driver.

This depends on ACPI and RTC registers.
