commit f14413184b1de4dcbd5ec3e7c129c3ce2079f543 upstream Date: Wed, 20 Aug 2008 14:08:57 -0700 Subject: eeepc-laptop: fix use after free eeepc-laptop uses the hwmon struct after unregistering the device, causing an oops on module unload. Flip the ordering to fix.

acer-wmi: Fix wireless and bluetooth on early AMW0 v2 laptops

2008-08-20T18:05:03Z

commit 5c742b45dd5fbbb6cf74d3378341704f4b23c5e8 upstream In the old acer_acpi, I discovered that on some of the newer AMW0 laptops that supported the WMID methods, they don't work properly for setting the wireless and bluetooth values. So for the AMW0 V2 laptops, we want to use both the 'old' AMW0 and the 'new' WMID methods for setting wireless & bluetooth to guarantee we always enable it. This was fixed in acer_acpi some time ago, but I forgot to port the patch over to acer-wmi when it was merged. (Without this patch, early AMW0 V2 laptops such as the Aspire 5040 won't work with acer-wmi, where-as they did with the old acer_acpi).

thinkpad-acpi: fix LED handling on older ThinkPads

2008-06-11T23:13:45Z

The less tested codepaths for LED handling, used on ThinkPads 570, 600e/x, 770e, 770x, A21e, A2xm/p, T20-22, X20 and maybe a few others, would write data to kernel memory it had no business touching, for leds number 3 and above. If one is lucky, that illegal write would cause an OOPS, but chances are it would silently corrupt a byte. The problem was introduced in commit af116101, "ACPI: thinkpad-acpi: add sysfs led class support to thinkpad leds (v3.2)". Fix the bug by refactoring the entire code to be far more obvious on what it wants to do. Also do some defensive "constification". Issue reported by Karol Lewandowski (he's an lucky guy and got an OOPS instead of silent corruption :-) ). Root cause of the OOPS identified by Adrian Bunk . Thanks, Adrian!

thinkpad-acpi: fix initialization error paths

2008-06-11T23:13:45Z

Rework some subdriver init and exit handlers, in order to fix some initialization error paths that were missing, or broken. Hitting those bugs should be extremely rare in the real world, but should that happen, thinkpad-acpi would fail to dealocate some resources and a reboot might well be needed to be able to load the driver again.

kgdbts: Use HW breakpoints with CONFIG_DEBUG_RODATA

2008-05-28T17:49:57Z

Whenever CONFIG_DEBUG_RODATA is set in the kernel config many kernel text sections become read-only, and the use of software breakpoints in the kgdb tests will cause the kernel to fail to complete the start up. Until such time that there is an official API for modifying read-only text sections hardware breakpoints must be used to run the do_fork or sys_open tests or the tests get skipped.
