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. Also fix the duplicated include reported by: Huang Weiyi Signed-off-by: Jason Wessel

drivers/misc/sgi-xp: clean up return values

2008-05-13T15:02:23Z

Make XP return values more generic to XP and not so tied to XPC by changing enum xpc_retval to xp_retval, along with changing return value prefixes from xpc to xp. Also, cleanup a comment block that referenced some of these return values as well as the handling of BTE related return values.
