'struct dmi_system_id' arrays must always have a terminator to keep dmi_check_system() from looking at data (and possibly crashing) it isn't supposed to look at. The issue went unnoticed until ef8313bb, but was introduced about a year earlier with 7705d548 (which also similarly changed lifebook.c, but the problem there got eliminated shortly afterwards). The first hunk therefore is a stable candidate back to 2.6.33, while the full change is needed only on 2.6.38. Signed-off-by:

Some devices provide absolute axes with min/max of 0/0 (e.g. wacom's ABS_MISC axis). Current uinput restrictions do not allow duplication of these devices and require hacks in userspace to work around this. If the kernel accepts physical devices with a min/max of 0/0, uinput shouldn't disallow the same range. Signed-off-by:

Touch resolution is reported to the userland by retrieving the value from the HID descriptor. But pen resolution is not since it can not be retrieved. The current Wacom X driver has a resolution table. To centralize the source of these values, the resolution entries are added in the wacom_features struct for x and y coordinates respectively. The values are then reported to the userland. Signed-off-by:

Commit 0b950d3d (Input: tsc2005 - add open/close) introduced a locking issue with the ESD watchdog: __tsc2005_disable() is calling cancel_delayed_work_sync() with mutex held, and the work also needs the same mutex. Fix the problem by using mutex_trylock() in tsc2005_esd_work(). If the mutex is taken, we know we are in the middle of disable or enable and the watchdog check can be skipped. Signed-off-by:

I believe that enable/disable functionality should not be implemented on the individual driver level but rather in device core, potentially reusing parts of PM framework. Therefore the driver-specific "disable" attribute is removed from the mainline driver. Tested-by:

Introduce open and close methods for the input device to keep the device powered down when it is not in use. Also rework interaction between interrupt thread and starting/shutting off/resetting the device: instead of taking a mutex in the intterrupt thread and elsewhere disable interrupts before transitioning the device in a new state. The ESD handling is also separated from the IRQ thread; we poll regularly at a given interval and simply skip reads if we see that valid interrupt happened not so long ago. This allows us not cancel and reschedule ESD work from interrupt context all the time. Tested-by:

A virtualized display device is usually viewed with the vncviewer application, either by 'xm vnc domU' or with vncviewer localhost:port. vncviewer and the RFB protocol provides absolute coordinates to the virtual display. These coordinates are either passed through to a PV guest or converted to relative coordinates for a HVM guest. A PV guest receives these coordinates and passes them to the kernels evdev driver. There it can be picked up by applications such as the xorg-input drivers. Using absolute coordinates avoids issues such as guest mouse pointer not tracking host mouse pointer due to wrong mouse acceleration settings in the guests X display. Advertise either absolute or relative coordinates to the input system and the evdev driver, depending on what dom0 provides. The xorg-input driver prefers relative coordinates even if a devices provides both. Signed-off-by:
