On resume from suspend there is a possibility for multi-byte scancodes to be handled incorrectly. atkbd_reconnect disables the processing of scancodes in software by calling atkbd_disable, but the keyboard may still be active because no disconnect command was sent. Later, software handling is re-enabled. If a multi-byte scancode sent from the keyboard straddles the re-enable, only the latter byte(s) will be handled. In practice, this leads to cases where multi-byte break codes (ex. "e0 4d" - break code for right-arrow) are misread as make codes ("4d" - make code for numeric 6), leading to one or more unwanted, untyped characters being interpreted. The solution implemented here involves sending command f5 (reset disable) to the keyboard prior to disabling software handling of codes. Later, the command to re-enable the keyboard is sent only after we are prepared to handle scancodes.

This patch adds keyreset functionality to the sysrq driver. It allows certain button/key combinations to be used in order to trigger emergency reboots. Redefining the '__weak platform_sysrq_reset_seq' variable is required to trigger the feature. Alternatively keys can be passed to the driver via a module parameter. This functionality comes from the keyreset driver submitted by Arve Hjønnevåg in the Android kernel.

Henrik added new MT routines in release 3.7. This patch is to prepare for the use of new MT routines. In the newly added wacom_abs_set_axis() function, the first if-statement assigns ABS_X/Y for number of contacts less or equal to 2. So, it is single and 2 finger touch devices. Two finger touch devices are processed here since they will not use the updated input_mt_init_slots(), which does not offer benefit to those devices. input_mt_init_slots() will take care of ABS_X/Y assignment when flags are not zero. All touch devices with more than two contacts will use input_mt_init_slots() with non-zero flags. The second if-statement is for all MT devices, which include two finger touch devices.
