After commit 684bec1092b6 ("Input: i8042 - enable keyboard wakeups by default when s2idle is used"), kdb is enabled to wakeup laptops. Kbd fails to wakeup when touchpad/trackpoint is used on ThinkPad. The touchpad is not set to wakeup, and it shares buffer with kbd. Send disable command to PS/2 mouse when s2idle, make it clean for kdb to wakeup. Enable PS/2 mouse when wakeup enabled.
