Options

Remove uninformative coments in input.c. 

Silence hotplug printk()s in input.c
More careful probe and init in atkbd.c and psmouse.c
to avoid triggering bugs in certain keyboards.
Accept old AT (non PS/2) keyboards with limited command set.
Accept Logitech mice which can only do IMPS/2 and not PS2++.
Use a buffer in i8042.c to avoid spinlock deadlocks when
serio_write is called from within serio_interrupt.
Only ask keyboard to resent if the keyboard is there (ie no timeout).
Linus, this should fix both your keyboard and your mouse!
