The serio ports on i8042 are not completely isolated; while we provide
enough locking to ensure proper serialization when accessing control
and data registers AUX and KBD ports can still have an effect on each
other on PS/2 protocol level. The most prominent effect is that
issuing a command for the device connected to one port may cause
abort of the command currently executing by the device connected to
another port.

Since i8042 nor serio subsystem are not aware of the details of the
PS/2 protocol (length of the commands and their replies and so on) the
locking should be done on libps2 level by adding special handling when
we see that we are dealing with serio port on i8042.

Ever since we switched from having a polling timer to registering IRQ
handlers for both keyboard and AUX ports at the driver registration
time, on certain boxes probing for a mouse results in keyboard
stopping working. The only real difference between old and new way is
that before we disabled ports after unsuccessful probe whereas now we
leave them as is. Try to emulate the old behavior by disabling and
immediately re-enabling AUX and KBD ports when corresponding serio
port is being closed.

It seems that many laptops do not fully implement AUX LOOP command in
their keyboard controllers, causing issues with touchpad detection.
We know however that almost every laptop/portable uses a PS/2 pointing
device and, even if user disables it in favor of an external mouse,
the system will not use IRQ 12 for anything else. Therefore we may
bypass AUX IRQ delivery test when running on a laptop and assume that
it is routed properly.

Just to be safe we require the box to have good PNP data in order to
bypass the test.

There are more and more laptop requiring use of force_release quirk
for their multimedia and other specialized keys. Adding their DMI data
to the kernel is not sustainable; instead we will rely on help from
userspace (HAL) to do that for us.

This patch creates a new 'force_release' sysfs attribute (that belongs
to serio device to which keyboard is attached) which can be used to set
up force_release keymap. For example, Dell laptop owners might do:

echo 133-139,143,147 > /sys/devices/platform/i8042/serio0/force_release
