module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Acked-by: Mauro Carvalho Chehab

This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.The microcode_core.c patch was provided by Stephen Rothwell
who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.Signed-off-by: Greg Kroah-Hartman

Several protocol initialization routines can fail after they set up
psmouse methods, such as reconnect and disconnect. This may lead to
these stale methods used with different protocol that they were
intended to be used for and may cause unpredictavle behavior and/or
crashes.Make sure we start with a clean slate before executing each and every
protocol detection and/or initialization routine.Reported-by: Paul Fox

Synaptics touchpads on several Dell laptops, particularly Vostro V13
systems, may not respond properly to PS/2 commands and queries immediately
after resuming from suspend to RAM. This leads to unresponsive touchpad
after suspend/resume cycle.Adding a 1-second delay after resetting the device allows touchpad to
finish initializing (calibrating?) and start reacting properly.Reported-by: Daniel Manrique

We have determined that the jumpiness previously seen when using
the synaptics kernel mouse driver on OLPC XO was due to not using
the synaptics X11 userspace driver - the xf86-input-evdev driver was
interpreting 'finger near pad' signals as movements. Newer versions
of xf86-input-evdev fix this issue.Additionally, the synaptics kernel driver is now usable on this
platform, but only when run in relative mode.Update the comment and refine the check to allow the synaptics driver
to run on OLPC XO in relative mode.We will continue investigating the EC issue as time becomes available.

Currently, the synaptics driver puts the device into Absolute mode.
As explained in the synaptics documentation section 3.2, in this mode,
the device sends a continuous stream of packets at the maximum rate
to the host when the user's fingers are near or on the pad or
pressing buttons, and continues streaming for 1 second afterwards.
These packets are even sent when there is no new information to report,
even when they are duplicates of the previous packet.For embedded systems this is a bit much - it results in a huge
and uninterrupted stream of interrupts at high rate.This patch adds support for Relative mode, which can be selected as
a new psmouse protocol. In this mode, the device does not send duplicate
packets and acts like a standard PS/2 mouse. However, synaptics-specific
functionality is still available, such as the ability to set the packet
rate, and rather than disabling gestures and taps at the hardware level
unconditionally, a 'synaptics_disable_gesture' sysfs attribute has
been added to allow control of this functionality.This solves a long standing OLPC issue: synaptics hardware enables
tap to click by default (even in the default relative mode), but we
have found this to be inappropriate for young children and first
time computer users. Enabling the synaptics driver disables tap-to-click,
but we have previously been unable to use this because it also enables
Absolute mode, which is too "spammy" for our desires and actually
overloads our EC with its continuous stream of packets. Now we can enable
the synaptics driver, disabling tap to click while retaining the less
noisy Relative mode.Signed-off-by: Daniel Drake

V2 hardware has many variants. This patch adddresses two issues:
- some model also has debounce packets, but with a different signature
than v3. Now we just check debounce for all v2 hardware.- due to different scanning methods the hardware uses, x and y ranges have
to be calculated differently. And for some specific versions, we can just
see them as custom-made, so set {x, y} the same values as Windows driver
does.Signed-off-by: JJ Ding
