Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Conflicts:
	drivers/net/ieee802154/fakehard.c

A bug fix went into 'net' for ieee802154/fakehard.c, which is removed
in 'net-next'.

Add build fix into the merge from Stephen Rothwell in openvswitch, the
logging macros take a new initial 'log' argument, a new call was added
in 'net' so when we merge that in here we have to explicitly add the
new 'log' arg to it else the build fails.

+4 allows tracking up to 5 fingers.
+
+Some Hardware version 3 and version 4 also have a trackpoint which uses a

 The driver tries to support both hardware versions and should be compatible
 with the Xorg Synaptics touchpad driver and its graphical configuration
 utilities.
 
+Note that a mouse button is also associated with either the touchpad or the
+trackpoint when a trackpoint is available.  Disabling the Touchpad in xorg
+(TouchPadOff=0) will also disable the buttons associated with the touchpad.

 Additionally the operation of the touchpad can be altered by adjusting the
 contents of some of its internal registers. These registers are represented
 by the driver as sysfs entries under /sys/bus/serio/drivers/psmouse/serio?
