Merge tag 'nfs-for-3.18-3' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client bugfixes from Trond Myklebust:
"Highlights include:
- stable patches to fix NFSv4.x delegation reclaim error paths
- fix a bug whereby we were advertising NFSv4.1 but using NFSv4.2
features
- fix a use-after-free problem with pNFS block layouts
- fix a memory leak in the pNFS files O_DIRECT code
- replace an intrusive and Oops-prone performance fix in the NFSv4
atomic open code with a safer one-line version and revert the two
original patches"

+Currently the Linux Elantech touchpad driver is aware of four different
+hardware versions unimaginatively called version 1,version 2, version 3
+and version 4. Version 1 is found in "older" laptops and uses 4 bytes per
+packet. Version 2 seems to be introduced with the EeePC and uses 6 bytes
+per packet, and provides additional features such as position of two fingers,
+and width of the touch. Hardware version 3 uses 6 bytes per packet (and
+for 2 fingers the concatenation of two 6 bytes packets) and allows tracking
+of up to 3 fingers. Hardware version 4 uses 6 bytes per packet, and can
+combine a status packet with multiple head or motion packets. Hardware version
+4 allows tracking up to 5 fingers.
+
+Some Hardware version 3 and version 4 also have a trackpoint which uses a
+separate packet format. It is also 6 bytes per packet.
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?

+ *
+ * So what we really want to do here is to shift data right

+ * Bytes: OPAL "data" LE "data"

+ * and rightmost in the LSB and can just then "cast" the u32 "data"

+ *
+ * However, an LE kernel can't. It doesn't need to swap because a
+ * load from data followed by a store to user are going to preserve
