platform to provide its own sysrq sequence at compile time. After over two
years, nobody has started using it in an upstream kernel, and the platforms
that were interested in it have moved on to devicetree, which can be used
to configure the sequence without requiring kernel changes. The method is
also incompatible with the way that most architectures build support for
multiple platforms into a single kernel.
Now the code is producing warnings when built with gcc-5.1:

let's just remove the code instead. We still have the option to pass the
sequence either in DT, using the kernel command line, or using the

much better data for the first touch and for the single touch
pointer-emulation events.
This approach is similar to the one in alps_process_bitmap_dolphin, that
function takes the single accurate touch info, calculates the distance to
the center of the bounding box, and then puts the 2nd touch mirrored to
the center. The downside of that approach is that if both touches move
slowly in the same direction, the bounding box will stay the same for a
while (as it is low res) and the second touch will thus been seen moving
in the opposite direction until the bounding box actually changes, and
then the second touch snaps to its new position resulting in a saw tooth
pattern in the coordinates for the second touch, hence this new approach.
This commit fixes 2 finger scrolling being choppy / jumpy on these
touchpads.

Pinnacle / Rushmore packets contain either position info, or bitmap info,
never both. So far we've in essence been storing garbage in the position /
bitmap fields of the fields struct when decoding a bitmap / pos packet.
We've been relying on the following sequence to get away with this:
1) Decode bitmap packet
2) Process bitmap packet
3) Decode position packet
4) Use position / button info
This patch allows us to change this sequence, which will allow using the

Input: smtpe-ts - wait 50mS until polling for pen-up
Wait a little bit longer, 50mS instead of 20mS, until the driver starts
polling for pen-up. The problematic behavior before this patch is applied
is as follows. The behavior was observed on the STMPE610QTR controller.
Upon a physical pen-down event, the touchscreen reports one set of x-y-p
coordinates and a pen-down event. After that, the pen-up polling is
triggered and since the controller is not ready yet, the polling mistakenly
detects a pen-up event while the physical state is still such that the pen
is down on the touch surface.
The pen-up handling flushes the controller FIFO, so after that, all the
samples in the controller are discarded. The controller becomes ready
shortly after this bogus pen-up handling and does generate again a pen-down
interrupt. This time, the controller contains x-y-p samples which all read
as zero. Since pressure value is zero, this set of samples is effectively
ignored by userland.
In the end, the driver just bounces between pen-down and bogus pen-up
handling, generating no useful results. Fix this by giving the controller a
bit more time before polling it for pen-up.

ConnectX-2 cards startup to debug") did the deprecation only for port 1
of the card. Need to deprecate for port 2 as well.

net: dsa: fix filling routing table from OF description
According to description in 'include/net/dsa.h', in cascade switches
configurations where there are more than one interconnected devices,
'rtable' array in 'dsa_chip_data' structure is used to indicate which
port on this switch should be used to send packets to that are destined
for corresponding switch.
However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
of the _target_ switch, but not current one.
This commit removes redundant devicetree parsing and adds needed port
number as a function argument. So dsa_of_setup_routing_table() now just
looks for target switch number by parsing parent of 'link' device node.
To remove possible misunderstandings with the way of determining target
switch number, a corresponding comment was added to the source code and
to the DSA device tree bindings documentation file.
This was tested on a custom board with two Marvell 88E6095 switches with
following corresponding routing tables: { -1, 10 } and { 8, -1 }.

The logic is part of the input device initialization routine but it can be

ipv6: protect skb->sk accesses from recursive dereference inside the stack
We should not consult skb->sk for output decisions in xmit recursion
levels > 0 in the stack. Otherwise local socket settings could influence
the result of e.g. tunnel encapsulation process.
ipv6 does not conform with this in three places:
1) ip6_fragment: we do consult ipv6_npinfo for frag_size
2) sk_mc_loop in ipv6 uses skb->sk and checks if we should
loop the packet back to the local socket
3) ip6_skb_dst_mtu could query the settings from the user socket and
force a wrong MTU
Furthermore:
In sk_mc_loop we could potentially land in WARN_ON(1) if we use a
PF_PACKET socket ontop of an IPv6-backed vxlan device.
Reuse xmit_recursion as we are currently only interested in protecting
tunnel devices.

Input: synaptics - allocate 3 slots to keep stability in image sensors
When slowly dropping 1, 2 and then 3 fingers on an image sensor touchpad,
we can see that the first finger gets reassigned a new slot while it did
not move. This is due to the kernel tracking algorithm which can not assign
correctly the 3 touches, being out of slots.
Declaring that we support 3 slots allows to actually forward:
slot 0 -> down, slot 1 -> up, slot 2 -> down
