commit cd9e83e2754465856097f31c7ab933ce74c473f8 upstream.
At least the Dell Vostro 5470 elantech *clickpad* reports right button
clicks when clicked in the right bottom area:
https://bugzilla.redhat.com/show_bug.cgi?id=1103528
This is different from how (elantech) clickpads normally operate, normally
no matter where the user clicks on the pad the pad always reports a left
button event, since there is only 1 hardware button beneath the path.
It looks like Dell has put 2 buttons under the pad, one under each bottom
corner, causing this.
Since this however still clearly is a real clickpad hardware-wise, we still
want to report it as such to userspace, so that things like finger movement
in the bottom area can be properly ignored as it should be on clickpads.
So deal with this weirdness by simply mapping a right click to a left click
on elantech clickpads. As an added advantage this is something which we can
simply do on all elantech clickpads, so no need to add special quirks for
this weird model.

commit 824efd37415961d38821ecbd9694e213fb2e8b32 upstream.
Commit c039450 (Input: synaptics - handle out of bounds values from the
hardware) caused any hardware reported values over 7167 to be treated as
a wrapped-around negative value. It turns out that some firmware uses
the value 8176 to indicate a finger near the edge of the touchpad whose
actual position cannot be determined. This value now gets treated as
negative, which can cause pointer jumps and broken edge scrolling on
these machines.
I only know of one touchpad which reports negative values, and this
hardware never reports any value lower than -8 (i.e. 8184). Moving the
threshold for treating a value as negative up to 8176 should work fine
then for any hardware we currently know about, and since we're dealing
with unspecified behavior it's probably the best we can do. The special
8176 value is also likely to result in sudden jumps in position, so
let's also clamp this to the maximum specified value for the axis.

commit 421e08c41fda1f0c2ff6af81a67b491389b653a5 upstream.
The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad.
However, these new Synaptics devices report bad axis ranges.
Under Windows, it is not a problem because the Windows driver uses RMI4
over SMBus to talk to the device. Under Linux, we are using the PS/2
fallback interface and it occurs the reported ranges are wrong.
Of course, it would be too easy to have only one range for the whole
series, each touchpad seems to be calibrated in a different way.
We can not use SMBus to get the actual range because I suspect the firmware
will switch into the SMBus mode and stop talking through PS/2 (this is the
case for hybrid HID over I2C / PS/2 Synaptics touchpads).
So as a temporary solution (until RMI4 land into upstream), start a new
list of quirks with the min/max manually set.

commit c15bdfd5b9831e4cab8cfc118243956e267dd30e upstream.
The current assumption in the elantech driver that hw version 3 touchpads
are never clickpads and hw version 4 touchpads are always clickpads is
wrong.
There are several bug reports for this, ie:
https://bugzilla.redhat.com/show_bug.cgi?id=1030802
http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux
I've spend a couple of hours wading through various bugzillas, launchpads
and forum posts to create a list of fw-versions and capabilities for
different laptop models to find a good method to differentiate between
clickpads and versions with separate hardware buttons.
Which shows that a device being a clickpad is reliable indicated by bit 12
being set in the fw_version. I've included the gathered list inside the
driver, so that we've this info at hand if we need to revisit this later.

commit c0394506e69b37c47d391c2a7bbea3ea236d8ec8 upstream.
The touchpad on the Acer Aspire One D250 will report out of range values
in the extreme lower portion of the touchpad. These appear as abrupt
changes in the values reported by the hardware from very low values to
very high values, which can cause unexpected vertical jumps in the
position of the mouse pointer.
What seems to be happening is that the value is wrapping to a two's
compliment negative value of higher resolution than the 13-bit value
reported by the hardware, with the high-order bits being truncated. This
patch adds handling for these values by converting them to the
appropriate negative values.
The only tricky part about this is deciding when to treat a number as
negative. It stands to reason that if out of range values can be
reported on the low end then it could also happen on the high end, so
not all out of range values should be treated as negative. The approach
taken here is to split the difference between the maximum legitimate
value for the axis and the maximum possible value that the hardware can
report, treating values greater than this number as negative and all
other values as positive. This can be tweaked later if hardware is found
that operates outside of these parameters.

commit 4ef38351d770cc421f4a0c7a849fd13207fc5741 upstream.
This patch supports the separate handling of the USB transfer buffer length
and the length of the buffer used for multi packet support. For devices
supporting multiple report or diagnostic packets, the USB transfer size is now
limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the
configured report packet size as before.
This fixes an issue where event reporting can be delayed for an arbitrary
time for multi packet devices. For instance the report size for eGalax devices
is defined to the 16 byte maximum diagnostic packet size as opposed to the 5
byte report packet size. In case the driver requests 16 byte from the USB
interrupt endpoint, the USB host controller driver needs to split up the
request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte.
When the first transfer is answered by the eGalax device with not less than
the full 8 byte requested, the host controller has got no way of knowing
whether the touch controller has got additional data queued and will issue
the second transfer. If per example a liftoff event finishes at such a
wMaxPacketSize boundary, the data will not be available to the usbtouch driver
until a further event is triggered and transfered to the host. From user
perspective the BTN_TOUCH release event in this case is stuck until the next
touch down event.

commit dfaaed08ecc01bd513248ba7999daf50ce028352 upstream.
Moust (if not all) modern software, including X, uses /dev/eventX rather than
the legacy /dev/mouseX devices. It therefore makes sense for general-purpose
(distro) kernels to use MOUSEDV=m (or even n), so let's drop the EXPERT=y
requirement.

commit bcd2623073e98f69f84720308db0b142c4da0bd6 upstream.
There is plenty of consumer hardware (e.g., mac books) that does not use AT
keyboards or PS/2 mice. It therefore makes sense for distro kernels to
build the related drivers as modules to avoid loading them on hardware that
does not need them. As such, these options should no longer be protected by
EXPERT.
Moreover, building these drivers as modules gets rid of the following ugly
error during boot:

commit ad68652412276f68ad4fe3e1ecf5ee6880876783 upstream.
Some MSI laptop BIOSes are broken - INT 15h code uses port 92h to enable A20
line but resume code assumes that KBC was used.
The laptop will not resume from S3 otherwise but powers off after a while
and then powers on again stuck with a blank screen.
Fix it by enabling A20 using KBC in i8042_platform_init for x86.

commit 4eef6cbfcc03b294d9d334368a851b35b496ce53 upstream.
The EETI touchscreen asserts its IRQ line as soon as it has data in its
internal buffers. The line is automatically deasserted once all data has
been read via I2C. Hence, the driver has to monitor the GPIO line and
cannot simply rely on the interrupt handler reception.
In the current implementation of the driver, irq_to_gpio() is used to
determine the GPIO number from the i2c_client's IRQ value.
As irq_to_gpio() is not available on all platforms, this patch changes
this and makes the driver ignore the passed in IRQ. Instead, a GPIO is
added to the platform_data struct and gpio_to_irq is used to derive the
IRQ from that GPIO. If this fails, bail out. The driver is only able to
work in environments where the touchscreen GPIO can be mapped to an
IRQ.
Without this patch, building raumfeld_defconfig results in:
drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active':
drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration]

Pull x32 support for x86-64 from Ingo Molnar:
"This tree introduces the X32 binary format and execution mode for x86:
32-bit data space binaries using 64-bit instructions and 64-bit kernel
syscalls.
This allows applications whose working set fits into a 32 bits address
space to make use of 64-bit instructions while using a 32-bit address
space with shorter pointers, more compressed data structures, etc."

Even though ams-delta-serio input driver uses gpio_to_irq() in all
relevent places to get irq number, the ams_delta_serio_exit() still
uses OMAP_GPIO_IRQ macro. Fix this.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system
Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."
Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per
Russell.

Pull "ARM: board specific updates" from Arnd Bergmann/Olof Johansson:
"These changes are all specific to one board only. We're trying to
keep the number of board files low, but generally board level updates
are ok on platforms that are working on moving towards DT based
probing, which will eventually lead to removing them.
The board-ams-delta.c board file gets a conflict between the removal
of ams_delta_config and the addition of a lot of other data. The
Kconfig file has two changes in the same line, and in exynos, the
power domain cleanup conflicts with the addition of the image sensor
device.

On multi-platform kernels, the Amiga joystick driver may be initialized
when running on Amiga only. Else it may crash later.
Fortunately this driver is almost always compiled as a module (to avoid
conflicts with the mouse driver), so it needs an explicit insmod to
trigger a crash.
