Now that we query all the parameters, adding support for new hardware
is easy. This commit adds support for the touchpad found on the
HP x2 10-n000nd touchpad 2-in-1.

hardcoding it. This makes adding support for other USB ids a lot easier.

Elan has given me a (GPL-ed) Android driver for their non HID-mt touchpads
to help improve the upstream support.
Acoording to Elan what we are currently reporting as tool-width
really is a per-touch pressure. This always has a maximum of 255, so there
is no need to make the max configurable.

uref->field_index, uref->usage_index, finfo.field_index and cinfo.index can be
indirectly controlled by user-space, hence leading to a potential exploitation
of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/hid/usbhid/hiddev.c:473 hiddev_ioctl_usage() warn: potential spectre issue 'report->field' (local cap)
drivers/hid/usbhid/hiddev.c:477 hiddev_ioctl_usage() warn: potential spectre issue 'field->usage' (local cap)
drivers/hid/usbhid/hiddev.c:757 hiddev_ioctl() warn: potential spectre issue 'report->field' (local cap)
drivers/hid/usbhid/hiddev.c:801 hiddev_ioctl() warn: potential spectre issue 'hid->collection' (local cap)
Fix this by sanitizing such structure fields before using them to index
report->field, field->usage and hid->collection
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

Commit ac75a041048b ("HID: i2c-hid: fix size check and type usage") started
writing messages when the ret_size is <= 2 from i2c_master_recv. However, my
device i2c-DLL07D1 returns 2 for a short period of time (~0.5s) after I stop
moving the pointing stick or touchpad. It varies, but you get ~50 messages
each time which spams the log hard.
[ 95.925055] i2c_hid i2c-DLL07D1:01: i2c_hid_get_input: incomplete report (83/2)

[ 1781.266353] i2c_hid i2c-ALP0017:00: i2c_hid_get_input: incomplete report (30/2)
Only print the message when ret_size is totally invalid and less than 2 to cut
down on the log spam.

The displaylink hardware has such a peculiarity that it doesn't render a
command until next command is received. This produces occasional
corruption, such as when setting 22x11 font on the console, only the first
line of the cursor will be blinking if the cursor is located at some
specific columns.
When we end up with a repeating pixel, the driver has a bug that it leaves
one uninitialized byte after the command (and this byte is enough to flush
the command and render it - thus it fixes the screen corruption), however
whe we end up with a non-repeating pixel, there is no byte appended and
this results in temporary screen corruption.
This patch fixes the screen corruption by always appending a byte 0xAF at
the end of URB. It also removes the uninitialized byte.

Current implementation does not guarantee packed pixel modes working

Write proper values to registers in packed_pixel mode, based on how it

A hooking API was implemented for 4.17 in fa93854f7a7ed63d followed
by hooks for Thinkpad laptops in 2801b9683f740012. The Thinkpad
drivers did not support the Thinkpad 13 and the hooking API crashes
on unsupported batteries by altering a list of hooks during unsafe
iteration. Thus, Thinkpad 13 laptops could no longer boot.
Additionally, a lock was kept in place and debugging information was
printed out of order.

The buffer object backing the user fence is reserved using the non-user
fence, i.e., as soon as the non-user fence is signaled, the user fence
buffer object can be moved or even destroyed.
Therefore, emit the user fence first.
Both fences have the same cache invalidation behavior, so this should

There are no legacy behavior in drivers to consider while attaching a
device to genpd - for the multiple PM domain case.
For that reason, let's instead require the driver to runtime resume the
device, via calling pm_runtime_get_sync() for example, when it needs to
power on the corresponding PM domain.
This allows us to improve the situation during attach. Instead of always
power on the PM domain, which may be unnecessary, let's leave it in its
current state. Additionally, to avoid the PM domain to stay powered on,
let's schedule a power off work.

This change adds LOOP_SET_BLOCK_SIZE as one of the supported ioctls
in lo_compat_ioctl. It only takes an unsigned long argument, and
in practice a 32-bit value works fine.

If the whole object is already pinned by HW for use as scanout, we will
fail to move it to the mappable region and so must resort to using a
partial VMA covering the whole object.

The touch sensors on the 2nd-gen Intuos tablets don't use a 4096x4096
sensor like other similar tablets (3rd-gen Bamboo, Intuos5, etc.).
The incorrect maximum XY values don't normally affect userspace since
touch input from these devices is typically relative rather than
absolute. It does, however, cause problems when absolute distances
need to be measured, e.g. for gesture recognition. Since the resolution
of the touch sensor on these devices is 10 units / mm (versus 100 for
the pen sensor), the proper maximum values can be calculated by simply
dividing by 10.

Currently, we use the ACPI processor ID only for the leaf/processor nodes
as the specification states it must match the value of the ACPI processor
ID field in the processor’s entry in the MADT.
However, if a PPTT structure represents a processors group, it
matches a processor container UID in the namespace and the
ACPI_PPTT_ACPI_PROCESSOR_ID_VALID flag indicates whether the
ACPI processor ID is valid.
Let's use UID whenever ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set to be
consistent instead of using table offset as it's currently done for
non-leaf nodes.
