Currently we first to try to unbind the VMA (and lazily rebind on next
use) as an optimisation during restore_ggtt_mappings. Ideally, the only
objects in the GGTT upon resume are the pinned kernel objects which
can't be unbound and need to be restored. As the unbind interferes with
the plan to mark those objects as active for error capture, forgo the
optimisation.

Previous versions of `iio_compute_scan_bytes` only aligned each element
to its own length (i.e. its own natural alignment). Because multiple

case the computed scan bytes do not align with the natural alignment of
the first scan element in the set.
This commit fixes this by aligning the scan bytes to the natural

At the moment, attempting to probe a device with ST_LSM6DS3_ID
(e.g. using the st,lsm6ds3 compatible) fails with:
st_lsm6dsx_i2c 1-006b: unsupported whoami [69]
... even though 0x69 is the whoami listed for ST_LSM6DS3_ID.
This happens because st_lsm6dsx_check_whoami() also attempts
to match unspecified (zero-initialized) entries in the "id" array.
ST_LSM6DS3_ID = 0 will therefore match any entry in
st_lsm6dsx_sensor_settings (here: the first), because none of them
actually have all 12 entries listed in the "id" array.
Avoid this by additionally checking if "name" is set,
which is only set for valid entries in the "id" array.
Note: Although the problem was introduced earlier it did not surface until
commit 52f4b1f196 ("iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1")
because ST_LSM6DS3_ID was the first entry in st_lsm6dsx_sensor_settings.

This patch fixes device tree channel configuration.
ad7124 driver reads channels configuration from the device tree.
It expects to find channel specifications as child nodes.
Before this patch ad7124 driver assumed that the child nodes are parsed
by for_each_available_child_of_node in the order 0,1,2,3...
This is wrong and the real order of the children can be seen by running:
dtc -I fs /sys/firmware/devicetree/base on the machine.
For example, running this on an rpi 3B+ yields the real
children order: 4,2,0,7,5,3,1,6
Before this patch the driver assigned the channel configuration
like this:
- 0 <- 4
- 1 <- 2
- 2 <- 0
........
For example, the symptoms can be observed by connecting the 4th channel
to a 1V tension and then reading the in_voltage0-voltage19_raw sysfs
(multiplied of course by the scale) one would see that channel 0
measures 1V and channel 4 measures only noise.
Now the driver uses the reg property of each child in order to
correctly identify to which channel the parsed configuration
belongs to.

Merge tag 'clone3-tls-v5.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull thread fixes from Christian Brauner:
"This contains a series of patches to fix CLONE_SETTLS when used with
clone3().
The clone3() syscall passes the tls argument through struct clone_args
instead of a register. This means, all architectures that do not
implement copy_thread_tls() but still support CLONE_SETTLS via
copy_thread() expecting the tls to be located in a register argument
based on clone() are currently unfortunately broken. Their tls value
will be garbage.
The patch series fixes this on all architectures that currently define
__ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure
that any architecture that enables clone3() in the future is forced to
also implement copy_thread_tls().
My ultimate goal is to get rid of the copy_thread()/copy_thread_tls()
split and just have copy_thread_tls() at some point in the not too
distant future (Maybe even renaming copy_thread_tls() back to simply
copy_thread() once the old function is ripped from all arches). This
is dependent now on all arches supporting clone3().
While all relevant arches do that now there are still four missing:
ia64, m68k, sh and sparc. They have the system call reserved, but not
implemented. Once they all implement clone3() we can get rid of
ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS.
This series also includes a minor fix for the arm64 uapi headers which
caused __NR_clone3 to be missing from the exported user headers.
Unfortunately the series came in a little late especially given that
it touches a range of architectures. Due to the holidays not all arch
maintainers responded in time probably due to their backlog. Will and
Arnd have thankfully acked the arm specific changes.
Given that the changes are straightforward and rather minimal combined
with the fact the that clone3() with CLONE_SETTLS is broken I decided
to send them post rc3 nonetheless"

We've got quite a few bug reports showing the SOF driver being loaded
unintentionally recently, and the reason seems to be that users didn't
know the module option change: with the recent kernel, a new option
dsp_driver=1 has to be passed to a new module snd-intel-dspcfg
instead of snd_hda_intel.dmic_detect=0 option.
That is, actually there are two tricky things here:
- We changed the whole detection in another module and another
option semantics.
- The existing option for skipping the DSP probe was also renamed.
For avoiding the confusion and giving user more hint, this patch
reverts the renamed option dsp_driver back to dmic_detect for
snd-hda-intel module, and show the warning about the module option
change when the non-default value is passed.

The commit cited below causes devlink to emit a warning if a type was
not set on a devlink port for longer than 30 seconds to "prevent
misbehavior of drivers". This proved to be problematic when
unregistering the backing netdev. The flow is always:
devlink_port_type_clear() // schedules the warning
unregister_netdev() // blocking
devlink_port_unregister() // cancels the warning
The call to unregister_netdev() can block for long periods of time for
various reasons: RTNL lock is contended, large amounts of configuration
to unroll following dismantle of the netdev, etc. This results in
devlink emitting a warning despite the driver behaving correctly.
In emulated environments (of future hardware) which are usually very
slow, the warning can also be emitted during port creation as more than
30 seconds can pass between the time the devlink port is registered and
when its type is set.
In addition, syzbot has hit this warning [1] 1974 times since 07/11/19
without being able to produce a reproducer. Probably because
reproduction depends on the load or other bugs (e.g., RTNL not being
released).
To prevent bogus warnings, increase the timeout to 1 hour.

We observed a large(order-3) allocation in evdev_open() and it may
cause an OOM kernel panic in kzalloc(), before we getting to the

OOM killer logic as we have a vmalloc fallback.
