The drivers sets IRQF_ONESHOT and passes only a primary handler. The IRQ
is masked while the primary is handler is invoked independently of
IRQF_ONESHOT.
With IRQF_ONESHOT the core code will not force-thread the interrupt and
this is probably not intended. I *assume* that the original author copied
the IRQ registration from another driver which passed a primary and
secondary handler and removed the secondary handler but keeping the
ONESHOT flag.
Remove IRQF_ONESHOT.

The LSM9DS1's accelerometer / gyroscope unit and it's magnetometer (separately
supported in iio/magnetometer/st_magn*) are located on a separate i2c addresses
on the bus.
For the datasheet, see https://www.st.com/resource/en/datasheet/lsm9ds1.pdf
Treat it just like the LSM6* devices and, despite it's name, hook it up
to the st_lsm6dsx driver, using it's basic functionality.
accelerometer and gyroscope are not independently clocked. It runs at the gyro
frequencies if both are enabled, see chapter 7.12 of the datasheet.
We could have handled this as a single IIO device but we have split
it up to be more consistent with the other more flexible devices.
Despite supporting and testing the LSM9DS1, we call the gyro channels
iio_chan_spec struct "st_lsm6ds0_gyro_channels" because the register
description is equal. This suggests that supporting LSM6DS0 should be
trivial to do.

We can reduce the critical section in vkms_vblank_simulate under
output->lock quite a lot:
- hrtimer_forward_now just needs to be ordered correctly wrt
drm_crtc_handle_vblank. We already access the hrtimer timestamp
without locks. While auditing that I noticed that we don't correctly
annotate the read there, so sprinkle a READ_ONCE to make sure the
compiler doesn't do anything foolish.
- drm_crtc_handle_vblank must stay under the lock to avoid races with
drm_crtc_arm_vblank_event.
- The access to vkms_ouptut->crc_state also must stay under the lock.
- next problem is making sure the output->state structure doesn't get
freed too early. First we rely on a given hrtimer being serialized:
If we call drm_crtc_handle_vblank, then we are guaranteed that the
previous call to vkms_vblank_simulate has completed. The other side
of the coin is that the atomic updates waits for the vblank to
happen before it releases the old state. Both taken together means
that by the time the atomic update releases the old state, the
hrtimer won't access it anymore (it might be accessing the new state
at the same time, but that's ok).
- state is invariant, except the few fields separate protected by
state->crc_lock. So no need to hold the lock for that.
- finally the queue_work. We need to make sure there's no races with
the flush_work, i.e. when we call flush_work we need to guarantee
that the hrtimer can't requeue the work again. This is guaranteed by
the same vblank/hrtimer ordering guarantees like the reasoning above
why state won't be freed too early: flush_work on the old state is
called after wait_for_flip_done in the atomic commit code.
Therefore we can also move everything after the output->crc_state out
of the critical section.

Noticed while reviewing code. I'm not sure whether this might or might
not explain some of the missed vblank hilarity we've been seeing on
various drivers (but those got tracked down to driver issues, at least
mostly). I think those all go through the vblank completion event,
which has unconditional barriers - it always takes the spinlock.
Therefore no cc stable.
v2:
- Barrriers are hard, put them in in the right order (Chris).
- Improve the comments a bit.
v3:
Ville noticed that on 32bit we might be breaking up the load/stores,
now that the vblank counter has been switched over to be 64 bit. Fix
that up by switching to atomic64_t. This this happens so rarely in
practice I figured no need to cc: stable ...

Turns out the commit 3a0681c744 ("mmc: core: do not retry CMD6 in
__mmc_switch()") breaks initialization of a Toshiba THGBMNG5 eMMC card,
when using the meson-gx-mmc.c driver on a custom board based on Amlogic
A113D.
The CMD6 that switches the card into HS200 mode is then one that fails and
according to the below printed messages from the log:
[ 1.648951] mmc0: mmc_select_hs200 failed, error -84
[ 1.648988] mmc0: error -84 whilst initialising MMC card
After some analyze, it turns out that adding a delay of ~5ms inside
mmc_select_bus_width() but after mmc_compare_ext_csds() has been executed,
also fixes the problem. Adding yet some more debug code, trying to figure
out if potentially the card could be in a busy state, both by using CMD13
and ->card_busy() ops concluded that this was not the case.
Therefore, let's simply revert the commit that dropped support for retrying
of CMD6, as this also fixes the problem.

Add a new hid driver for the Creative SB0540 IR receiver. This receiver
is usually coupled with an RM-1500 or an RM-1800 remote control.
The scrollwheels on the RM-1800 remote are not bound, as they are
labelled for specific audio controls that don't usually exist on most
systems. They can be remapped using standard Linux keyboard
remapping tools.

The PixArt OEM mice are known for disconnecting every minute in

The race was when a thread using closure_sync() notices cl->s->done == 1
before the thread calling closure_put() calls wake_up_process(). Then,
it's possible for that thread to return and exit just before
wake_up_process() is called - so we're trying to wake up a process that
no longer exists.
rcu_read_lock() is sufficient to protect against this, as there's an rcu
barrier somewhere in the process teardown path.
