NT waits can optionally be made "alertable". This is a special channel for
thread wakeup that is mildly similar to SIGIO. A thread has an internal single
bit of "alerted" state, and if a thread is alerted while an alertable wait, the
wait will return a special value, consume the "alerted" state, and will not
consume any of its objects.
Alerts are implemented using events; the user-space NT emulator is expected to
create an internal ntsync event for each thread and pass that event to wait
functions.

This wakes up any waiters as if the event had been set, but does not set the

This correspond to the NT syscall NtCreateEvent().
An NT event holds a single bit of state denoting whether it is signaled or
unsignaled.
There are two types of events: manual-reset and automatic-reset. When an
automatic-reset event is acquired via a wait function, its state is reset to
unsignaled. Manual-reset events are not affected by wait functions.
Whether the event is manual-reset, and its initial state, are specified at
creation time.

This does not correspond to any NT syscall. Rather, when a thread dies, it
should be called by the NT emulator for each mutex, with the TID of the dying
thread.
NT mutexes are robust (in the pthread sense). When an NT thread dies, any
mutexes it owned are immediately released. Acquisition of those mutexes by other
threads will return a special value indicating that the mutex was abandoned,
like EOWNERDEAD returned from pthread_mutex_lock(), and EOWNERDEAD is indeed
used here for that purpose.

This is similar to NTSYNC_IOC_WAIT_ANY, but waits until all of the objects are
simultaneously signaled, and then acquires all of them as a single atomic
operation.
Because acquisition of multiple objects is atomic, some complex locking is
required. We cannot simply spin-lock multiple objects simultaneously, as that
may disable preëmption for a problematically long time.
Instead, modifying any object which may be involved in a wait-all operation takes
a device-wide sleeping mutex, "wait_all_lock", instead of the normal object
spinlock.
Because wait-for-all is a rare operation, in order to optimize wait-for-any,
this lock is only taken when necessary. "all_hint" is used to mark objects which
are involved in a wait-for-all operation, and if an object is not, only its
spinlock is taken.
The locking scheme used here was written by Peter Zijlstra.

This corresponds to part of the functionality of the NT syscall
NtWaitForMultipleObjects(). Specifically, it implements the behaviour where
the third argument (wait_any) is TRUE, and it does not handle alertable waits.
Those features have been split out into separate patches to ease review.
This patch therefore implements the wait/wake infrastructure which comprises the
core of ntsync's functionality.
NTSYNC_IOC_WAIT_ANY is a vectored wait function similar to poll(). Unlike
poll(), it "consumes" objects when they are signaled. For semaphores, this means
decreasing one from the internal counter. At most one object can be consumed by
this function.
This wait/wake model is fundamentally different from that used anywhere else in
the kernel, and for that reason ntsync does not use any existing infrastructure,
such as futexes, kernel mutexes or semaphores, or wait_event().
Up to 64 objects can be waited on at once. As soon as one is signaled, the
object with the lowest index is consumed, and that index is returned via the
"index" field.
A timeout is supported. The timeout is passed as a u64 nanosecond value, which
represents absolute time measured against either the MONOTONIC or REALTIME clock
(controlled by the flags argument). If U64_MAX is passed, the ioctl waits
indefinitely.
This ioctl validates that all objects belong to the relevant device. This is not
necessary for any technical reason related to NTSYNC_IOC_WAIT_ANY, but will be
necessary for NTSYNC_IOC_WAIT_ALL introduced in the following patch.
Some padding fields are added for alignment and for fields which will be added
in future patches (split out to ease review).

The only reason for the ssd130x-spi driver to have an spi_device_id table
is that the SPI core always reports an "spi:" MODALIAS, even when the SPI
device has been registered via a Device Tree Blob.
Without spi_device_id table information in the module's metadata, module
autoloading would not work because there won't be an alias that matches
the MODALIAS reported by the SPI core.
This spi_device_id table is not needed for device matching though, since
the of_device_id table is always used in this case. For this reason, the
struct spi_driver .id_table member is currently not set in the SPI driver.
Because the spi_device_id table is always required for module autoloading,
the SPI core checks during driver registration that both an of_device_id
table and a spi_device_id table are present and that they contain the same
entries for all the SPI devices.
Not setting the .id_table member in the driver then confuses the core and
leads to the following warning when the ssd130x-spi driver is registered:
[ 41.091198] SPI driver ssd130x-spi has no spi_device_id for sinowealth,sh1106
[ 41.098614] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1305

[ 41.120247] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1309
[ 41.127449] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1322

[ 41.149021] SPI driver ssd130x-spi has no spi_device_id for solomon,ssd1331
To prevent the warning, set the .id_table even though it's not necessary.
Since the check is done even for built-in drivers, drop the condition to
only define the ID table when the driver is built as a module. Finally,
rename the variable to use the "_spi_id" convention used for ID tables.
