The existing SocketCAN implementation provides alloc_candev() to
allocate a CAN device using a single Tx and Rx queue. This can lead to
priority inversion in case the single Tx queue is already full with low
priority messages and a high priority message needs to be sent while the
bus is fully loaded with medium priority messages.
This problem can be solved by using the existing multi-queue support of
the network subsytem. The commit makes it possible to use multi-queue in
the CAN subsystem in the same way it is used in the Ethernet subsystem
by adding an alloc_candev_mqs() call and accompanying macros. With this
support a CAN device can use multi-queue qdisc (e.g. mqprio) to avoid
the aforementioned priority inversion.
The exisiting functionality of alloc_candev() is the same as before.
CAN devices need to have prioritized multiple hardware queues or are
able to abort waiting for arbitration to make sensible use of
multi-queues.

Last round of FSI updates for 4.19
This adds a few fixes for things reported since the last merge,
and the latch batch of changes pending for FSI for 4.19.
That batch is a rather mechanical conversion of the misc devices
into proper char devices.
The misc devices were ill suited, the minor space for them is
limited and we can have a lot of chips in a system creating FSI
devices.
This also allows us to better control (and fix) object lifetime
getting rid of the bad devm_kzalloc() of the structures containing
the devices etc...
Finally, we add a chardev to the core FSI that provides raw CFAM
access to FSI slaves as a replacement for the current "raw" binary
sysfs file which will be ultimately deprecated and removed.
This is needed to make rave-sp-eeprom driver work on "legacy"

The various FSI devices (sbefifo, occ, scom, more to come)
currently use misc devices.
This is problematic as the minor device space for misc is
limited and there can be a lot of them. Also it limits our
ability to move them to a dedicated /dev/fsi directory or
to be smart about device naming and numbering.
It also means we have IDAs on every single of these drivers
This creates a common fsi "device_type" for the optional
/dev/fsi grouping and a dev_t allocator for all FSI devices.
"Legacy" devices get to use a backward compatible numbering
scheme (as long as chip id <16 and there's only one copy
of a given unit type per chip).
A single major number and a single IDA are shared for all
FSI devices.
This doesn't convert the FSI device drivers to use the new
scheme yet, they will be converted individually.

In the last patch in this series, we are making lockdep register hooks
onto the irq_{disable,enable} tracepoints. These tracepoints use the
_rcuidle tracepoint variant. In this series we switch the _rcuidle
tracepoint callers to use SRCU instead of sched-RCU. Inorder to
dereference the pointer to the probe functions, we could call
srcu_dereference, however this API will call back into lockdep to check
if the lock is held *before* the lockdep probe hooks have a chance to
run and annotate the IRQ enabled/disabled state.
For this reason we need a notrace variant of srcu_dereference since
otherwise we get lockdep splats. This patch adds the needed
srcu_dereference_notrace variant.

Samsung pinctrl drivers changes for v4.19
1. Add handling of external wakeup interrupts mask inside the pin
controller driver.
Existing solution is spread between the driver and machine code. The
machine code writes the mask but its value is taken from pin
controller driver.
This moves everything into pin controller driver allowing later to
remove the cross-subsystem interaction. Also this is a necessary
step for implementing later Suspend to RAM on ARMv8 Exynos5433.
2. Bring necessary suspend/resume callbacks for Exynos542x and

3. Document hidden requirement about one external wakeup interrupts

4. Minor documentation cleanups.

Maintain the tracing on/off setting of the ring_buffer when switching
to the trace buffer snapshot.
Taking a snapshot is done by swapping the backup ring buffer
(max_tr_buffer). But since the tracing on/off setting is defined
by the ring buffer, when swapping it, the tracing on/off setting
can also be changed. This causes a strange result like below:
/sys/kernel/debug/tracing # cat tracing_on
1
/sys/kernel/debug/tracing # echo 0 > tracing_on
/sys/kernel/debug/tracing # cat tracing_on
0
/sys/kernel/debug/tracing # echo 1 > snapshot
/sys/kernel/debug/tracing # cat tracing_on
1
/sys/kernel/debug/tracing # echo 1 > snapshot
/sys/kernel/debug/tracing # cat tracing_on
0
We don't touch tracing_on, but snapshot changes tracing_on
setting each time. This is an anomaly, because user doesn't know
that each "ring_buffer" stores its own tracing-enable state and
the snapshot is done by swapping ring buffers.

The reasons why dma_free_attrs() should not be called from IRQ context
are not necessarily obvious and somewhat buried in the development
history, so let's start by documenting the warning itself to help anyone
who does happen to hit it and wonder what the deal is.
However, this check turns out to be slightly over-restrictive for the
way that per-device memory has been spliced into the general API, since
for that case we know that dma_declare_coherent_memory() has created an
appropriate CPU mapping for the entire area and nothing dynamic should
be happening. Given that the usage model for per-device memory is often
more akin to streaming DMA than 'real' coherent DMA (e.g. allocating and
freeing space to copy short-lived packets in and out), it is also
somewhat more reasonable for those operations to happen in IRQ handlers
for such devices.
Therefore, let's move the irqs_disabled() check down past the per-device
area hook, so that that gets a chance to resolve the request before we
reach definite "you're doing it wrong" territory.

And where the previous unwinder only needed BP,SP ORC also requires
IP. But we cannot spoof IP because then the sample will get displaced,
entirely negating the point of PEBS.
So cure the whole thing differently by doing the unwind early; this
does however require a means to communicate we did the unwind early.
We (ab)use an unused sample_type bit for this, which we set on events
that fill out the data->callchain before the normal
perf_prepare_sample().

The pinctrl driver defines an IRQ chip which handles external wakeup
interrupts, therefore from logical point of view, it is the owner of
external interrupt mask. The register controlling the mask belongs to
Power Management Unit address space so it has to be accessed with PMU
syscon regmap handle.
This mask should be written to hardware during system suspend. Till now
ARMv7 machine code was responsible for this which created a dependency
between pin controller driver and arch/arm/mach code.
Try to rework this dependency so the pinctrl driver will write external
wakeup interrupt mask during late suspend.
Impact on ARMv7 designs (S5Pv210 and Exynos)
============================================
This duplicates setting mask with existing machine code
arch/arm/mach-exynos/suspend.c and arch/arm/mach-s5pv210/pm.c but it is
not a problem - the wakeup mask register will be written twice. The
machine code will be cleaned up later.
The difference between implementation here and ARMv7 machine code
(arch/arm/mach-*) is the time of writing the mask:
1. The machine code is writing the mask quite late during system suspend
path, after offlining secondary CPUs and just before doing actual
suspend.
2. The implementation in pinctrl driver uses late suspend ops, therefore it
will write the mask much earlier. Hopefully late enough, after all
drivers will enable or disable their interrupt wakeups
(enable_irq_wake() etc).
Impact on ARMv8 designs (Exynos5433 and Exynos7)
================================================
The Suspend to RAM was not supported and external wakeup interrupt mask
was not written to HW. This change brings us one step closer to
supporting Suspend to RAM.
