list_first_or_null() should test whether the list is empty and return
pointer to the first entry if not in a RCU safe manner. It's broken
in several ways.
* It compares __kernel @__ptr with __rcu @__next triggering the
following sparse warning.
net/core/dev.c:4331:17: error: incompatible types in comparison expression (different address spaces)
* It doesn't perform rcu_dereference*() and computes the entry address
using container_of() directly from the __rcu pointer which is
inconsitent with other rculist interface. As a result, all three
in-kernel users - net/core/dev.c, macvlan, cgroup - are buggy. They
dereference the pointer w/o going through read barrier.
* While ->next dereference passes through list_next_rcu(), the
compiler is still free to fetch ->next more than once and thus
nullify the "__ptr != __next" condition check.
Fix it by making list_first_or_null_rcu() dereference ->next directly
using ACCESS_ONCE() and then use list_entry_rcu() on it like other
rculist accessors.
v2: Paul pointed out that the compiler may fetch the pointer more than
once nullifying the condition check. ACCESS_ONCE() added on
->next dereference.
v3: Restored () around macro param which was accidentally removed.
Spotted by Paul.

The VSP1 is a video processing engine that includes a blender, scalers,
filters and statistics computation. Configurable data path routing logic
allows ordering the internal blocks in a flexible way.
Due to the configurable nature of the pipeline the driver implements the
media controller API and doesn't use the V4L2 mem-to-mem framework, even
though the device usually operates in memory to memory mode.
Only the read pixel formatters, up/down scalers, write pixel formatters

Number 0x41, and 0x42 are special memory controller settings

enable memory power down function and special SDRAM clock
delay for synchronize SDRAM output and clock signal.

In the previous QUERY_PAGES command version we used one command to get the

op_mod field to specify whether the query is for the required amount of boot,
init or post init pages. In addition the output field size for the required
amount of pages increased from 16 to 32 bits.
In MANAGE_PAGES command the input_num_entries and output_num_entries fields
sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10.
In the pages request event the num_pages field also changed to 32 bits.
In the HCA-capabilities-layout the size and location of max_qp_mcg field has
been changed to support 24 bits.

Sometimes pci_reset_function() is not sufficient. We have cases where
devices do not support any kind of reset, but there might be multiple
functions on the bus preventing pci_reset_function() from doing a
secondary bus reset. We also have cases where a device will advertise
that it supports a PM reset, but really does nothing on D3hot->D0
(graphics cards are notorious for this). These devices often also
have more than one function, so even blacklisting PM reset for them
wouldn't allow a secondary bus reset through pci_reset_function().
If a driver supports multiple devices it should have the ability to
induce a bus reset when it needs to. This patch provides that ability
through pci_reset_slot() and pci_reset_bus(). It's the caller's
responsibility when using these interfaces to understand that all of
the devices in or below the slot (or on or below the bus) will be
reset and therefore should be under control of the caller. PCI state
of all the affected devices is saved and restored around these resets,
but internal state of all of the affected devices is reset (which
should be the intention).

In order to use static keys with vtime APIs, we'll need to
add static keys headers to vtime.h
hardirq.h then becomes a problem because it needs vtime.h
for irqtime accounting in irq_enter/irq_exit, but it's
often included just to get the irq mask definitions in the
task preempt_count field and the APIs that come along:
in_interrupt(), in_hardirq(), etc...
Some very low level arch headers sometimes need these masks
and APIs such as arch/m68k/include/asm/irqflags.h for example.
But they don't want to include hardirq.h if vtime.h, jump_label.h
and even workqueue.h come along. Including such bloated high
level header from arch headers can quickly result in circular
headers dependency that crash the build.
So let's split hardirq.h in two parts:
* preempt_mask.h that gathers all the preempt_count definitions
and the APIs associated. This one is considered low level and can
be safely included anywhere.
* hardirq.h that includes the previous one. It defines the irq
entry/exit APIs.
To avoid future circular headers dependencies, the preempt_mask.h
inclusion can replace hardirq.h on files that don't implement irq
low level handlers but just need the atomic/context check APIs.

We plan to use the context tracking static key on inline
vtime APIs. For this we need to include the context tracking
headers from those of vtime.
However vtime headers need to stay low level because they are
included in hardirq.h that mostly contains standalone
definitions. But context_tracking.h includes sched.h for
a few task_struct references, therefore it wouldn't be sensible
to include it from vtime.h
To solve this, lets split the context tracking headers and move
out the pure state definitions that only require a few low level
headers. We can safely include that small part in vtime.h later.

Optimize user and exception entry/exit APIs with static
keys. This minimize the overhead for those who enable
CONFIG_NO_HZ_FULL without always using it. Having no range
passed to nohz_full= should result in the probes to be nopped
(at least we hope so...).
If this proves not be enough in the long term, we'll need
to bring an exception slow path by re-routing the exception
handlers.
