NFSD initializes an encode xdr_stream only after the RPC layer has
already inserted the RPC Reply header. Thus it behaves differently
than xdr_init_encode does, which assumes the passed-in xdr_buf is
entirely devoid of content.
nfs4proc.c has this server-side stream initialization helper, but
it is visible only to the NFSv4 code. Move this helper to a place
that can be accessed by NFSv2 and NFSv3 server XDR functions.

Building with W=1 shows a few warnings for an empty macro:

Change this to an inline function to make it more robust and avoid

Add helper sof_dai_ssp_mclk to get the topology configured MCLK from a
pcm_runtime, return 0 if it is not available, and error if the dai type
is not SSP at the moment.
Export the helper for external use, e.g. from machine drivers.

Currently quirks are only allowed for Slave devices. This patch
describes the need for two quirks at the Master level.
a) bus clash
The SoundWire specification allows a Slave device to report a bus clash
with the in-band interrupt mechanism when it detects a conflict while
driving a bitSlot it owns. This can be a symptom of an electrical conflict
or a programming error, and it's vital to detect reliably.
Unfortunately, on some platforms, bus clashes are randomly reported by
Slave devices after a bus reset, with an interrupt status set even before
the bus clash interrupt is enabled. These initial spurious interrupts are
not relevant and should optionally be filtered out, while leaving the
interrupt mechanism enabled to detect 'true' issues.
This patch suggests the addition of a Master level quirk to discard such
interrupts. The quirk should in theory have been added at the Slave level,
but since the problem was detected with different generations of Slave
devices it's hard to point to a specific IP. The problem might also be
board-dependent and hence dealing with a Master quirk is simpler.
b) parity
Additional tests on a new platform with the Maxim 98373 amplifier
showed a rare case where the parity interrupt is also thrown on
startup, at the same time as bus clashes. This issue only seems to
happen infrequently and was only observed during suspend-resume stress
tests while audio is streaming. We could make the problem go away by
adding a Slave-level quirk, but there is no evidence that the issue is
actually a Slave problem: the parity is provided by the Master, which
could also set an invalid parity in corner cases.

Platform firmware may have incorrect _ADR values causing the driver
probes to fail. Add the override_ops, which when configured will allow
for quirks based on DMI etc to override the addr values.

pwmchip_add() only calls pwmchip_add_with_polarity() and nothing else. All
other users of pwmchip_add_with_polarity() are gone. So drop
pwmchip_add_with_polarity() and move the code instead to pwmchip_add().
The initial assignment to pwm->state.polarity is dropped. In every correct
usage of the PWM API this value is overwritten later anyhow.

The plane size needs to be PAGE_ALIGNED, so it is not possible to have
sizes bigger than MAX_INT - PAGE_SIZE.
We already check for overflows when that happen:
if (size < vb->planes[plane].length)
goto free;
But it is good to explicitly state our max allowed value, in order to
align with the driver expectations.

According to Rec. ITU-T T.872 (06/2012) 6.5.3
APP14 segment is for color encoding, it contains a transform flag, which
may have values of 0, 1 and 2 and are interpreted as follows:
0 - CMYK for images that are encoded with four components
- RGB for images that are encoded with three components
1 - An image encoded with three components using YCbCr colour encoding.
2 - An image encoded with four components using YCCK colour encoding.
This is used in imx-jpeg decoder, to distinguish between
YUV444 and RGB24.

YUV 4:4:4 format, with 8 bits for each component, 24 bits
per sample.
This format is used by the i.MX 8QuadMax and i.MX 8DualXPlus/8QuadXPlus

Until now, the VP8 V4L2 API was not exported as a public API,
and only defined in a private media header (media/vp8-ctrls.h).
The reason for this was a concern about the API not complete
and ready to support VP8 decoding hardware accelerators.
After reviewing the VP8 specification in detail, and now
that the API is able to support Cedrus and Hantro G1,
we can consider this ready.

A sequence counter write section must be serialized or its internal
state can get corrupted. A plain seqcount_t does not contain the
information of which lock must be held to guaranteee write side
serialization.
For xfrm_state_hash_generation, use seqcount_spinlock_t instead of plain
seqcount_t. This allows to associate the spinlock used for write
serialization with the sequence counter. It thus enables lockdep to
verify that the write serialization lock is indeed held before entering
the sequence counter write section.
If lockdep is disabled, this lock association is compiled out and has
neither storage size nor runtime overhead.

A sequence counter write section must be serialized or its internal
state can get corrupted. The "xfrm_state_hash_generation" seqcount is
global, but its write serialization lock (net->xfrm.xfrm_state_lock) is
instantiated per network namespace. The write protection is thus
insufficient.
To provide full protection, localize the sequence counter per network
namespace instead. This should be safe as both the seqcount read and
write sections access data exclusively within the network namespace. It
also lays the foundation for transforming "xfrm_state_hash_generation"
data type from seqcount_t to seqcount_LOCKNAME_t in further commits.

The Frequency Invariance Engine (FIE) is providing a frequency scaling
correction factor that helps achieve more accurate load-tracking.
Normally, this scaling factor can be obtained directly with the help of
the cpufreq drivers as they know the exact frequency the hardware is
running at. But that isn't the case for CPPC cpufreq driver.
Another way of obtaining that is using the arch specific counter
support, which is already present in kernel, but that hardware is
optional for platforms.
This patch updates the CPPC driver to register itself with the topology
core to provide its own implementation (cppc_scale_freq_tick()) of
topology_scale_freq_tick() which gets called by the scheduler on every
tick. Note that the arch specific counters have higher priority than
CPPC counters, if available, though the CPPC driver doesn't need to have
any special handling for that.
On an invocation of cppc_scale_freq_tick(), we schedule an irq work
(since we reach here from hard-irq context), which then schedules a
normal work item and cppc_scale_freq_workfn() updates the per_cpu
arch_freq_scale variable based on the counter updates since the last
tick.
To allow platforms to disable this CPPC counter-based frequency
invariance support, this is all done under CONFIG_ACPI_CPPC_CPUFREQ_FIE,
which is enabled by default.
This also exports sched_setattr_nocheck() as the CPPC driver can be
built as a module.

unregister_netdevice: waiting for sit0 to become free. Usage count = -1
