Add new helper functions snd_soc_component_get_kcontrol() and
snd_soc_component_get_kcontrol_locked() that returns a kcontrol
by name, but will factor in the components name_prefix, to handle
situations where multiple components are present with the same

The only existing caller of thermal_zone_get_num_trips(), which is
rcar_gen3_thermal_probe(), uses this function to put the number of
trip points into a kernel log message, but this information is also
available from the thermal sysfs interface.
For this reason, remove the thermal_zone_get_num_trips() call from
rcar_gen3_thermal_probe() and drop the former altogether.

This way uprobe_unregister() and uprobe_apply() can use "struct uprobe *"
rather than inode + offset. This simplifies the code and allows to avoid
the unnecessary find_uprobe() + put_uprobe() in these functions.
TODO: uprobe_unregister() still needs get_uprobe/put_uprobe to ensure that
this uprobe can't be freed before up_write(&uprobe->register_rwsem).

It doesn't make any sense to have 2 versions of _register(). Note that
trace_uprobe_enable(), the only user of uprobe_register(), doesn't need
to check tu->ref_ctr_offset to decide which one should be used, it could
safely pass ref_ctr_offset == 0 to uprobe_register_refctr().
Add this argument to uprobe_register(), update the callers, and kill
uprobe_register_refctr().

When tracing user functions with uprobe functionality, it's common to
install the probe (e.g., a BPF program) at the first instruction of the
function. This is often going to be `push %rbp` instruction in function
preamble, which means that within that function frame pointer hasn't
been established yet. This leads to consistently missing an actual
caller of the traced function, because perf_callchain_user() only
records current IP (capturing traced function) and then following frame
pointer chain (which would be caller's frame, containing the address of
caller's caller).
So when we have target_1 -> target_2 -> target_3 call chain and we are
tracing an entry to target_3, captured stack trace will report
target_1 -> target_3 call chain, which is wrong and confusing.
This patch proposes a x86-64-specific heuristic to detect `push %rbp`
(`push %ebp` on 32-bit architecture) instruction being traced. Given
entire kernel implementation of user space stack trace capturing works
under assumption that user space code was compiled with frame pointer
register (%rbp/%ebp) preservation, it seems pretty reasonable to use
this instruction as a strong indicator that this is the entry to the
function. In that case, return address is still pointed to by %rsp/%esp,
so we fetch it and add to stack trace before proceeding to unwind the
rest using frame pointer-based logic.
We also check for `endbr64` (for 64-bit modes) as another common pattern
for function entry, as suggested by Josh Poimboeuf. Even if we get this
wrong sometimes for uprobes attached not at the function entry, it's OK
because stack trace will still be overall meaningful, just with one
extra bogus entry. If we don't detect this, we end up with guaranteed to
be missing caller function entry in the stack trace, which is worse
overall.

This change allows events to use PERF_SAMPLE_READ with inherit
so long as PERF_SAMPLE_TID is also set. This enables sample based
profiling of a group of counters over a hierarchy of processes or
threads. This is useful, for example, for collecting per-thread
counters/metrics, event based sampling of multiple counters as a unit,
access to the enabled and running time when using multiplexing and so
on.
Prior to this, users were restricted to either collecting aggregate
statistics for a multi-threaded/-process application (e.g. with
"perf stat"), or to sample individual threads, or to profile the entire
system (which requires root or CAP_PERFMON, and may produce much more
data than is required). Theoretically a tool could poll for or otherwise
monitor thread/process creation and construct whatever events the user
is interested in using perf_event_open, for each new thread or process,
but this is racy, can lead to file-descriptor exhaustion, and ultimately
just replicates the behaviour of inherit, but in userspace.
This configuration differs from inherit without PERF_SAMPLE_READ in that
the accumulated event count, and consequently any sample (such as if
triggered by overflow of sample_period) will be on a per-thread rather
than on an aggregate basis.
The meaning of read_format::value field of both PERF_RECORD_READ and
PERF_RECORD_SAMPLE is changed such that if the sampled event uses this
new configuration then the values reported will be per-thread rather
than the global aggregate value. This is a change from the existing
semantics of read_format (where PERF_SAMPLE_READ is used without
inherit), but it is necessary to expose the per-thread counter values,
and it avoids reinventing a separate "read_format_thread" field that
otherwise replicates the same behaviour. This change should not break
existing tools, since this configuration was not previously valid and
was rejected by the kernel. Tools that opt into this new mode will need
to account for this when calculating the counter delta for a given
sample. Tools that wish to have both the per-thread and aggregate value
can perform the global aggregation themselves from the per-thread
values.
The change to read_format::value does not affect existing valid
perf_event_attr configurations, nor does it change the behaviour of
calls to "read" on an event descriptor. Both continue to report the
aggregate value for the entire thread/process hierarchy. The difference
between the results reported by "read" and PERF_RECORD_SAMPLE in this
new configuration is justified on the basis that it is not (easily)
possible for "read" to target a specific thread (the caller only has
the fd for the original parent event).

Introduce support for virtio_transport_unsent_bytes
ioctl for virtio_transport, vhost_vsock and vsock_loopback.
For all transports the unsent bytes counter is incremented
in virtio_transport_get_credit.
In virtio_transport (G2H) and in vhost-vsock (H2G) the counter
is decremented when the skbuff is consumed. In vsock_loopback the
same skbuff is passed from the transmitter to the receiver, so
the counter is decremented before queuing the skbuff to the
receiver.

We want to determine the size of the devcoredump before writing it out.
To that end, we will run the devcoredump printer with NULL data to get
the size, alloc data based on the generated offset, then run the
devcorecump again with a valid data pointer to print. This necessitates
not writing data to the data pointer on the initial pass, when it is
NULL.

Merge series from Vijendar Mukunda <Vijendar.Mukunda@amd.com>:
This patch series majorly consists of below changes.
- Rename structures, macros and codec helper names used in Intel
SoundWire generic driver to make it generic.
- Move Intel SoundWire driver common structures, macros and codec
helper functions to common placeholder so that it can be used by
other platform machine driver.
- Refactor few SoundWire common codec helper functions.
- AMD SOF based generic SoundWire machine driver for ACP 6.3 variant.
This work started a couple of months ago to avoid duplication of code
that wasn't really Intel-specific in the "sof_sdw" machine driver.
The code went through multiple iterations, was tested for multiple weeks
and a couple of build issues reported by the Intel kbuild bots were
corrected.
This is the initial version of SoundWire machine driver for AMD
platforms. Additional code refactoring will be done in the next step on
the AMD side.

workqueue_online_cpu(). When cpu stalls at the idle loop, the reschedule
IPI is pending. However the enable bit is not enabled yet so the cpu stalls
at WFI until watchdog timeout. Therefore enable the IPI before the
workqueue_online_cpu() to fix the issue.

matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the chip by modelling it as an MFD device, with two

The driver is derived from an initial implementation from NXP, available

The recent changes in IOMMU made the non-contiguous page allocations
as default, hence we can simply use the standard DMA allocation for
the S/G pages as well. In this patch, we simplify the code by trying
the standard DMA allocation at first, instead of
dma_alloc_noncontiguous().
For the case without IOMMU, we still need to manage the S/G pages
manually, so we keep the same fallback routines like before.
The fallback types (SNDRV_DMA_TYPE_DEV_SG_FALLBACK & co) are dropped /
folded into SNDRV_DMA_TYPE_DEV_SG and co now. The allocation via the
standard DMA call overrides the type accordingly, hence we don't have
to have extra fallback types any longer. OTOH, SNDRV_DMA_TYPE_DEV_SG
is no longer an alias but became its own type back again.
Note that this patch requires another prerequisite fix for memmalloc
helper to use the DMA API for WC pages on x86.

This patch modifies the skb_unref function to skip the early return
optimization when CONFIG_DEBUG_NET is enabled. The change ensures that
the reference count decrement always occurs in debug builds, allowing
for more thorough checking of SKB reference counting.
Previously, when the SKB's reference count was 1 and CONFIG_DEBUG_NET
was not set, the function would return early after a memory barrier
(smp_rmb()) without decrementing the reference count. This optimization
assumes it's safe to proceed with freeing the SKB without the overhead
of an atomic decrement from 1 to 0.
With this change:
- In non-debug builds (CONFIG_DEBUG_NET not set), behavior remains
unchanged, preserving the performance optimization.
- In debug builds (CONFIG_DEBUG_NET set), the reference count is always
decremented, even when it's 1, allowing for consistent behavior and
potentially catching subtle SKB management bugs.
This modification enhances debugging capabilities for networking code
without impacting performance in production kernels. It helps kernel
developers identify and diagnose issues related to SKB management and
reference counting in the network stack.
