Currently, the same checks for SOCK_PASSCRED and SOCK_PASSPIDFD
are scattered across many places.
Let's centralise the bit tests to make the following changes cleaner.

The ARL requires that the GMA and NPU devices both be in D3Hot in order
for PC10 and S0iX to be achieved in S2idle. The original ARL-H/U addition
to the intel_pmc_core driver attempted to do this by switching them to D3
in the init and resume calls of the intel_pmc_core driver.
The problem is the ARL-H/U have a different NPU device and thus are not
being properly set and thus S0iX does not work properly in ARL-H/U. This
patch creates a new ARL-H specific device id that is correct and also
adds the D3 fixup to the suspend callback. This way if the PCI devies
drop from D3 to D0 after resume they can be corrected for the next
suspend. Thus there is no dropout in S0iX.

Platforms that do not support SLPC are exempted from the GuC PC support.
The GuC PC does not get initialized, and neither do its BOs get created.
This causes a problem because the GuC PC debugfs file is still being
created. Whenever the file is attempted to read, it causes a NULL
pointer dereference on the supposed BO of the GuC PC.
So, make the creation of SLPC debugfs files conditional to when SLPC
features are supported.

dm_op hypercalls might come from userspace and pass memory addresses as
parameters. The memory addresses typically correspond to buffers
allocated in userspace to hold extra hypercall parameters.
On ARM, when CONFIG_ARM64_SW_TTBR0_PAN is enabled, they might not be
accessible by Xen, as a result ioreq hypercalls might fail. See the
existing comment in arch/arm64/xen/hypercall.S regarding privcmd_call
for reference.
For privcmd_call, Linux calls uaccess_ttbr0_enable before issuing the
hypercall thanks to commit 9cf09d68b89a. We need to do the same for
dm_op. This resolves the problem.

When adding extra memory regions as ballooned pages also adjust the balloon
target, otherwise when the balloon driver is started it will populate
memory to match the target value and consume all the extra memory regions
added.
This made the usage of the Xen `dom0_mem=,max:` command line parameter for
dom0 not work as expected, as the target won't be adjusted and when the
balloon is started it will populate memory straight to the 'max:' value.
It would equally affect domUs that have memory != maxmem.
Kernels built with CONFIG_XEN_UNPOPULATED_ALLOC are not affected, because
the extra memory regions are consumed by the unpopulated allocation driver,
and then balloon_add_regions() becomes a no-op.

When running Xen on iMX8QXP, an Arm SoC without IOMMU, DMA performed via
its eDMA v3 DMA engine fail with a mapping error.
The eDMA performs DMA between RAM and MMIO space, and it's the MMIO side
that cannot be mapped.
MMIO->RAM DMA access cannot be bounce buffered if it would straddle a page
boundary and on Xen the MMIO space is 1:1 mapped for Arm, and x86 PV Dom0.
Cases where MMIO space is not 1:1 mapped, such as x86 PVH Dom0, requires an
IOMMU present to deal with the mapping.
Considering the above the map_resource callback can just be wired to the
existing dma_direct_map_resource() function.
There is nothing to do for unmap so the unmap callback is not needed.

BPF schedulers that use both builtin CPU idle mechanism and
ops.update_idle() may want to use the latter to create interlocking between
ops.enqueue() and CPU idle transitions so that either ops.enqueue() sees the
idle bit or ops.update_idle() sees the task queued somewhere. This can
prevent race conditions where CPUs go idle while tasks are waiting in DSQs.
For such interlocking to work, ops.update_idle() must be called after
builtin CPU masks are updated. Relocate the invocation. Currently, there are
no ordering requirements on transitions from idle and this relocation isn't
expected to make meaningful differences in that direction.
This also makes the ops.update_idle() behavior semantically consistent:
any action performed in this callback should be able to override the
builtin idle state, not the other way around.

Other subsystems may make use of the cgroup hierarchy with the cgroup_bpf
support being one such example. For such a feature, it's useful to be able
to hook into cgroup creation and destruction paths to perform
feature-specific initializations and cleanups.
Add cgroup_lifetime_notifier which generates CGROUP_LIFETIME_ONLINE and
CGROUP_LIFETIME_OFFLINE events whenever cgroups are created and destroyed,
respectively.
The next patch will convert cgroup_bpf to use the new notifier and other
uses are planned.

cgroup_bpf init and exit handling will be moved to a notifier chain. In
prepartion, reorganize cgroup_create() a bit so that the new cgroup is fully
initialized before any outside changes are made.
- cgrp->ancestors[] initialization and the hierarchical nr_descendants and
nr_frozen_descendants updates were in the same loop. Separate them out and
do the former earlier and do the latter later.
- Relocate cgroup_bpf_inherit() call so that it's after all cgroup
initializations are complete.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v6.16
The changes in this release are quite large, mainly in drivers rather
than the core. This is partly due to cleanups that touch a lot of
drivers and partly due to several relatively large new drivers.
- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices, further work is required for these to be
useful in an actual card.
- Conversion of quite a few drivers to newer GPIO APIs.

In commit d69d80484598 ("driver core: have match() callback in struct
bus_type take a const *"), the match bus callback was changed to have
the driver be a const pointer. Unfortunately that const attribute was
thrown away when container_of() is called, which is not correct and was
not caught by the compiler due to how container_of() is implemented.
Fix this up by correctly preserving the const attribute of the driver
passed to the bus match function which requires the hdac_driver match
function to also take a const pointer for the driver structure.

Since the size of struct btintel_dsbr is already known, we can just
start there instead of querying the EFI variable size. If the final
result doesn't match what we expect also fail. This fixes a stack buffer
overflow when the EFI variable is larger than struct btintel_dsbr.

net/mlx5: Convert mlx5 to netdev instance locking
Cosmin Ratiu says:
mlx5 manages multiple netdevices, from basic Ethernet to Infiniband
netdevs. This patch series converts the driver to use netdev instance
locking for everything in preparation for TCP devmem Zero Copy.
Because mlx5 is tightly coupled with the ipoib driver, a series of
changes first happen in ipoib to allow it to work with mlx5 netdevs that
use instance locking:
IB/IPoIB: Enqueue separate work_structs for each flushed interface
IB/IPoIB: Replace vlan_rwsem with the netdev instance lock
IB/IPoIB: Allow using netdevs that require the instance lock
A small patch then avoids dropping RTNL during firmware update:
net/mlx5e: Don't drop RTNL during firmware flash
The main patch then converts all mlx5 netdevs to use instance locking:
net/mlx5e: Convert mlx5 netdevs to instance locking

This patch convert mlx5 to use the new netdev instance lock in addition
to the pre-existing state_lock (and the RTNL).
mlx5e_priv.state_lock was already used throughout mlx5 to protect
against concurrent state modifications on the same netdev, usually in
addition to the RTNL. The new netdev instance lock will eventually
replace it, but for now, it is acquired in addition to the existing
locks in the order RTNL -> instance lock -> state_lock.
All three netdev types handled by mlx5 are converted to the new style of
locking, because they share a lot of code related to initializing
channels and dealing with NAPI, so it's better to convert all three
rather than introduce different assumptions deep in the call stack
depending on the type of device.
Because of the nature of the call graphs in mlx5, it wasn't possible to
incrementally convert parts of the driver to use the new lock, since
either all call paths into NAPI have to possess the new lock if the
*_locked variants are used, or none of them can have the lock.
One area which required extra care is the interaction between closing
channels and devlink health reporter tasks.
Previously, the recovery tasks were unconditionally acquiring the
RTNL, which could lead to deadlocks in these scenarios:
T1: mlx5e_close (== .ndo_stop(), has RTNL) -> mlx5e_close_locked
-> mlx5e_close_channels -> mlx5e_ptp_close
-> mlx5e_ptp_close_queues -> mlx5e_ptp_close_txqsqs
-> mlx5e_ptp_close_txqsq
-> cancel_work_sync(&ptpsq->report_unhealthy_work) waits for
T2: mlx5e_ptpsq_unhealthy_work -> mlx5e_reporter_tx_ptpsq_unhealthy
-> mlx5e_health_report -> devlink_health_report
-> devlink_health_reporter_recover
-> mlx5e_tx_reporter_ptpsq_unhealthy_recover which does:
rtnl_lock(); => Deadlock.
Another similar instance of this is:
T1: mlx5e_close (== .ndo_stop(), has RTNL) -> mlx5e_close_locked
-> mlx5e_close_channels -> mlx5e_ptp_close
-> mlx5e_ptp_close_queues -> mlx5e_ptp_close_txqsqs
-> mlx5e_ptp_close_txqsq
-> cancel_work_sync(&sq->recover_work) waits for
T2: mlx5e_tx_err_cqe_work -> mlx5e_reporter_tx_err_cqe
-> mlx5e_health_report -> devlink_health_report
-> devlink_health_reporter_recover
-> mlx5e_tx_reporter_err_cqe_recover which does:
rtnl_lock(); => Another deadlock.
Fix that by using the same pattern previously done in
mlx5e_tx_timeout_work, where the RTNL was repeatedly tried to be
acquired until either:
a) it is successfully acquired or
b) there's no need for the work to be done any more (channel is being
closed).
Now, for all three recovery tasks, the instance lock is repeatedly tried
to be acquired until successful or the channel/SQ is closed.
As a side-effect, drop the !test_bit(MLX5E_STATE_OPENED, &priv->state)
check from mlx5e_tx_timeout_work, it's weaker than
!test_bit(MLX5E_STATE_CHANNELS_ACTIVE, &priv->state) and unnecessary.
Future patches will introduce new call paths (from netdev queue
management ops) which can close channels (and call cancel_work_sync on
the recovery tasks) without the RTNL lock and only with the netdev
instance lock.
