There is an existing comedi_request_region(dev, start, len) function
used by COMEDI drivers for legacy devices to request an I/O port region
starting at a specified base address (which must be non-zero) and with a
specified length. It uses request_region(). On success, it sets
dev->iobase and dev->iolen and returns 0. There is a alternative
function __comedi_request_region(dev, start, len) which does the same
thing without setting dev->iobase and dev->iolen.
Most hardware devices have restrictions on the allowed I/O port base
address and alignment, so add new functions
comedi_check_request_region(dev, start, len, minstart, maxend, minalign)
and __comedi_check_request_region(dev, start, len, minstart, maxend,
minalign) to perform these additional checks. Turn the original
functions into static inline wrapper functions that call the new
functions.

Rather than querying the output device for its address in
mctp_local_output, set up the source address when we're populating the
dst structure. If no address is assigned, use MCTP_ADDR_NULL.
This will allow us more flexibility when routing for NULL-source-eid
cases. For now though, we still reject a NULL source address in the
output path.
We need to update the tests a little, so that addresses are assigned
before we do the dst lookups.

Making ->d_rcu and (then) ->d_child overlapping dates back to
2006; anon unions support had been added to gcc only in 4.6

Most of the places using d_alias are loops iterating through all aliases for
given inode; introduce a helper macro (for_each_alias(dentry, inode))
and convert open-coded instances of such loop to it.
They are easier to read that way and it reduces the noise on the next steps.
You _must_ hold inode->i_lock over that thing.

Replace the coarse USB device lock with a dedicated offload_lock
spinlock to reduce contention during offload operations. Use
offload_pm_locked to synchronize with PM transitions and replace
the legacy offload_at_suspend flag.
Optimize usb_offload_get/put by switching from auto-resume/suspend
to pm_runtime_get_if_active(). This ensures offload state is only
modified when the device is already active, avoiding unnecessary
power transitions.

This patch introduces support for operating the Cadence USBSSP (cdnsp)
controller in a peripheral-only mode, bypassing the Dual-Role Device (DRD)
logic.
The change in BAR indexing (from BAR 2 to BAR 1) is a direct
consequence of switching from 64-bit to 32-bit addressing in the
Peripheral-only configuration.
Tested on PCI platform with Device-only configuration. Platform-side
changes are included to support the PCI glue layer's property injection.

Current CC designs don't place a vIOMMU in front of untrusted devices.
Instead, the DMA API forces all untrusted device DMA through swiotlb
bounce buffers (is_swiotlb_force_bounce()) which copies data into
shared memory on behalf of the device.
When a caller has already arranged for the memory to be shared
via set_memory_decrypted(), the DMA API needs to know so it can map
directly using the unencrypted physical address rather than bounce
buffering. Following the pattern of DMA_ATTR_MMIO, add
DMA_ATTR_CC_SHARED for this purpose. Like the MMIO case, only the
caller knows what kind of memory it has and must inform the DMA API
for it to work correctly.

STM32 Firewall bus for v7.1, round 1
Highlights:
----------
Stm32 SoCs embed debug peripherals such as Coresight. These peripherals
can monitor the activity of the cores. Because of that, they can be
used only if some features in the debug configuration are enabled.
Else, errors or firewall exceptions can be observed. Similarly to
the ETZPC(on stm32mp1x platforms) or the RIFSC(on stm32mp2x platforms),
debug-related peripherals access can be assessed at bus level to
prevent these issues from happening.
The debug configuration can only be accessed by the secure world.
That means that a service must be implemented in the secure world for
the kernel to check the firewall configuration. On OpenSTLinux, it is
done through a Debug access PTA in OP-TEE [1].
To represent the debug peripherals present on a dedicated debug bus,
create a debug bus node in the device tree and the associated driver
that will interact with this PTA.
Plus some fixes.

On systems where many CPUs share one LLC, unbound workqueues using
WQ_AFFN_CACHE collapse to a single worker pool, causing heavy spinlock
contention on pool->lock. For example, Chuck Lever measured 39% of
cycles lost to native_queued_spin_lock_slowpath on a 12-core shared-L3
NFS-over-RDMA system.
The existing affinity hierarchy (cpu, smt, cache, numa, system) offers
no intermediate option between per-LLC and per-SMT-core granularity.
Add WQ_AFFN_CACHE_SHARD, which subdivides each LLC into groups of at
most wq_cache_shard_size cores (default 8, tunable via boot parameter).
Shards are always split on core (SMT group) boundaries so that
Hyper-Threading siblings are never placed in different pods. Cores are
distributed across shards as evenly as possible -- for example, 36 cores
in a single LLC with max shard size 8 produces 5 shards of 8+7+7+7+7
cores.
The implementation follows the same comparator pattern as other affinity
scopes: precompute_cache_shard_ids() pre-fills the cpu_shard_id[] array
from the already-initialized WQ_AFFN_CACHE and WQ_AFFN_SMT topology,
and cpus_share_cache_shard() is passed to init_pod_type().
Benchmark on NVIDIA Grace (72 CPUs, single LLC, 50k items/thread), show
cache_shard delivers ~5x the throughput and ~6.5x lower p50 latency
compared to cache scope on this 72-core single-LLC system.

All data will be copied through the fallback path. The user is also
expected to use ZCRX_CTRL_FLUSH_RQ to handle overflows as it normally
should even with a netdev, but it becomes even more relevant as there
will likely be no one to automatically pick up buffers.
Apart from that, it follows the zcrx uapi for the I/O path, and is

The newly introduced arch_timer_context::direct field is a bit pointless,
as it is always set on timers that are... err... direct, while
we already have a way to get to that by doing a get_map() operation.
Additionally, this field is:
- only set when get_map() is called
- never cleared
and the single point where it is actually checked doesn't call get_map()
at all.
At this stage, it is probably better to just kill it, and rely on
get_map() to give us the correct information.

Currently, PL4 and MSR-based RAPL PMU support are detected using
separate CPU ID tables (pl4_support_ids and pmu_support_ids) in the
MSR driver probe path. This creates a maintenance burden since adding
a new CPU requires updates in two places: the rapl_ids table and one
or both of these capability tables.
Consolidate PL4 and PMU capability information directly into
struct rapl_defaults by adding msr_pl4_support and msr_pmu_support
flags. This allows per-CPU capability to be expressed in a single
place alongside other per-CPU defaults, eliminating the duplicate
CPU ID tables entirely.
No functional changes are intended.

RAPL primitive information varies across different RAPL interfaces
(MSR, TPMI, MMIO). Keeping them in the common code adds no benefit, but
requires interface-specific handling logic and makes the common layer
unnecessarily complex.
Move the primitive info infrastructure to the shared header to allow
interface drivers to configure RAPL primitives. Specific changes:
1. Move struct rapl_primitive_info, enum unit_type, and
PRIMITIVE_INFO_INIT macro to intel_rapl.h.
2. Change the @rpi field in struct rapl_if_priv from void * to
struct rapl_primitive_info * to improve type safety and eliminate
unnecessary casts.
No functional changes. This is a preparatory refactoring to allow
interface drivers to supply their own RAPL primitive settings.

A recent change exposed a bug in the error path: if
freq_qos_add_request(boost_freq_req) fails, min_freq_req may remain a
valid pointer even though it was never successfully added. During policy
teardown, this leads to an unconditional call to
freq_qos_remove_request(), triggering a WARN.
The current design allocates all three freq_req objects together, making
the lifetime rules unclear and error handling fragile.
Simplify this by allocating the QoS freq_req objects at policy
allocation time. The policy itself is dynamically allocated, and two of
the three requests are always needed anyway. This ensures consistent
lifetime management and eliminates the inconsistent state in failure
paths.

Qualcomm driver fixes for v7.0
Fix the length of the PD restart reason string in pd-mapper to avoid
QMI decoding errors, resulting in the notification being dropped.
Fix the newly introduce handling of TBT/USB4 notifications in pmic_glink
altmode driver, as it broke the handling of non-TBT/USB4 DisplayPort
unplug events.

Reset controller fixes for v7.0, part 2
* Decouple spacemit K3 reset lines that were incorrectly coupled
together as one, but are in fact separate resets in hardware.
* Fix a double free in the reset_add_gpio_aux_device() error path.
This has already been fixed on reset/next by commit a9b95ce36de4
("reset: gpio: add a devlink between reset-gpio and its consumer").

It doesn't really make sense to keep u32 fields to be marked as const.
Having the const fields prevents their modification in the driver. Instead
the whole struct can be defined as const, if it is constant.

Addresses two issues in the TH1520 AON firmware protocol driver:
1. Fix a potential buffer overflow where the code used unsafe pointer
arithmetic to access the 'mode' field through the 'resource' pointer
with an offset. This was flagged by Smatch static checker as:
"buffer overflow 'data' 2 <= 3"
2. Replace custom RPC_SET_BE* and RPC_GET_BE* macros with standard
kernel endianness conversion macros (cpu_to_be16, etc.) for better
portability and maintainability.
The functionality was re-tested with the GPU power-up sequence,
confirming the GPU powers up correctly and the driver probes
successfully.

Move vlv_iosf_sb_reg.h to include/drm/intel/vlv_iosf_sb_regs.h. Use
_regs.h suffix to align better with other register headers. Move enum
vlv_iosf_sb_unit there as well, breaking the final include tie related
to IOSF sideband between display and i915 core.
With this, we can completely remove the xe compat vls_iosf_sb*.h
headers.

Remove another direct dependency from display to i915 core by moving the
VLV IOSF sideband calls to the display parent interface. Xe doesn't need
this, so it'll remain optional and NULL.

print_hex_dump_bytes() claims to be a simple wrapper around

means no output is printed if (dynamic) DEBUG is disabled.

reserve_bootmem_region() is only called from
memmap_init_reserved_pages() and it was in mm/mm_init.c because of its
dependecies on static init_deferred_page().
Since init_deferred_page() is not static anymore, move
reserve_bootmem_region(), rename it to memmap_init_reserved_range() and
make it static.
Update the comment describing it to better reflect what the function
does and drop bogus comment about reserved pages in free_bootmem_page().
Update memblock test stubs to reflect the core changes.
