Move the generic implementations from asm-generic/xor.h to
per-implementaion .c files in lib/raid. This will build them
unconditionally even when an architecture forces a specific
implementation, but as we'll need at least one generic version for the
static_call optimization later on we'll pay that price.
Note that this would cause the second xor_block_8regs instance created by
arch/arm/lib/xor-neon.c to be generated instead of discarded as dead code,
so add a NO_TEMPLATE symbol to disable it for this case.

Drop the pretty confusing historic XOR_TRY_TEMPLATES and
XOR_SELECT_TEMPLATE, and instead let the architectures provide a
arch_xor_init that calls either xor_register to register candidates or
xor_force to force a specific implementation.

In a subsequent patch, the regs_refine_cond_op and reg_bounds_sync
functions will be called in is_branch_taken instead of reg_set_min_max,
to simulate each branch's outcome. Since they will run before we branch
out, these two functions will need to work on temporary registers for
the two branches.
This refactoring patch prepares for that change, by introducing the
temporary registers on bpf_verifier_env and using them in
reg_set_min_max.
This change also allows us to save one fake_reg slot as we don't need to
allocate an additional temporary buffer in case of a BPF_K condition.
Finally, you may notice that this patch removes the check for
"false_reg1 == false_reg2" in reg_set_min_max. That check was introduced
in commit d43ad9da8052 ("bpf: Skip bounds adjustment for conditional
jumps on same scalar register") to avoid an invariant violation. Given
that "env->false_reg1 == env->false_reg2" doesn't make sense and
invariant violations are addressed in a subsequent commit, this patch
just removes the check.

Implement the standard ETHTOOL_PHY_DOWNSHIFT tunable for the LAN88xx
PHY. This allows runtime configuration of the auto-downshift feature
via ethtool:
ethtool --set-phy-tunable eth0 downshift on count 3
The LAN88xx PHY supports downshifting from 1000BASE-T to 100BASE-TX
after 2-5 failed auto-negotiation attempts. Valid count values are
2, 3, 4 and 5.
This is based on an earlier downstream implementation by Phil Elwell.

"stdrng" is needed only in "FIPS mode". Therefore, make
crypto_stdrng_get_bytes() delegate to either the normal Linux RNG or to
"stdrng", depending on the current mode.
This will eliminate the need to built the SP800-90A DRBG and its
dependencies into CRYPTO_FIPS=n kernels.

All callers of crypto_get_default_rng() use the following sequence:
crypto_get_default_rng()
crypto_rng_get_bytes(crypto_default_rng, ...)
crypto_put_default_rng()
While it may have been intended that callers amortize the cost of
getting and putting the "default RNG" (i.e. "stdrng") over multiple
calls, in practice that optimization is never used. The callers just
want a function that gets random bytes from the "stdrng".
Therefore, add such a function: crypto_stdrng_get_bytes().
Importantly, this decouples the callers from the crypto_rng API. That
allows a later commit to make this function simply call
get_random_bytes_wait() unless the kernel is in "FIPS mode".

firmware: tegra: Changes for v7.1-rc1
This introduces a new API for the BPMP to be pass along a specifier from
DT when getting a reference from a phandle. This is used to reference
specific instances of the PCI controller on Tegra264. The ABI header for
BPMP is updated to the latest version and BPMP APIs now use the more
intuitive ENODEV instead of the non SUSV4 ENOTSUPP error code for stub
implementations.

cpufreq_cpu_get() can sleep on PREEMPT_RT in presence of concurrent
writer(s), however amd-pstate depends on fetching the cpudata via the
policy's driver data which necessitates grabbing the reference.
Since schedutil governor can call "cpufreq_driver->update_perf()"
during sched_tick/enqueue/dequeue with rq_lock held and IRQs disabled,
fetching the policy object using the cpufreq_cpu_get() helper in the
scheduler fast-path leads to "BUG: scheduling while atomic" on
PREEMPT_RT [1].
Pass the cached cpufreq policy object in sg_policy to the update_perf()
instead of just the CPU. The CPU can be inferred using "policy->cpu".
The lifetime of cpufreq_policy object outlasts that of the governor and
the cpufreq driver (allocated when the CPU is onlined and only reclaimed
when the CPU is offlined / the CPU device is removed) which makes it
safe to be referenced throughout the governor's lifetime.

This patchset contains few fixes for the bugs hit during testing with
Monza EVK platform
- around array out of bounds access on dai ids which keep extending but
the drivers seems to have hardcoded some numbers, fix this and clean
the mess up
- fix few issues discovered while trying to shut down dsp.
- flooding rpmsg with write requests due to not resetting queue pointer,
fix this resetting the pointer in trigger stop.
- possible multiple graph opens which can result in open failures.
Apart from this few new enhancements to the dsp side
- add new LPI MI2S and senary dai entries
- handle pipewire and Displayport issues by moving graph start to
trigger level, which should fix outstanding pipewire and DP issues on
Qualcomm SoCs.
- remove some unnessary loops in hot path
- support early memory map on DSP.
Tested this on top of linux-next on VENTUNO-Q platform.

xHCI hardware maintains its endpoint state between add_endpoint()
and drop_endpoint() calls followed by successful check_bandwidth().
So does the driver.
Core may call endpoint_disable() during xHCI endpoint life, so don't
clear host_ep->hcpriv then, because this breaks endpoint_reset().
If a driver calls usb_set_interface(), submits URBs which make host
sequence state non-zero and calls usb_clear_halt(), the device clears
its sequence state but xhci_endpoint_reset() bails out. The next URB
malfunctions: USB2 loses one packet, USB3 gets Transaction Error or
may not complete at all on some (buggy?) HCs from ASMedia and AMD.
This is triggered by uvcvideo on bulk video devices.
The code was copied from ehci_endpoint_disable() but it isn't needed
here - hcpriv should only be NULL on emulated root hub endpoints.
It might prevent resetting and inadvertently enabling a disabled and
dropped endpoint, but core shouldn't try to reset dropped endpoints.
Document xhci requirements regarding hcpriv. They are currently met.

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.

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.

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
useful for testing, experimentation, and potentially for the copy
receive path in the future if improved.

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.
