In `nouveau_bo_move_prep`, if `nouveau_mem_map` fails, an error code
should be returned. Currently, it returns zero even if vmm addr is not
correctly mapped.

If reinitialization of one of the GPUs fails after reset, it logs
failure on all subsequent GPUs eventhough they have resumed
successfully.
A sample log where only device at 0000:95:00.0 had a failure -

amdgpu 0000:65:00.0: amdgpu: GPU reset(19) succeeded!

amdgpu 0000:15:00.0: amdgpu: GPU reset end with ret = -5

The point of isolating code that uses kernel mode FPU in separate
compilation units is to ensure that even implicit uses of, e.g., SIMD
registers for spilling occur only in a context where this is permitted,
i.e., from inside a kernel_fpu_begin/end block.
This is important on arm64, which uses -mgeneral-regs-only to build all
kernel code, with the exception of such compilation units where FP or
SIMD registers are expected to be used. Given that the compiler may
invent uses of FP/SIMD anywhere in such a unit, none of its code may be
accessible from outside a kernel_fpu_begin/end block.
This means that all callers into such compilation units must use the
DC_FP start/end macros, which must not occur there themselves. For
robustness, all functions with external linkage that reside there should
call dc_assert_fp_enabled() to assert that the FPU context was set up
correctly.
Fix this for the DCN35, DCN351 and DCN36 implementations.

After GPU reset with VRAM loss, a general protection fault occurs
during user queue restoration when accessing vm_bo->vm after
spinlock release in amdgpu_vm_bo_reset_state_machine.
The root cause is that vm_bo points to the last entry from the
list_for_each_entry loop, but this becomes invalid after the
spinlock is released. Accessing vm_bo->vm at this point leads
to memory corruption.

Pull clk updates from Stephen Boyd:
"There's a bunch of patches here across drivers/clk/ to migrate drivers
to use struct clk_ops::determine_rate() instead of the round_rate()
one so that we can remove the round_rate clk_op entirely. Brian has
taken up that task which nobody else has wanted to do for close to a
decade. Thanks Brian!
This is all prerequisite work to get to the real task of improving the
clk rate setting process. Once we have determine_rate() used
everywhere, we'll be able to do things like chain the rate request
structs in linked lists to order the rate setting operations or add
more parameters without having to change every clk driver in
existence. It's also nice to not have multiple ways to do something
which just causes confusion for clk driver authors. Overall I'm glad
this is getting done.
Beyond this change we also have a tweak to the clk_lookup() function
in the core framework to use hashing on the clk name instead of a clk
tree walk with string comparisons. We _still_ rely on the clk name to
be unique, because historically we've used globally unique strings to
describe the clk tree topology. This tree walk becomes increasingly
slow as more clks are added to the system. Searching from the roots
for a duplicate is simple but pretty dumb and it wastes boot time so
we're using a hash table as an improvement. Ideally we wouldn't rely
on the strings to be unique at all, relegating them to simply debug
information, but that is future work that will likely require some
sort of Kconfig knob indicating strings aren't used for topology
description.
Outside of the core framework changes we have the usual new SoC
support and fixes to clk drivers for things that were discovered once
the clks were used by consumer drivers. Nothing in particular is
jumping out at me in the "misc" pile, except maybe the Amlogic driver
that has gone through a refactoring. That series got a fix from
testing in -next though so it seems likely that things have been
getting good test coverage for a couple weeks already"

Prior to commit b52da4054ee0 ("ipmi: Rework user message limit handling"),
i_ipmi_request() used to increase the user reference counter if the receive
message is provided by the caller of IPMI API functions. This is no longer
the case. However, ipmi_free_recv_msg() is still called and decreases the
reference counter. This results in the reference counter reaching zero,
the user data pointer is released, and all kinds of interesting crashes are
seen.
Fix the problem by increasing user reference counter if the receive message
has been provided by the caller.

PSP support requires a set of cap bits to be set, otherwise an init
error is logged.
But logging an error when PSP cannot be initialized is too much, and not
in line with other features. If a feature cannot be initialized because
it is not supported, that's not an error. An error should only be
printed when the feature cannot be initialized because of an actual
error.

When configuring IPsec packet offload in tunnel mode, the driver tries
to create tunnel reformat objects unconditionally. This is incorrect,
because tunnel mode is only permitted under specific encapsulation
settings, and that decision is already made when the flow table is
created.
The offending commit attempted to block this case in the state add
path, but the check there happens too late and does not prevent the
reformat from being configured.
Fix by taking short reservations for both the eswitch mode and the
encap at the start of state setup. This preserves the block ordering
(mode --> encap) used later: the mode is blocked during RX/TX get, and
the encap is blocked during flow-table creation. This lets us fail
early if either reservation cannot be obtained, it means a mode
transition is underway or a conflicting configuration already owns
encap. If both succeed, the flow-table path later takes the ownership
and the reservations are released on exit.

When creating IPsec flow tables with tunnel mode enabled, the driver
uses mlx5_eswitch_block_encap() to prevent tunnel encapsulation
conflicts across different domains (NIC_RX/NIC_TX and FDB), since the
firmware doesn’t allow both at the same time.
Currently, the driver attempts to reserve tunnel mode unconditionally
for both NIC and FDB IPsec tables. This can lead to conflicting tunnel
mode setups, for example, if a flow table was created in the FDB
domain with tunnel offload enabled, and we later try to create another
one in the NIC, or vice versa.
To resolve this, adjust the blocking logic so that tunnel mode is only
reserved by NIC flows. This ensures that tunnel offload is exclusively
used in either the NIC or the FDB, and avoids unintended offload
conflicts.

Prevent USB runtime PM (autosuspend) for AX88772* in bind.
usbnet enables runtime PM (autosuspend) by default, so disabling it via
the usb_driver flag is ineffective. On AX88772B, autosuspend shows no
measurable power saving with current driver (no link partner, admin
up/down). The ~0.453 W -> ~0.248 W drop on v6.1 comes from phylib powering
the PHY off on admin-down, not from USB autosuspend.
The real hazard is that with runtime PM enabled, ndo_open() (under RTNL)
may synchronously trigger autoresume (usb_autopm_get_interface()) into
asix_resume() while the USB PM lock is held. Resume paths then invoke
phylink/phylib and MDIO, which also expect RTNL, leading to possible
deadlocks or PM lock vs MDIO wake issues.
To avoid this, keep the device runtime-PM active by taking a usage
reference in ax88772_bind() and dropping it in unbind(). A non-zero PM
usage count blocks runtime suspend regardless of userspace policy
(.../power/control - pm_runtime_allow/forbid), making this approach
robust against sysfs overrides.
Holding a runtime-PM usage ref does not affect system-wide suspend;
system sleep/resume callbacks continue to run as before.

The sparx5 driver programs UC/MC/BC flooding in sparx5_update_fwd() by
unconditionally applying bridge_fwd_mask to all flood PGIDs. Any bridge
topology change that triggers sparx5_update_fwd() (for example enslaving
another port) therefore reinstalls flooding in hardware for already
bridged ports, regardless of their per-port flood flags.
This results in clobbering of the flood masks, and desynchronization
between software and hardware: the bridge still reports “flood off” for
the port, but hardware has flooding enabled due to unconditional PGID
reprogramming.
Steps to reproduce:
$ ip link add br0 type bridge
$ ip link set br0 up
$ ip link set eth0 master br0
$ ip link set eth0 up
$ bridge link set dev eth0 flood off
$ ip link set eth1 master br0
$ ip link set eth1 up
At this point, flooding is silently re-enabled for eth0. Software still
shows “flood off” for eth0, but hardware has flooding enabled.
To fix this, flooding is now set explicitly during bridge join/leave,
through sparx5_port_attr_bridge_flags():
On bridge join, UC/MC/BC flooding is enabled by default.
On bridge leave, UC/MC/BC flooding is disabled.
sparx5_update_fwd() no longer touches the flood PGIDs, clobbering
the flood masks, and desynchronizing software and hardware.
Initialization of the flooding PGIDs have been moved to
sparx5_start(). This is required as flooding PGIDs defaults to
0x3fffffff in hardware and the initialization was previously handled
in sparx5_update_fwd(), which was removed.
With this change, user-configured flooding flags persist across bridge
updates and are no longer overridden by sparx5_update_fwd().

When accessing an MDIO register using single-byte smbus accesses, we have to
perform 2 consecutive operations targeting the same address,
first accessing the MSB then the LSB of the 16 bit register:
read_1_byte(addr); <- returns MSB of register at address 'addr'
read_1_byte(addr); <- returns LSB
Some PHY devices present in SFP such as the Broadcom 5461 don't like
seeing foreign i2c transactions in-between these 2 smbus accesses, and
will return the MSB a second time when trying to read the LSB :
read_1_byte(addr); <- returns MSB
i2c_transaction_for_other_device_on_the_bus();
read_1_byte(addr); <- returns MSB again
Given the already fragile nature of accessing PHYs/SFPs with single-byte
smbus accesses, it's safe to say that this Broadcom PHY may not be the
only one acting like this.
Let's therefore hold the i2c bus lock while performing our smbus
transactions to avoid interleaved accesses.

According to the PLIC specification[1], global interrupt sources are
assigned small unsigned integer identifiers beginning at the value 1.
An interrupt ID of 0 is reserved to mean "no interrupt".
The current plic_irq_resume() and plic_irq_suspend() functions incorrectly
start the loop from index 0, which accesses the register space for the
reserved interrupt ID 0.
Change the loop to start from index 1, skipping the reserved
interrupt ID 0 as per the PLIC specification.
This prevents potential undefined behavior when accessing the reserved
register space during suspend/resume cycles.

The MT8196 SoC uses an embedded MCU to control frequencies and power of
the GPU. This controller is referred to as "GPUEB".
It communicates to the application processor, among other ways, through
a mailbox.
The mailbox exposes one interrupt, which appears to only be fired when a
response is received, rather than a transaction is completed. For us,
this means we unfortunately need to poll for txdone.
The mailbox also requires the EB clock to be on when touching any of the
mailbox registers.
Add a simple driver for it based on the common mailbox framework.
