Fix several issues with division of negative numbers in the tmp513
driver.
The docs on the DIV_ROUND_CLOSEST macro explain that dividing a negative
value by an unsigned type is undefined behavior. The driver was doing
this in several places, i.e. data->shunt_uohms has type of u32. The
actual "undefined" behavior is that it converts both values to unsigned
before doing the division, for example:
int ret = DIV_ROUND_CLOSEST(-100, 3U);
results in ret == 1431655732 instead of -33.
Furthermore the MILLI macro has a type of unsigned long. Multiplying a
signed long by an unsigned long results in an unsigned long.
So, we need to cast both MILLI and data data->shunt_uohms to long when
using the DIV_ROUND_CLOSEST macro.

Fix E825 initialization
Grzegorz Nitka says:
E825 products have incorrect initialization procedure, which may lead to
initialization failures and register values.
Fix E825 products initialization by adding correct sync delay, checking
the PHY revision only for current PHY and adding proper destination
device when reading port/quad.
In addition, E825 uses PF ID for indexing per PF registers and as
a primary PHY lane number, which is incorrect.

After a job completes, the corresponding pointer in the device must
be set to NULL. Failing to do so triggers a warning when unloading
the driver, as it appears the job is still active. To prevent this,
assign the job pointer to NULL after completing the job, indicating
the job has finished.

Adds a new BO param that keeps the reservation locked after creation.
This removes the need to re-reserve the BO after creation which is a
waste of cycles.
This also fixes a bug in vmw_prime_import_sg_table where the imported
reservation is unlocked twice.

This commit addresses a circular locking dependency issue within the GFX
isolation mechanism. The problem was identified by a warning indicating
a potential deadlock due to inconsistent lock acquisition order.
- The `amdgpu_gfx_enforce_isolation_ring_begin_use` and
`amdgpu_gfx_enforce_isolation_ring_end_use` functions previously
acquired `enforce_isolation_mutex` and called `amdgpu_gfx_kfd_sch_ctrl`,
leading to potential deadlocks. ie., If `amdgpu_gfx_kfd_sch_ctrl` is
called while `enforce_isolation_mutex` is held, and
`amdgpu_gfx_enforce_isolation_handler` is called while `kfd_sch_mutex` is
held, it can create a circular dependency.
By ensuring consistent lock usage, this fix resolves the issue:

v2: Refactor lock handling to resolve circular dependency (Alex)
- Introduced a `sched_work` flag to defer the call to
`amdgpu_gfx_kfd_sch_ctrl` until after releasing
`enforce_isolation_mutex`.
- This change ensures that `amdgpu_gfx_kfd_sch_ctrl` is called outside
the critical section, preventing the circular dependency and deadlock.
- The `sched_work` flag is set within the mutex-protected section if
conditions are met, and the actual function call is made afterward.
- This approach ensures consistent lock acquisition order.

The yt2_1380_fc_serdev_probe() function calls devm_serdev_device_open()
before setting the client ops via serdev_device_set_client_ops(). This
ordering can trigger a NULL pointer dereference in the serdev controller's
receive_buf handler, as it assumes serdev->ops is valid when
SERPORT_ACTIVE is set.
This is similar to the issue fixed in commit 5e700b384ec1

devm_serdev_device_open() was called before fully initializing the
device.
Fix the race by ensuring client ops are set before enabling the port via

Note, serdev_device_set_baudrate() and serdev_device_set_flow_control()
calls should be after the devm_serdev_device_open() call.

pfcp_newlink() links the device to a list in dev_net(dev) instead
of net, where a udp tunnel socket is created.
Even when net is removed, the device stays alive on dev_net(dev).
Then, removing net triggers the splat below. [0]
In this example, pfcp0 is created in ns2, but the udp socket is
created in ns1.
ip netns add ns1
ip netns add ns2
ip -n ns1 link add netns ns2 name pfcp0 type pfcp
ip netns del ns1
Let's link the device to the socket's netns instead.
Now, pfcp_net_exit() needs another netdev iteration to remove
all pfcp devices in the netns.
pfcp_dev_list is not used under RCU, so the list API is converted
to the non-RCU variant.
pfcp_net_exit() can be converted to .exit_batch_rtnl() in net-next.

gtp_newlink() links the gtp device to a list in dev_net(dev).
However, even after the gtp device is moved to another netns,
it stays on the list but should be invisible.
Let's use for_each_netdev_rcu() for netdev traversal in
gtp_genl_dump_pdp().
Note that gtp_dev_list is no longer used under RCU, so list
helpers are converted to the non-RCU variant.

Mesa changed its clear color alignment from 4k to 64 bytes
without informing the kernel side about the change. This
is now likely to cause framebuffer creation to fail.
The only thing we do with the clear color buffer in i915 is:
1. map a single page
2. read out bytes 16-23 from said page
3. unmap the page
So the only requirement we really have is that those 8 bytes
are all contained within one page. Thus we can deal with the
Mesa regression by reducing the alignment requiment from 4k
to the same 64 bytes in the kernel. We could even go as low as
32 bytes, but IIRC 64 bytes is the hardware requirement on
the 3D engine side so matching that seems sensible.
Note that the Mesa alignment chages were partially undone
so the regression itself was already fixed on userspace
side.

Commit c6a837088bed ("drm/amd/display: Fetch the EDID from _DDC if
available for eDP") added function dm_helpers_probe_acpi_edid(), which
fetches the EDID from the BIOS by calling acpi_video_get_edid().
acpi_video_get_edid() returns a pointer to the EDID, but this pointer
does not originate from kmalloc() - it is actually the internal
"pointer" field from an acpi_buffer struct (which did come from
kmalloc()).
dm_helpers_probe_acpi_edid() then attempts to kfree() the EDID pointer,
resulting in memory corruption which leads to random, intermittent
crashes (e.g. 4% of boots will fail with some Oops).
Fix this by allocating a new array (which can be safely freed) for the
EDID data, and correctly freeing the acpi_buffer pointer.
The only other caller of acpi_video_get_edid() is nouveau_acpi_edid():
remove the extraneous kmemdup() here as the EDID data is now copied in
acpi_video_device_EDID().

[Why]
Replay and PSR will cause some video corruption while VRR is enabled.
[How]
1. Disable the Replay and PSR while VRR is enabled.
2. Change the amdgpu_dm_crtc_vrr_active() parameter to const.
Because the function will only read data from dm_crtc_state.

[Why]
The enum DC_PSR_VERSION_SU_1 of psr_version is 1 and
DC_PSR_VERSION_UNSUPPORTED is 0xFFFFFFFF.
The original code may has chance trigger the amdgpu_dm_psr_enable()
while psr version is set to DC_PSR_VERSION_UNSUPPORTED.
[How]
Modify the condition to psr->psr_version == DC_PSR_VERSION_SU_1

Driver always naively assumes, that for PTP purposes, PHY lane to
configure is corresponding to PF ID.
This is not true for some port configurations, e.g.:
- 2x50G per quad, where lanes used are 0 and 2 on each quad, but PF IDs
are 0 and 1
- 100G per quad on 2 quads, where lanes used are 0 and 4, but PF IDs are
0 and 1
Use correct PHY lane assignment by getting and parsing port options.
This is read from the NVM by the FW and provided to the driver with
the indication of active port split.
Remove ice_is_muxed_topo(), which is no longer needed.

Quad registers are read/written incorrectly. E825 devices always use
quad 0 address and differentiate between the PHYs by changing SBQ
destination device (phy_0 or phy_0_peer).
Add helpers for reading/writing PTP registers shared per quad and use
correct quad address and SBQ destination device based on port.

The fence sync logic doesn't handle a fence sync across devices
as it tries to write to a channel offset from one device into
the fence bo from a different device, which won't work so well.
This patch fixes that to avoid using the sync path in the case
where the fences come from different nouveau drm devices.
This works fine on a single device as the fence bo is shared
across the devices, and mapped into each channels vma space,
the channel offsets are therefore okay to pass between sides,
so one channel can sync on the seqnos from the other by using
the offset into it's vma.

Bridges having DRM_BRIDGE_OP_HDMI set in their ->ops are supposed to
rely on the ->supported_formats bitmask to advertise the permitted
colorspaces, including HDMI_COLORSPACE_YUV420.
However, a new flag ->ycbcr_420_allowed has been recently introduced,
which brings the necessity to require redundant and potentially
inconsistent information to be provided on HDMI bridges initialization.
Adjust ->ycbcr_420_allowed for HDMI bridges according to
->supported_formats, right before adding them to the global bridge list.
This keeps the initialization process straightforward and unambiguous,
thereby preventing any further confusion.

The recently added WARN() for deprecated #address-cells and #size-cells
triggered a WARN when of_platform_populate() (which calls
of_address_to_resource()) is used on nodes with non-translatable
addresses. This case is expected to return an error.
Rework the bus matching to allow no match and make the default require
an #address-cells property. That should be safe to do as any platform
missing #address-cells would have a warning already.

When tx_max_frame_size was added to struct ravb_hw_info, no value was
set in ravb_rzv2m_hw_info so the default value of zero was used.
The maximum MTU is set by subtracting from tx_max_frame_size to allow
space for headers and frame checksums. As ndev->max_mtu is unsigned,
this subtraction wraps around leading to a ridiculously large positive
value that is obviously incorrect.
Before tx_max_frame_size was introduced, the maximum MTU was based on
rx_max_frame_size. So, we can restore the correct maximum MTU by copying
the rx_max_frame_size value into tx_max_frame_size for RZ/V2M.

Recalculate features when XDP is detached.
Before:
# ip li set dev eth0 xdp obj xdp_dummy.bpf.o sec xdp
# ip li set dev eth0 xdp off
# ethtool -k eth0 | grep gro
rx-gro-hw: off [requested on]
After:
# ip li set dev eth0 xdp obj xdp_dummy.bpf.o sec xdp
# ip li set dev eth0 xdp off
# ethtool -k eth0 | grep gro
rx-gro-hw: on
The fact that HW-GRO doesn't get re-enabled automatically is just
a minor annoyance. The real issue is that the features will randomly
come back during another reconfiguration which just happens to invoke
netdev_update_features(). The driver doesn't handle reconfiguring
two things at a time very robustly.
Starting with commit 98ba1d931f61 ("bnxt_en: Fix RSS logic in
__bnxt_reserve_rings()") we only reconfigure the RSS hash table
if the "effective" number of Rx rings has changed. If HW-GRO is
enabled "effective" number of rings is 2x what user sees.
So if we are in the bad state, with HW-GRO re-enablement "pending"
after XDP off, and we lower the rings by / 2 - the HW-GRO rings
doing 2x and the ethtool -L doing / 2 may cancel each other out,
and the:
if (old_rx_rings != bp->hw_resc.resv_rx_rings &&
condition in __bnxt_reserve_rings() will be false.
The RSS map won't get updated, and we'll crash with:
BUG: kernel NULL pointer dereference, address: 0000000000000168

ethtool_set_channels+0x18c/0x1d0
As we try to access a freed ring.
The issue is present since XDP support was added, really, but
prior to commit 98ba1d931f61 ("bnxt_en: Fix RSS logic in
__bnxt_reserve_rings()") it wasn't causing major issues.
