nvme_update_zone_info does (admin queue) I/O to the device and can fail.
We fail to abort the queue limits update if that happen, but really
should avoid with the frozen I/O queue as much as possible anyway.
Split the logic into a helper to query the information that can be
called on an unfrozen queue and one to apply it to the queue limits.

Linux 6.9 made the nvme multipath nodes not properly pick up changes when
the LBA size goes smaller after an nvme format. This is because we now
try to inherit the queue settings for the multipath node entirely from
the individual paths. That is the right thing to do for I/O size
limitations, which make up most of the queue limits, but it is wrong for
changes to the namespace configuration, where we do want to pick up the
new format, which will eventually show up on all paths once they are
re-queried.
Fix this by not inheriting the block size and related fields and always
for updating them.

Commit 0848814aa296 ("drm/i915/dp: Fix connector DSC HW state readout")
moved the DSC HW state readout to a connector specific hook, however
only added the hook for DP MST connectors, not for DP SST ones. Fix
adding the hook for SST connectors as well.
This fixes the following warn on platforms where BIOS enables DSC:

The modeset lock protects the DDC code from concurrent modeset
operations, which use the same registers. Move that code from the
connector helpers into the DDC helpers .pre_xfer() and .post_xfer().
Both, .pre_xfer() and .post_xfer(), enclose the transfer of data blocks
over the I2C channel in the internal I2C function bit_xfer(). Both
calls are executed unconditionally if present. Invoking DDC transfers
from any where within the driver now takes the lock.

Make sure we set suspended=true last to avoid generating an irq storm
in the unlikely case where an IRQ happens between the suspended=true
assignment and the _INT_MASK update.
We also move the mask=0 assignment before writing to the _INT_MASK
register to prevent the thread handler from unmasking the interrupt
behind our back. This means we might lose events if there were some
pending when we get to suspend the IRQ, but that's fine.
The synchronize_irq() we have in the _irq_suspend() path was not
there to make sure all IRQs are processed, just to make sure we don't
have registers accesses coming from the irq handlers after
_irq_suspend() has been called. If there's a need to have all pending
IRQs processed, it should happen before _irq_suspend() is called.

When mapping an IO region, the pseudo-file offset is dependent on the
userspace architecture. panthor_device_mmio_offset() abstracts that
away for us by turning a userspace MMIO offset into its kernel
equivalent, but we were not updating vm_area_struct::vm_pgoff
accordingly, leading us to attach the MMIO region to the wrong file
offset.
This has implications when we start mixing 64 bit and 32 bit apps, but
that's only really a problem when we start having more that 2^43 bytes of
memory allocated, which is very unlikely to happen.
What's more problematic is the fact this turns our
unmap_mapping_range(DRM_PANTHOR_USER_MMIO_OFFSET) calls, which are
supposed to kill the MMIO mapping when entering suspend, into NOPs.
Which means we either keep the dummy flush_id mapping active at all
times, or we risk a BUS_FAULT if the MMIO region was mapped, and the
GPU is suspended after that.
Solve that by patching vm_pgoff early in panthor_mmap(). With
this in place, we no longer need the panthor_device_mmio_offset()
helper.

- No changes

Probably due to a firmware bug Dell TB16 dock announces that one of its
DisplayPort adapters is actually DP IN. Now this is possible and used
with some external GPUs but not likely in this case as we are dealing
with a dock. Anyways the problem is that the driver tries to create a
DisplayPort tunnel between adapters of the same router which then shows
to user that there is no picture on the display (because there are no
available DP OUT adapters on the dock anymore).
Fix this by not creating DisplayPort tunnels between adapters that are
on the same router.

Commit 73d9629e1c8c ("i40e: Do not allow untrusted VF to remove
administratively set MAC") fixed an issue where untrusted VF was
allowed to remove its own MAC address although this was assigned
administratively from PF. Unfortunately the introduced check
is wrong because it causes that MAC filters for other MAC addresses
including multi-cast ones are not removed.
<snip>
if (ether_addr_equal(addr, vf->default_lan_addr.addr) &&
i40e_can_vf_change_mac(vf))
was_unimac_deleted = true;
else
continue;
if (i40e_del_mac_filter(vsi, al->list[i].addr)) {
...
</snip>
The else path with `continue` effectively skips any MAC filter
removal except one for primary MAC addr when VF is allowed to do so.
Fix the check condition so the `continue` is only done for primary
MAC address.

When a dev command times out in MCQ mode, a successfully cleared command
should cause a retry. However, because we currently return 0, the caller
considers the command a success which causes the following error to be
logged: "Invalid offset 0x0 in descriptor IDN 0x9, length 0x0".
Retry if clearing the command was successful.

This series [1] reduced the kmalloc() minimum alignment on arm64 to 8 bytes
(from 128). In libsas, this will cause SMP requests to be 8-byte aligned
through kmalloc() allocation. However, for hisi_sas hardware, all command
addresses must be 16-byte-aligned. Otherwise, the commands fail to be
executed.
ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA
operations, so use ARCH_DMA_MINALIGN as the alignment for SMP request.

When wl suspend error occurs, for example BKOP or SSU timeout, the host
triggers an error handler and returns -EBUSY to break the wl suspend
process. However, it is possible for the runtime PM to enter wl suspend
again before the error handler has finished, and return -EINVAL because the
device is in an error state. To address this, ensure that the rumtime PM
waits for the error handler to finish, or trigger the error handler in such
cases, because returning -EINVAL can cause the I/O to hang.

The myrb and myrs drivers use an odd way of implementing their sysfs files,
calling snprintf() with a fixed length of 32 bytes to print into a page
sized buffer. One of the strings is actually longer than 32 bytes, which
clang can warn about:
drivers/scsi/myrb.c:1906:10: error: 'snprintf' will always be truncated; specified size is 32, but format string expands to at least 34 [-Werror,-Wformat-truncation]
drivers/scsi/myrs.c:1089:10: error: 'snprintf' will always be truncated; specified size is 32, but format string expands to at least 34 [-Werror,-Wformat-truncation]
These could all be plain sprintf() without a length as the buffer is always
long enough. On the other hand, sysfs files should not be overly long
either, so just double the length to make sure the longest strings don't
get truncated here.

There is little point in using %ps to print a value known to be NULL. On
the other hand it makes sense to print the callback symbol in the
'invalid IRQ' message. Correct those two error messages to make more
