[WHY]
These fields are read for the explicit purpose of detecting embedded LTTPRs
(i.e. between host ASIC and the user-facing port), and thus need to
calculate the correct DPCD address offset based on LTTPR count to target
the appropriate LTTPR's DPCD register space with these queries.
[HOW]
Cascaded LTTPRs in a link each snoop and increment LTTPR count when queried
via DPCD read, so an LTTPR embedded in a source device (e.g. USB4 port on a
laptop) will always be addressible using the max LTTPR count seen by the
host. Therefore we simply need to use a recently added helper function to
calculate the correct DPCD address to target potentially embedded LTTPRs
based on the received LTTPR count.

Commit c3be50f754 ("PCI: pciehp: Ignore Presence Detect Changed caused by
DPC") sought to ignore Presence Detect Changed events occurring as a side
effect of Downstream Port Containment.
The commit awaits recovery from DPC and then clears events which occurred
in the meantime. However if the first event seen after DPC is Data Link
Layer State Changed, only that event is cleared and not Presence Detect
Changed. The object of the commit is thus defeated.
That's because pciehp_ist() computes the events to clear based on the local
"events" variable instead of "ctrl->pending_events". The former contains
the events that had occurred when pciehp_ist() was entered, whereas the
latter also contains events that have accumulated while awaiting DPC
recovery.
In practice, the order of PDC and DLLSC events is arbitrary and the delay
in-between can be several milliseconds.
So change the logic to always clear PDC events, even if they come after an
initial DLLSC event.

As part of a wider cleanup trying to get rid of OF specific APIs, an
incorrect (and partially unrelated) cleanup was introduced.
The goal was to replace a device_for_each_chil_node() loop including an
additional condition inside by a macro doing both the loop and the
check on a single line.
The snippet:
device_for_each_child_node(dev, child)
if (fwnode_property_present(child, "gpio-controller"))
continue;
was replaced by:
for_each_gpiochip_node(dev, child)
which expands into:
device_for_each_child_node(dev, child)
for_each_if(fwnode_property_present(child, "gpio-controller"))
This change is actually doing the opposite of what was initially
expected, breaking the probe of this driver, breaking at the same time
the whole boot of Nuvoton platforms (no more console, the kernel WARN()).
Revert these two changes to roll back to the correct behavior.

On some platforms, the UFS-reset pin has no interrupt logic in TLMM but
is nevertheless registered as a GPIO in the kernel. This enables the
user-space to trigger a BUG() in the pinctrl-msm driver by running, for
example: `gpiomon -c 0 113` on RB2.
The exact culprit is requesting pins whose intr_detection_width setting
is not 1 or 2 for interrupts. This hits a BUG() in
msm_gpio_irq_set_type(). Potentially crashing the kernel due to an
invalid request from user-space is not optimal, so let's go through the
pins and mark those that would fail the check as invalid for the irq chip
as we should not even register them as available irqs.
This function can be extended if we determine that there are more
corner-cases like this.

The idea behind this patch was to always let a "master" mtd device
available to anchor runtime PM. Historically, there was no mtd device
representing the whole storage as soon as partitions were coming into
play. The introduction of CONFIG_MTD_PARTITIONED_MASTER allowed to keep
this "master" device, but was not enabled by default to avoid breaking
existing users (otherwise the mtd device numbering would be totally
messed up with an off by 1, at least).
The approach of adding an mtd_master class on top of partitioned mtd
devices is breaking the mtd core in many creative ways, so better think
again this approach and revert the faulty changes for now.

After the following commit from 2024:
commit e37ab73736 ("tcp: fix to allow timestamp undo if no retransmits were sent")
...there was buggy behavior where TCP connections without SACK support
could easily see erroneous undo events at the end of fast recovery or
RTO recovery episodes. The erroneous undo events could cause those
connections to suffer repeated loss recovery episodes and high
retransmit rates.
The problem was an interaction between the non-SACK behavior on these
connections and the undo logic. The problem is that, for non-SACK
connections at the end of a loss recovery episode, if snd_una ==
high_seq, then tcp_is_non_sack_preventing_reopen() holds steady in
CA_Recovery or CA_Loss, but clears tp->retrans_stamp to 0. Then upon
the next ACK the "tcp: fix to allow timestamp undo if no retransmits
were sent" logic saw the tp->retrans_stamp at 0 and erroneously
concluded that no data was retransmitted, and erroneously performed an
undo of the cwnd reduction, restoring cwnd immediately to the value it
had before loss recovery. This caused an immediate burst of traffic
and build-up of queues and likely another immediate loss recovery
episode.
This commit fixes tcp_packet_delayed() to ignore zero retrans_stamp
values for non-SACK connections when snd_una is at or above high_seq,
because tcp_is_non_sack_preventing_reopen() clears retrans_stamp in
this case, so it's not a valid signal that we can undo.
Note that the commit named in the Fixes footer restored long-present
behavior from roughly 2005-2019, so apparently this bug was present
for a while during that era, and this was simply not caught.

Previously, file operations on a file-backed mount used the current
process' credentials to access the backing FD. Attempting to do so on
Android lead to SELinux denials, as ACL rules on the backing file (e.g.
/system/apex/foo.apex) is restricted to a small set of process.
Arguably, this error is redundant and leaking implementation details, as
access to files on a mount is already ACL'ed by path.
Instead, override to use the opener's cred when accessing the backing
file. This makes the behavior similar to a loop-backed mount, which
uses kworker cred when accessing the backing file and does not cause
SELinux denials.

The INVLPGB instruction has limits on how many pages it can invalidate
at once. That limit is enumerated in CPUID, read by the kernel, and
stored in 'invpgb_count_max'. Ranged invalidation, like
invlpgb_kernel_range_flush() break up their invalidations so
that they do not exceed the limit.
However, early boot code currently attempts to do ranged
invalidation before populating 'invlpgb_count_max'. There is a
for loop which is basically:
for (...; addr < end; addr += invlpgb_count_max*PAGE_SIZE)
If invlpgb_kernel_range_flush is called before the kernel has read
the value of invlpgb_count_max from the hardware, the normally
bounded loop can become an infinite loop if invlpgb_count_max is
initialized to zero.
Fix that issue by initializing invlpgb_count_max to 1.
This way INVPLGB at early boot time will be a little bit slower
than normal (with initialized invplgb_count_max), and not an
instant hang at bootup time.

For WMI_REQUEST_VDEV_STAT request, firmware might split response into

case there is no vdev started, this results in that below condition

consequently the requestor would be blocked until time out.

In case of ML connection, currently all useful links are activated at
ASSOC stage:
ieee80211_set_active_links(vif, ieee80211_vif_usable_links(vif))
this results in firmware crash when the number of links activated on the
same device is more than supported.
Since firmware supports activating at most 2 links for a ML connection,
to avoid firmware crash, host needs to select 2 links out of the useful
links. As the assoc link has already been chosen, the question becomes
how to determine partner links. A straightforward principle applied
here is that the resulted combination should achieve the best throughput.
For that purpose, ideally various factors like bandwidth, RSSI etc should
be considered. But that would be too complicate. To make it easy, the
choice is to only take hardware modes into consideration.
The SBS (single band simultaneously) mode frequency range covers 5 GHz
and 6 GHz bands. In this mode, the two individual MACs are both active,
with one working on 5g-high band and the other on 5g-low band (from
hardware perspective 5 GHz and 6 GHz bands are referred to as a 'large'
single 5 GHz band). The DBS (dual band simultaneously) mode covers 2 GHz
band and the 'large' 5 GHz band, with one MAC working on 2 GHz band and
the other working on 5 GHz band or 6 GHz band. Since 5,6 GHz bands could
provide higher bandwidth than 2 GHz band, the preference is given to SBS
mode. Other hardware modes results in only one working MAC at any given
time, so it is chosen only when both SBS are DBS are not possible.
For each hardware mode, if there are more than one partner candidate,
just choose the first one.
For now only single device MLO case is handled as it is easy. Other cases
could be addressed in the future.

In case of two links established on the same device in an ML connection,
depending on device's hardware mode capability, it is possible that both
links fall on the same MAC. Currently, no specific action is taken to
address this but just keep both links active. However this would result
in lower throughput compared to even one link, because switching between
these two links on the resulted MAC significantly impacts throughput.
Check if both links fall in the frequency range of a single MAC. If
so, send WMI_MLO_LINK_SET_ACTIVE_CMDID command to firmware such that
firmware can deactivate one of them. Note the decision of which link
getting deactivated is made by firmware, host only sends the vdev
lists.
