Pull devicetree fixes from Rob Herring:
- Fix a memory leak for of_pci_add_properties() failure case. Then fix
the introduced UAF.
- Add missing IORESOURCE_MEM flag on of_reserved_mem_region_to_resource()
- Add already in use vendor prefix "eswin"
- Clarify "of of" comment in of_match_device(). After many years of
drive-by patches dropping the 2nd "of" (which referred to
OpenFirmware), a correct patch finally arrived

`McstFramesRcvdOk` counts the number of received multicast packets, and
it reports the value correctly.
However, reading `McstFramesRcvdOk` clears the register to zero. As a
result, the driver was reporting only the packets since the last read,
instead of the accumulated total.
Fix this by updating the multicast statistics accumulatively instaed of
instantaneously.

Before configuring the NIX block, the AF driver initiates the
"NIX block X2P bus calibration" and verifies that NIX interfaces
such as CGX and LBK are active and functioning correctly.
On few silicon variants(CNF10KA and CNF10KB), X2P calibration failures
have been observed on some CGX blocks that are not mapped to the NIX block.
Since both NIX-mapped and non-NIX-mapped CGX blocks share the same
VENDOR,DEVICE,SUBSYS_DEVID, it's not possible to skip probe based on
these parameters.
This patch introuduces "is_cgx_mapped_to_nix" API to detect and skip
probe of non NIX mapped CGX blocks.

Commit 4edf1505b76d ("ata: ahci: Disallow LPM policy control for
external ports") introduced disabling link power management (LPM) for
ports that are advertized as external/hotplug capable. This is necessary
to force the maximum power policy (ATA_LPM_MAX_POWER) onto the port link
to ensure that the hotplug capability of the port is functional.
However, doing so blindly for all ports can prevent systems from going
into a low power state, even if the external/hotplug ports on the system
are unused. E.g., a laptop may see the internal SATA slot of a docking
station as an external hotplug capable port, and in such case, the user
may prefer to not use the port and to favor instead enabling LPM
to allow the laptop to transition to low power states.
Since there is no easy method to automatically detect such choice,
introduce the new mask_port_ext module parameter to allow a user to
ignore the external/hotplug capability of a port. The format for this
parameter value is identical to the format used for the mask_port_map
parameter: a mask can be defined for all AHCI adapters of a system or
for a particular adapters identified with their PCI IDs (bus:dev.func
format).
The function ahci_get_port_map_mask() is renamed to ahci_get_port_mask()
and modified to return a mask, either for the port map mask of an
adapter (to ignore ports) or for the external/hotplug capability of an
adapter. Differentiation between map_port_mask and map_port_ext_mask is
done by passing the parameter string to ahci_get_port_mask() as a second
argument.
To be consistent with this change, the function
ahci_apply_port_map_mask() is renamed ahci_port_mask() and changed to
return a mask value.
The mask for the external/hotplug capability for an adapter, if defined
by the map_port_ext_mask parameter, is stored in the new field
mask_port_ext of struct ahci_host_priv. ahci_mark_external_port() is
modified to not set the ATA_PFLAG_EXTERNAL flag for a port if
hpriv->mask_port_ext includes the number of the port. In such case,
an information message is printed to notify that the external/hotplug
capability is being ignored.

When synthesizing build-ids, for build ID mmap2 events, they will be
added for data mmaps if -d/--data is specified. The files opened for
their build IDs may block on the open causing perf to hang during
synthesis. There is some robustness in existing calls to
filename__read_build_id by checking the file path is to a regular
file, which unfortunately fails for symlinks. Rather than adding more
is_regular_file calls, switch filename__read_build_id to take a
"block" argument and specify O_NONBLOCK when this is false. The
existing is_regular_file checking callers and the event synthesis
callers are made to pass false and thereby avoiding the hang.

The ice_adapter structure is used by the ice driver to connect multiple
physical functions of a device in software. It was introduced by
commit 0e2bddf9e5f9 ("ice: add ice_adapter for shared data across PFs on
the same NIC") and is primarily used for PTP support, as well as for
handling certain cross-PF synchronization.
The original design of ice_adapter used PCI address information to
determine which devices should be connected. This was extended to support
E825C devices by commit fdb7f54700b1 ("ice: Initial support for E825C
hardware in ice_adapter"), which used the device ID for E825C devices
instead of the PCI address.
Later, commit 0093cb194a75 ("ice: use DSN instead of PCI BDF for
ice_adapter index") replaced the use of Bus/Device/Function addressing with
use of the device serial number.
E825C devices may appear in "Dual NAC" configuration which has multiple
physical devices tied to the same clock source and which need to use the
same ice_adapter. Unfortunately, each "NAC" has its own NVM which has its
own unique Device Serial Number. Thus, use of the DSN for connecting
ice_adapter does not work properly. It "worked" in the pre-production
systems because the DSN was not initialized on the test NVMs and all the
NACs had the same zero'd serial number.
Since we cannot rely on the DSN, lets fall back to the logic in the
original E825C support which used the device ID. This is safe for E825C
only because of the embedded nature of the device. It isn't a discreet
adapter that can be plugged into an arbitrary system. All E825C devices on
a given system are connected to the same clock source and need to be
configured through the same PTP clock.
To make this separation clear, reserve bit 63 of the 64-bit index values as
a "fixed index" indicator. Always clear this bit when using the device
serial number as an index.
For E825C, use a fixed value defined as the 0x579C E825C backplane device
ID bitwise ORed with the fixed index indicator. This is slightly different
than the original logic of just using the device ID directly. Doing so
prevents a potential issue with systems where only one of the NACs is
connected with an external PHY over SGMII. In that case, one NAC would
have the E825C_SGMII device ID, but the other would not.
Separate the determination of the full 64-bit index from the 32-bit
reduction logic. Provide both ice_adapter_index() and a wrapping
ice_adapter_xa_index() which handles reducing the index to a long on 32-bit
systems. As before, cache the full index value in the adapter structure to
warn about collisions.
This fixes issues with E825C not initializing PTP on both NACs, due to
failure to connect the appropriate devices to the same ice_adapter.

The ice_cfg_tx_topo function attempts to apply Tx scheduler topology
configuration based on NVM parameters, selecting either a 5 or 9 layer
topology.
As part of this flow, the driver acquires the "Global Configuration Lock",
which is a hardware resource associated with programming the DDP package
to the device. This "lock" is implemented by firmware as a way to
guarantee that only one PF can program the DDP for a device. Unlike a
traditional lock, once a PF has acquired this lock, no other PF will be
able to acquire it again (including that PF) until a CORER of the device.
Future requests to acquire the lock report that global configuration has
already completed.
The following flow is used to program the Tx topology:
* Read the DDP package for scheduler configuration data
* Acquire the global configuration lock
* Program Tx scheduler topology according to DDP package data
* Trigger a CORER which clears the global configuration lock
This is followed by the flow for programming the DDP package:
* Acquire the global configuration lock (again)
* Download the DDP package to the device
* Release the global configuration lock.
However, if configuration of the Tx topology fails, (i.e.
ice_get_set_tx_topo returns an error code), the driver exits
ice_cfg_tx_topo() immediately, and fails to trigger CORER.
While the global configuration lock is held, the firmware rejects most
AdminQ commands, as it is waiting for the DDP package download (or Tx
scheduler topology programming) to occur.
The current driver flows assume that the global configuration lock has been
reset by CORER after programming the Tx topology. Thus, the same PF
attempts to acquire the global lock again, and fails. This results in the
driver reporting "an unknown error occurred when loading the DDP package".
It then attempts to enter safe mode, but ultimately fails to finish
ice_probe() since nearly all AdminQ command report error codes, and the
driver stops loading the device at some point during its initialization.
The only currently known way that ice_get_set_tx_topo() can fail is with
certain older DDP packages which contain invalid topology configuration, on
firmware versions which strictly validate this data. The most recent
releases of the DDP have resolved the invalid data. However, it is still
poor practice to essentially brick the device, and prevent access to the
device even through safe mode or recovery mode. It is also plausible that
this command could fail for some other reason in the future.
We cannot simply release the global lock after a failed call to
ice_get_set_tx_topo(). Releasing the lock indicates to firmware that global
configuration (downloading of the DDP) has completed. Future attempts by
this or other PFs to load the DDP will fail with a report that the DDP
package has already been downloaded. Then, PFs will enter safe mode as they
realize that the package on the device does not meet the minimum version
requirement to load. The reported error messages are confusing, as they
indicate the version of the default "safe mode" package in the NVM, rather
than the version of the file loaded from /lib/firmware.
Instead, we need to trigger CORER to clear global configuration. This is
the lowest level of hardware reset which clears the global configuration
lock and related state. It also clears any already downloaded DDP.
Crucially, it does *not* clear the Tx scheduler topology configuration.
Refactor ice_cfg_tx_topo() to always trigger a CORER after acquiring the
global lock, regardless of success or failure of the topology
configuration.
We need to re-initialize the HW structure when we trigger the CORER. Thus,
it makes sense for this to be the responsibility of ice_cfg_tx_topo()
rather than its caller, ice_init_tx_topology(). This avoids needless
re-initialization in cases where we don't attempt to update the Tx
scheduler topology, such as if it has already been programmed.
There is one catch: failure to re-initialize the HW struct should stop
ice_probe(). If this function fails, we won't have a valid HW structure and
cannot ensure the device is functioning properly. To handle this, ensure
ice_cfg_tx_topo() returns a limited set of error codes. Set aside one
specifically, -ENODEV, to indicate that the ice_init_tx_topology() should
fail and stop probe.
Other error codes indicate failure to apply the Tx scheduler topology. This
is treated as a non-fatal error, with an informational message informing
the system administrator that the updated Tx topology did not apply. This
allows the device to load and function with the default Tx scheduler
topology, rather than failing to load entirely.
Note that this use of CORER will not result in loops with future PFs
attempting to also load the invalid Tx topology configuration. The first PF
will acquire the global configuration lock as part of programming the DDP.
Each PF after this will attempt to acquire the global lock as part of
programming the Tx topology, and will fail with the indication from
firmware that global configuration is already complete. Tx scheduler
topology configuration is only performed during driver init (probe or
devlink reload) and not during cleanup for a CORER that happens after probe
completes.

Pentium 4's which are INTEL_P4_PRESCOTT (model 0x03) and later have
a constant TSC. This was correctly captured until commit fadb6f569b10
("x86/cpu/intel: Limit the non-architectural constant_tsc model checks").
In that commit, an error was introduced while selecting the last P4
model (0x06) as the upper bound. Model 0x06 was transposed to
INTEL_P4_WILLAMETTE, which is just plain wrong. That was presumably a
simple typo, probably just copying and pasting the wrong P4 model.
Fix the constant TSC logic to cover all later P4 models. End at
INTEL_P4_CEDARMILL which accurately corresponds to the last P4 model.

object_err() reports details of an object for further debugging, such as
the freelist pointer, redzone, etc. However, if the pointer is invalid,
attempting to access object metadata can lead to a crash since it does
not point to a valid object.
One known path to the crash is when alloc_consistency_checks()
determines the pointer to the allocated object is invalid because of a
freelist corruption, and calls object_err() to report it. The debug code
should report and handle the corruption gracefully and not crash in the
process.
In case the pointer is NULL or check_valid_pointer() returns false for
the pointer, only print the pointer value and skip accessing metadata.

On commit 9286dfd5735b ("platform/x86: asus-wmi: Fix spurious rfkill on
UX8406MA"), Mathieu adds a quirk for the Zenbook Duo to ignore the code
0x5f (WLAN button disable). On that laptop, this code is triggered when
the device keyboard is attached.
On the ASUS ROG Z13 2025, this code is triggered when pressing the side
button of the device, which is used to open Armoury Crate in Windows.
As this is becoming a pattern, where newer Asus laptops use this keycode
for emitting events, let's convert the wlan ignore quirk to instead
allow emitting codes, so that userspace programs can listen to it and
so that it does not interfere with the rfkill state.
With this patch, the Z13 wil emit KEY_PROG3 and the Duo will remain
unchanged and emit no event. While at it, add a quirk for the Z13 to
switch into tablet mode when removing the keyboard.

Currently, the ignore_key_wlan quirk applies to keycodes 0x5D, 0x5E, and
0x5F. However, the relevant code for the Asus Zenbook Duo is only 0x5F.
Since this code is emitted by other Asus devices, such as from the Z13
for its ROG button, remove the extra codes before expanding the quirk.
For the Duo devices, which are the only ones that use this quirk, there
should be no effect.

In the current design, the `pm8008_regulator_get_voltage_sel()` callback
can return a negative value if the raw voltage value is read as 0 uV from
the PMIC HW register. This can cause the probe to fail when the
`machine_constraints_voltage()` check is called during the regulator
registration flow.
Fix this by using the helper `regulator_map_voltage_linear_range()` to
convert the raw value to a voltage selector inside the mentioned get
voltage selector function. This ensures that the value returned is always
within the defined range.

In gicv5_irs_of_init_affinity() a WARN_ON() is triggered if:
1) a phandle in the "cpus" property does not correspond to a valid OF
node
2 a CPU logical id does not exist for a given OF cpu_node
#1 is a firmware bug and should be reported as such but does not warrant a
WARN_ON() backtrace.
#2 is not necessarily an error condition (eg a kernel can be booted with
nr_cpus=X limiting the number of cores artificially) and therefore there
is no reason to clutter the kernel log with WARN_ON() output when the
condition is hit.
