platform/x86/intel/pmt: fix a crashlog NULL pointer access
Usage of the intel_pmt_read() for binary sysfs, requires a pcidev. The
current use of the endpoint value is only valid for telemetry endpoint
usage.

Without the ep, the crashlog usage causes the following NULL pointer
exception:

BUG: kernel NULL pointer dereference, address: 0000000000000000
Oops: Oops: 0000 [#1] SMP NOPTI

platform/x86: samsung-laptop: Expose charge_types
Support the newly introduced charge_types sysfs attribute as a

dd47fc6769 Octeontx2-af: Add programmed macaddr to RVU pfvf
Octeontx2/CN10k MAC block supports DMAC filters. DMAC filters
can be installed on the interface through ethtool.

When a user installs a DMAC filter, the interface's MAC address
is implicitly added to the filter list. To ensure consistency,
this MAC address must be kept in sync with the pfvf->mac_addr field,
which is used to install MAC-based NPC rules.

This patch updates the pfvf->mac_addr field with the programmed MAC
address and also enables VF interfaces to install DMAC filters.

2094200b5f ibmveth: Add multi buffers rx replenishment hcall support
This patch enables batched RX buffer replenishment in ibmveth by
using the new firmware-supported h_add_logical_lan_buffers() hcall
 to submit up to 8 RX buffers in a single call, instead of repeatedly
calling the single-buffer h_add_logical_lan_buffer() hcall.

During the probe, with the patch, the driver queries ILLAN attributes
to detect IBMVETH_ILLAN_RX_MULTI_BUFF_SUPPORT bit. If the attribute is
present, rx_buffers_per_hcall is set to 8, enabling batched replenishment.
Otherwise, it defaults to 1, preserving the original upstream behavior
 with no change in code flow for unsupported systems.

The core rx replenish logic remains the same. But when batching
is enabled, the driver aggregates up to 8 fully prepared descriptors
into a single h_add_logical_lan_buffers() hypercall. If any allocation
or DMA mapping fails while preparing a batch, only the successfully
prepared buffers are submitted, and the remaining are deferred for
the next replenish cycle.

If at runtime the firmware stops accepting the batched hcall—e,g,
after a Live Partition Migration (LPM) to a host that does not
support h_add_logical_lan_buffers(), the hypercall returns H_FUNCTION.
In that case, the driver transparently disables batching, resets
rx_buffers_per_hcall to 1, and falls back to the single-buffer hcall
in next future replenishments to take care of these and future buffers.

Test were done on systems with firmware that both supports and
does not support the new h_add_logical_lan_buffers hcall.

On supported firmware, this reduces hypercall overhead significantly
over multiple buffers. SAR measurements showed about a 15% improvement
in packet processing rate under moderate RX load, with heavier traffic
seeing gains more than 30%

8d39d6ec4d genirq: Prevent migration live lock in handle_edge_irq()
Yicon reported and Liangyan debugged a live lock in handle_edge_irq()
related to interrupt migration.

If the interrupt affinity is moved to a new target CPU and the interrupt is
currently handled on the previous target CPU for edge type interrupts the
handler might get stuck on the previous target:

CPU 0 (previous target)		CPU 1 (new target)

  handle_edge_irq()
   repeat:
	handle_event()		handle_edge_irq()
			        if (INPROGESS) {
				  set(PENDING);
				  mask();
				  return;
				}
	if (PENDING) {
	  clear(PENDING);
	  unmask();
	  goto repeat;
	}

The migration in software never completes and CPU0 continues to handle the
pending events forever. This happens when the device raises interrupts with
a high rate and always before handle_event() completes and before the CPU0
handler can clear INPROGRESS so that CPU1 sets the PENDING flag over and
over. This has been observed in virtual machines.

Prevent this by checking whether the CPU which observes the INPROGRESS flag
is the new affinity target. If that's the case, do not set the PENDING flag
and wait for the INPROGRESS flag to be cleared instead, so that the new
interrupt is handled on the new target CPU and the previous CPU is released
from the action.

This is restricted to the edge type handler and only utilized on systems,
which use single CPU targets for interrupt affinity.

67c632b4a7 timekeeping: Zero initialize system_counterval when querying time from phc drivers
Most drivers only populate the fields cycles and cs_id of system_counterval
in their get_time_fn() callback for get_device_system_crosststamp(), unless
they explicitly provide nanosecond values.

When the use_nsecs field was added to struct system_counterval, most
drivers did not care.  Clock sources other than CSID_GENERIC could then get
converted in convert_base_to_cs() based on an uninitialized use_nsecs field,
which usually results in -EINVAL during the following range check.

Pass in a fully zero initialized system_counterval_t to cure that.

708243c62e wifi: mac80211: fix unassigned variable access
In ieee80211_latest_active_link_conn_timeout() we loop over all
sta->links in order to compute the timeout expiring last across
all links.

Such timeout is stored in `latest_timeout` which is used in the
time_after() comparison before having been initialized.

Fix this behaviour by initializing the variable to `jiffies` and
adapt surrouding conditions accordingly.

Note that the caller assumed latest_timeout to be 0 if no active
link was found. This is not appropriate because jiffies=0 is a
valid (and recurrent, although not often) point in time.
By using `jiffies` as default value for latest_timeout, we can
fix the caller as well.

f06bedfa62 pNFS/flexfiles: don't attempt pnfs on fatal DS errors
When an applications get killed (SIGTERM/SIGINT) while pNFS client performs a connection
to DS, client ends in an infinite loop of connect-disconnect. This
source of the issue, it that flexfilelayoutdev#nfs4_ff_layout_prepare_ds gets an error
on nfs4_pnfs_ds_connect with status ERESTARTSYS, which is set by rpc_signal_task, but
the error is treated as transient, thus retried.

The issue is reproducible with Ctrl+C the following script(there should be ~1000 files in
a directory, client should must not have any connections to DSes):

```
echo 3 > /proc/sys/vm/drop_caches

for i in *
do
   head -1 $i
done
```

The change aims to propagate the nfs4_ff_layout_prepare_ds error state
to the caller that can decide whatever this is a retryable error or not.
