The value of llc_testlink_time is set to the value stored in
net->ipv4.sysctl_tcp_keepalive_time when linkgroup init. The value of
sysctl_tcp_keepalive_time is already jiffies, so we don't need to
multiply by HZ, which would cause smc_link->llc_testlink_time overflow,
and test_link send flood.

MTU change is refused whenever the value of new MTU is bigger than
the max packet bytes that fits in NFP Cluster Target Memory (CTM).
However, an eBPF program doesn't always need to access the whole
packet data.
The maximum direct packet access (DPA) offset has always been
caculated by verifier and stored in the max_pkt_offset field of prog
aux data.

[Why]
A deadlock in the kernel occurs when we fallback from the V3 to V2
add_topology_to_display or remove_topology_to_display because they
both try to acquire the dtm_mutex but recursive locking isn't
supported on mutex_lock().
[How]
Make the mutex_lock/unlock more fine grained and move them up such that
they're only required for the psp invocation itself.

[WHY]
On certain configs, SMU clock table voltages don't match which cause parser
to behave incorrectly by leaving dcfclk and socclk table entries unpopulated.
[HOW]
Currently the function that finds the corresponding clock for a given voltage
only checks for exact voltage level matches. In the case that no match gets
found, parser now falls back to searching for the max clock which meets the
requested voltage (i.e. its corresponding voltage is below requested).

make: [Makefile:1868: arch/nios2/boot/dts] Error 2 (ignored)
This is seen with compile tests since those enable NIOS2_DTB_SOURCE_BOOL,
which in turn enables NIOS2_DTB_SOURCE. This causes the build error
because the default value for NIOS2_DTB_SOURCE is an empty string.
Disable NIOS2_DTB_SOURCE_BOOL for compile tests to avoid the error.

As the width of packets number registers is 32 bits, they needs at most
10 characters for decimal data printing, but now the string spaces is not
enough, so this patch fixes it.

Currently, the workqueue of hclge/hclgevf is executed on
the CPU that initiates scheduling requests by default. In
stress scenarios, the CPU may be busy and workqueue scheduling
is completed after a long period of time. To avoid this
situation and implement proper scheduling, use the WQ_UNBOUND
mode instead. In this way, the workqueue can be performed on
a relatively idle CPU.

If a TP port is configured by follow steps:
1.ethtool -s ethx autoneg off speed 100 duplex full
2.ethtool -A ethx rx on tx on
3.ethtool -s ethx autoneg on(rx&tx negotiated pause results are off)
4.ethtool -s ethx autoneg off speed 100 duplex full
In step 3, driver will set rx&tx pause parameters of hardware to off as
pause parameters negotiated with link partner are off.
After step 4, the "ethtool -a ethx" command shows both rx and tx pause
parameters are on. However, pause parameters of hardware are still off
and port has no flow control function actually.
To fix this problem, if autoneg is disabled, driver uses its saved
parameters to restore pause of hardware. If the speed is not changed in
this case, there is no link state changed for phy, it will cause the pause
parameter is not taken effect, so we need to force phy to go down and up.

Commit a33df75c63 ("block: use an xarray for disk->part_tbl") modified
the method to check partition existence in host-aware zoned block
devices from disk_has_partitions() helper function call to empty check
of xarray disk->part_tbl. However, disk->part_tbl always has single
entry for disk->part0 and never becomes empty. This resulted in the
host-aware zoned devices always judged to have partitions, and it made
the sysfs queue/zoned attribute to be "none" instead of "host-aware"
regardless of partition existence in the devices.
This also caused DEBUG_LOCKS_WARN_ON(lock->magic != lock) for
sdkp->rev_mutex in scsi layer when the kernel detects host-aware zoned
device. Since block layer handled the host-aware zoned devices as non-
zoned devices, scsi layer did not have chance to initialize the mutex
for zone revalidation. Therefore, the warning was triggered.
To fix the issues, call the helper function disk_has_partitions() in
place of disk->part_tbl empty check. Since the function was removed with
the commit a33df75c63, reimplement it to walk through entries in the
xarray disk->part_tbl.

Nobody cares about iov iterators state if we return -EIOCBQUEUED, so as
the we now have __blkdev_direct_IO_async(), which gets pages only once,
we can skip expensive iov_iter_advance(). It's around 1-2% of all CPU
spent.
