The 8000 series and newer NICs all get hardware timestamps from the MAC
and can provide timestamps on a normal TX queue, rather than via a slow
path through the MC. As such we can use this path for any packet where a
hardware timestamp is requested.
This also enables support for PTP over transports other than IPv4+UDP.

When a driver for an interrupt controller is missing, of_irq_get()
returns -EPROBE_DEFER ad infinitum, causing
fwnode_mdiobus_phy_device_register(), and ultimately, the entire
of_mdiobus_register() call, to fail. In turn, any phy_connect() call
towards a PHY on this MDIO bus will also fail.
This is not what is expected to happen, because the PHY library falls
back to poll mode when of_irq_get() returns a hard error code, and the
MDIO bus, PHY and attached Ethernet controller work fine, albeit
suboptimally, when the PHY library polls for link status. However,
-EPROBE_DEFER has special handling given the assumption that at some
point probe deferral will stop, and the driver for the supplier will
kick in and create the IRQ domain.
Reasons for which the interrupt controller may be missing:
- It is not yet written. This may happen if a more recent DT blob (with
an interrupt-parent for the PHY) is used to boot an old kernel where
the driver didn't exist, and that kernel worked with the
vintage-correct DT blob using poll mode.
- It is compiled out. Behavior is the same as above.
- It is compiled as a module. The kernel will wait for a number of
seconds specified in the "deferred_probe_timeout" boot parameter for
user space to load the required module. The current default is 0,
which times out at the end of initcalls. It is possible that this
might cause regressions unless users adjust this boot parameter.
The proposed solution is to use the driver_deferred_probe_check_state()
helper function provided by the driver core, which gives up after some
-EPROBE_DEFER attempts, taking "deferred_probe_timeout" into consideration.
The return code is changed from -EPROBE_DEFER into -ENODEV or
-ETIMEDOUT, depending on whether the kernel is compiled with support for
modules or not.

The intent of the version check in the mmap ioctl was to maintain
support for existing platforms (i.e., ADL/RPL and earlier), but drop
support on all future igpu platforms. As we've seen on the dgpu side,
the hardware teams are using a more fine-grained numbering system for IP
version numbers these days, so it's possible the version number
associated with our next igpu could be some form of "12.xx" rather than
13 or higher. Comparing against the full ver.release number will ensure
the intent of the check is maintained no matter what numbering the
hardware teams settle on.

Under certain conditions, such as MPI_Abort, the hfi1 cleanup code may
represent the last reference held on the task mm.
hfi1_mmu_rb_unregister() then drops the last reference and the mm is freed
before the final use in hfi1_release_user_pages(). A new task may
allocate the mm structure while it is still being used, resulting in
problems. One manifestation is corruption of the mmap_sem counter leading
to a hang in down_write(). Another is corruption of an mm struct that is
in use by another task.

To move the list iterator variable into the list_for_each_entry_*() macro
in the future it should be avoided to use the list iterator variable after
the loop body.
To *never* use the list iterator variable after the loop it was concluded
to use a separate iterator variable instead of a found boolean.
This removes the need to use a found variable and simply checking if the
variable was set, can determine if the break/goto was hit.

This is due to that free_irq_cpu_rmap() is always being called
*after* (devm_)free_irq() and thus it tries to work with IRQ descs
already freed. For example, on device reset the driver frees the
rmap right before allocating a new one (the splat above).
Make rmap creation and freeing function symmetrical with
{request,free}_irq() calls i.e. do that on ifup/ifdown instead
of device probe/remove/resume. These operations can be performed
independently from the actual device aRFS configuration.
Also, make sure ice_vsi_free_irq() clears IRQ affinity notifiers
only when aRFS is disabled -- otherwise, CPU rmap sets and clears
its own and they must not be touched manually.

Since we have generic function to count GPIO controller nodes
under a given device, there is no need to open code it. Replace
custom code by gpiochip_node_count() call.

When removing the adt7470 module, a warning might be printed:
do not call blocking ops when !TASK_RUNNING; state=1
set at [<ffffffffa006052b>] adt7470_update_thread+0x7b/0x130 [adt7470]
This happens because adt7470_update_thread() can leave the kthread in
TASK_INTERRUPTIBLE state when the kthread is being stopped before
the call of set_current_state(). Since kthread_exit() might sleep in
exit_signals(), the warning is printed.
Fix that by using schedule_timeout_interruptible() and removing
the call of set_current_state().
This causes TASK_INTERRUPTIBLE to be set after kthread_should_stop()
which might cause the kthread to exit.

The of_find_compatible_node() function returns a node pointer with

In SetHalDefVar8188EUsb() there is only the case HAL_DEF_DBG_DM_FUNC.
Move its functionality to a new static function in ioctl_linux.c and
remove SetHalDefVar8188EUsb(). This is part of the ongoing effort to
get rid of the unwanted hal layer.

Replace if else statement with min_t or max_t macros to increase
readability and conform to Linux kernel coding style. The _t versions
of the macros must be used to avoid applying typeof to the bit fields
pPeerHTCap->MaxRxAMPDUFactor, and pPeerHTCap->MPDUDensity.
Using u32 assures the reader that the value with not be truncated
without having to look up the types of the variables involved.

It currently assumes that there are always four channels, it would
cause the error if there is actually less than four channels. Change
that by getting number of channel from device tree.
For backwards-compatibility, it uses the default value (i.e. 4) when
there is no 'dma-channels' information in dts.
