should either be stored in per-cpu data structures or the updates
should be done using atomic increments.
Since the net_device_core_stats infrastructure is already used in

updates. Update the other counters atomically using DEV_STATS_INC().

net: dsa: realtek: fix LED support for rtl8366
This series fixes the LED support for rtl8366. The existing code was not
tested in a device with switch LEDs and it was using a flawed logic.
The driver now keeps the default LED configuration if nothing requests a
different behavior. This may be enough for most devices. This can be
achieved either by omitting the LED from the device-tree or configuring
all LEDs in a group with the default state set to "keep".
The hardware trigger for LEDs in Realtek switches is shared among all
LEDs in a group. This behavior doesn't align well with the Linux LED
API, which controls LEDs individually. Once the OS changes the
brightness of a LED in a group still triggered by the hardware, the
entire group switches to software-controlled LEDs, even for those not
metioned in the device-tree. This shared behavior also prevents
offloading the trigger to the hardware as it would require an
orchestration between LEDs in a group, not currently present in the LED
API.
The assertion of device hardware reset during driver removal was removed
because it was causing an issue with the LED release code. Devres
devices are released after the driver's removal is executed. Asserting
the reset at that point was causing timeout errors during LED release
when it attempted to turn off the LED.

This commit introduces LED drivers for rtl8366rb, enabling LEDs to be
described in the device tree using the same format as qca8k. Each port
can configure up to 4 LEDs.
If all LEDs in a group use the default state "keep", they will use the
default behavior after a reset. Changing the brightness of one LED,
either manually or by a trigger, will disable the default hardware
trigger and switch the entire LED group to manually controlled LEDs.
Once in this mode, there is no way to revert to hardware-controlled LEDs
(except by resetting the switch).
Software triggers function as expected with manually controlled LEDs.

The necessity of asserting the reset on removal was previously
questioned, as DSA's own cleanup methods should suffice to prevent
traffic leakage[1].
When a driver has subdrivers controlled by devres, they will be
unregistered after the main driver's .remove is executed. If it asserts
a reset, the subdrivers will be unable to communicate with the hardware
during their cleanup. For LEDs, this means that they will fail to turn
off, resulting in a timeout error.

This switch family supports four LEDs for each of its six ports. Each
LED group is composed of one of these four LEDs from all six ports. LED
groups can be configured to display hardware information, such as link
activity, or manually controlled through a bitmap in registers
RTL8366RB_LED_0_1_CTRL_REG and RTL8366RB_LED_2_3_CTRL_REG.
After a reset, the default LED group configuration for groups 0 to 3
indicates, respectively, link activity, link at 1000M, 100M, and 10M, or
RTL8366RB_LED_CTRL_REG as 0x5432. These configurations are commonly used
for LED indications. However, the driver was replacing that
configuration to use manually controlled LEDs (RTL8366RB_LED_FORCE)
without providing a way for the OS to control them. The default
configuration is deemed more useful than fixed, uncontrollable turned-on
LEDs.
The driver was enabling/disabling LEDs during port_enable/disable.
However, these events occur when the port is administratively controlled
(up or down) and are not related to link presence. Additionally, when a
port N was disabled, the driver was turning off all LEDs for group N,
not only the corresponding LED for port N in any of those 4 groups. In
such cases, if port 0 was brought down, the LEDs for all ports in LED
group 0 would be turned off. As another side effect, the driver was
wrongly warning that port 5 didn't have an LED ("no LED for port 5").
Since showing the administrative state of ports is not an orthodox way
to use LEDs, it was not worth it to fix it and all this code was
dropped.
The code to disable LEDs was simplified only changing each LED group to
the RTL8366RB_LED_OFF state. Registers RTL8366RB_LED_0_1_CTRL_REG and
RTL8366RB_LED_2_3_CTRL_REG are only used when the corresponding LED
group is configured with RTL8366RB_LED_FORCE and they don't need to be
cleaned. The code still references an LED controlled by
RTL8366RB_INTERRUPT_CONTROL_REG, but as of now, no test device has
actually used it. Also, some magic numbers were replaced by macros.

Current clone operation could be non-atomic if the destination of a file
is beyond EOF, user could get a file with corrupted (zeroed) data on
crash.
The problem is about preallocations. If you write some data into a file:
[A...B)
and XFS decides to preallocate some post-eof blocks, then it can create
a delayed allocation reservation:
[A.........D)
The writeback path tries to convert delayed extents to real ones by
allocating blocks. If there aren't enough contiguous free space, we can
end up with two extents, the first real and the second still delalloc:
[A....C)[C.D)
After that, both the in-memory and the on-disk file sizes are still B.
If we clone into the range [E...F) from another file:
[A....C)[C.D) [E...F)
then xfs_reflink_zero_posteof() calls iomap_zero_range() to zero out the
range [B, E) beyond EOF and flush it. Since [C, D) is still a delalloc
extent, its pagecache will be zeroed and both the in-memory and on-disk
size will be updated to D after flushing but before cloning. This is
wrong, because the user can see the size change and read the zeroes
while the clone operation is ongoing.
We need to keep the in-memory and on-disk size before the clone
operation starts, so instead of writing zeroes through the page cache
for delayed ranges beyond EOF, we convert these ranges to unwritten and
invalidate any cached data over that range beyond EOF.

A partitioned system has two different PCI VSEC devices per package.
A non-partitioned device has only one PCI VSEC device per package.
The current implementation only supports non partitioned systems.
Each partition maps a set of power domains. Other than reading from
different MMIO regions, there is no change in the SST functionality.
The scope of SST control is still per power domain. Hence user space
does not need to be aware of existence of partitions.
With partitions, existing per package information defined using struct
tpmi_sst_struct is enhanced to store information for both partitions. A
mapping function map_partition_power_domain_id() is introduced, which
maps to correct partition and index. This mapping function is called
in get_instance() and isst_if_clos_assoc(), before indexing into
tpmi_sst_struct->power_domain_info[].
The TPMI core platform info provides partition id and compute die ID
mask for each partition. Use this information to order power domains,
so that compute dies are presented before IO dies to match hardware
defined compute die ID for each CPU.
