Flow for creating Tx topology is the same as for VF port representors,
but the devlink port is stored in different place (sf->devlink_port).
When creating VF devlink lock isn't taken, when creating subfunction it
is. Setting Tx topology function needs to take this lock, check if it
was taken before to not do it twice.

Keep the same flow of port representor creation, but instead of general
attach function create helpers for specific representor type.
Store function pointer for add and remove representor.
Type of port representor can be also known based on VSI type, but it
is more clean to have it directly saved in port representor structure.
Add devlink lock for whole port representor creation and destruction.

Implement devlink port handlers responsible for ethernet type devlink
subfunctions. Create subfunction devlink port and setup all resources
needed for a subfunction netdev to operate. Configure new VSI for each
new subfunction, initialize and configure interrupts and Tx/Rx resources.
Set correct MAC filters and create new netdev.
For now, subfunction is limited to only one Tx/Rx queue pair.
Only allocate new subfunction VSI with devlink port new command.
Allocate and free subfunction MSIX interrupt vectors using new API
calls with pci_msix_alloc_irq_at and pci_msix_free_irq.
Support both automatic and manual subfunction numbers. If no subfunction
number is provided, use xa_alloc to pick a number automatically. This
will find the first free index and use that as the number. This reduces
burden on users in the simple case where a specific number is not
required. It may also be slightly faster to check that a number exists
since xarray lookup should be faster than a linear scan of the dyn_ports
xarray.

Now reshape supports two ways: with backup file or without backup file.
For the situation without backup file, it needs to change data offset.
It doesn't need systemd service mdadm-grow-continue. So it can finish
the reshape job in one process environment. It can know the new level
from mdadm --grow command and can change to new level after reshape
finishes.
For the situation with backup file, it needs systemd service
mdadm-grow-continue to monitor reshape progress. So there are two process
envolved. One is mdadm --grow command whick kicks off reshape and wakes
up mdadm-grow-continue service. The second process is the service, which
doesn't know the new level from the first process.
In kernel space mddev->new_level is used to record the new level when
doing reshape. This patch adds a new interface to help mdadm update
new_level and sync it to metadata. Then mdadm-grow-continue can read the
right new_level.

When resctrl is built on architectures without __cpuid_count()
support, build fails. resctrl uses __cpuid_count() defined in
kselftest.h.
Even though the problem is seen while building resctrl on aarch64,
this error can be seen on any platform that doesn't support CPUID.
CPUID is a x86/x86-64 feature and code paths with CPUID asm commands
will fail to build on all other architectures.
All others tests call __cpuid_count() do so from x86/x86_64 code paths
when _i386__ or __x86_64__ are defined. resctrl is an exception.
Fix the problem by defining __cpuid_count() only when __i386__ or
__x86_64__ are defined in kselftest.h and changing resctrl to call
__cpuid_count() only when __i386__ or __x86_64__ are defined.

The zram_table_entry::flags member is of type long and uses 8 bytes on a
64bit architecture. With a PAGE_SIZE of 256KiB we have PAGE_SHIFT of 18
which in turn leads to __NR_ZRAM_PAGEFLAGS = 27. This still fits in an
ordinary integer.
By reducing the size of `flags' to four bytes, the size of the struct
goes back to 16 bytes. The padding between the lock and ac_time (if
enabled) is also gone.
Make zram_table_entry::flags an unsigned int and update the build test
to reflect the change.

The bit spinlock disables preemption. The spinlock_t lock becomes a sleeping
lock on PREEMPT_RT and it can not be acquired in this context. In this locked
section, zs_free() acquires a zs_pool::lock, and there is access to
zram::wb_limit_lock.
Add a spinlock_t for locking. Keep the set/ clear ZRAM_LOCK bit after
the lock has been acquired/ dropped. The size of struct zram_table_entry
increases by 4 bytes due to lock and additional 4 bytes padding with
CONFIG_ZRAM_TRACK_ENTRY_ACTIME enabled.

BFQ has been lacking active maintenance for approximately two years, and it
was recently transitioned to the Orphan state. However, there are still
many users, I have decided to step forward and assume the role of
maintainer to ensure continued support and development.
While I may not be the one with the most extensive knowledge of BFQ's
internals, I have been actively involved in its development since 2021.
Moreover, our team continues to rigorously test BFQ in downstream kernels,
ensuring it's stability and performance. Despite my confidence to maintain
BFQ, I believe it is prudent to classify its state as "Odd Fixes" to
accurately reflect my relatively new position as the maintainer.
By assuming this responsibility, I am committed to providing the necessary
support and addressing any issues that may arise with BFQ. As time
progresses, we will reassess the situation and determine the appropriate
state.

Allow to disable ACPI PM Timer on suspend and enable on resume. A
disabled timer helps optimise power consumption when the system is
suspended. On resume the timer is only reactivated if it was activated
prior to suspend, so unless the ACPI PM timer is enabled in the BIOS,
this won't change anything.
The ACPI PM timer is used by Intel's iTCO/wdat_wdt watchdog to drive the
watchdog, so it doesn't need to run during suspend.

Due to the lack of checks on the clc array, if the firmware supports
more clc configuration, it will cause illegal memory access.

Replace comma between expressions with semicolons.
Using a ',' in place of a ';' can have unintended side effects.
Although that is not the case here, it is seems best to use ';'
unless ',' is intended.
Found by inspection.
No functional change intended.
Compile tested only.

In multi-channel scenarios, the granted channel must be aborted before
suspending. Otherwise, the firmware will be put into a wrong state,
resulting in an association failure after resuming.
With this patch, the granted channel will be aborted before suspending
if necessary.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `struct_group_tagged()`
helper to create a new tagged `struct mt76_connac2_mcu_rxd_hdr`.
This structure groups together all the members of the flexible
`struct mt76_connac2_mcu_rxd` except the flexible array.
As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct mt76_connac2_mcu_rxd` to `struct
mt76_connac2_mcu_rxd_hdr`.
We also want to ensure that when new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement `struct mt76_connac2_mcu_rxd_hdr`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
So, with these changes, fix the following warnings:
drivers/net/wireless/mediatek/mt76/mt7915/mcu.h:32:37: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
