In the original design, it is assumed local and peer eswitches have the
same number of vfs. However, in new firmware, local and peer eswitches
can have different number of vfs configured by mlxconfig. In such
configuration, it is incorrect to derive the number of vfs from the
local device's eswitch.
Fix this by updating the peer miss rules add and delete functions to use
the peer device's eswitch and vf count instead of the local device's
information, ensuring correct behavior regardless of vf configuration
differences.

If cmd_exec() is called with callback and mlx5_cmd_invoke() returns an
error, resources allocated in cmd_exec() will not be freed.
Fix the code to release the resources if mlx5_cmd_invoke() returns an
error.

Fixes overlapping buffer allocation for ICSSG peripheral
used for storing packets to be received/transmitted.
There are 3 buffers:
1. Buffer for Locally Injected Packets
2. Buffer for Forwarding Packets
3. Buffer for Host Egress Packets
In existing allocation buffers for 2. and 3. are overlapping causing
packet corruption.
Packet corruption observations:
During tcp iperf testing, due to overlapping buffers the received ack
packet overwrites the packet to be transmitted. So, we see packets on
wire with the ack packet content inside the content of next TCP packet
from sender device.
Details for AM64x switch mode:

Rootcause: missing buffer configuration for Express frames in
function: prueth_fw_offload_buffer_setup()
Details:
Driver implements two distinct buffer configuration functions that are
invoked based on the driver state and ICSSG firmware:-
- prueth_fw_offload_buffer_setup()
- prueth_emac_buffer_setup()
During initialization, driver creates standard network interfaces
(netdevs) and configures buffers via prueth_emac_buffer_setup().
This function properly allocates and configures all required memory
regions including:
- LI buffers
- Express packet buffers
- Preemptible packet buffers
However, when the driver transitions to an offload mode (switch/HSR/PRP),
buffer reconfiguration is handled by prueth_fw_offload_buffer_setup().
This function does not reconfigure the buffer regions required for
Express packets, leading to incorrect buffer allocation.

The fsl_mc_get_endpoint() function uses device_find_child() for
localization, which implicitly calls get_device() to increment the
device's reference count before returning the pointer. However, the
caller dpaa2_switch_port_connect_mac() fails to properly release this
reference in multiple scenarios. We should call put_device() to
decrement reference count properly.
As comment of device_find_child() says, 'NOTE: you will need to drop
the reference with put_device() after use'.

__timerlat_dump_stack() constructs the ftrace stack entry like this:
struct stack_entry *entry;
...
memcpy(&entry->caller, fstack->calls, size);
entry->size = fstack->nr_entries;
Since commit e7186af7fb26 ("tracing: Add back FORTIFY_SOURCE logic to
kernel_stack event structure"), struct stack_entry marks its caller
field with __counted_by(size). At the time of the memcpy, entry->size
contains garbage from the ringbuffer, which under some circumstances is
zero, triggering a kernel panic by buffer overflow.
Populate the size field before the memcpy so that the out-of-bounds
check knows the correct size. This is analogous to
__ftrace_trace_stack().

btrfs is the only user of struct io_uring_cmd_data and its op_data
field. Switch its ->uring_cmd() implementations to store the struct
btrfs_uring_encoded_data * in the struct io_btrfs_cmd, overlayed with
io_uring_cmd's pdu field. This avoids having to touch another cache line
to access the struct btrfs_uring_encoded_data *, and allows op_data and
struct io_uring_cmd_data to be removed.

reparse support
Some servers (including Samba), support the SMB3.1.1 POSIX Extensions (which use reparse
points for handling special files) but do not properly advertise file system attribute
FILE_SUPPORTS_REPARSE_POINTS. Although we don't check for this attribute flag when
querying special file information, we do check it when creating special files which
causes them to fail unnecessarily. If we have negotiated SMB3.1.1 POSIX Extensions
with the server we can expect the server to support creating special files via
reparse points, and even if the server fails the operation due to really forbidding
creating special files, then it should be no problem and is more likely to return a
more accurate rc in any case (e.g. EACCES instead of EOPNOTSUPP).
Allow creating special files as long as the server supports either reparse points
or the SMB3.1.1 POSIX Extensions (note that if the "sfu" mount option is specified
it uses a different way of storing special files that does not rely on reparse points).

The GPIO output functionality does not work as intended.
The ucd9000_gpio_set function should set UCD9000_GPIO_CONFIG_OUT_VALUE
(bit 2) in order to change the output value of the selected GPIO.
Instead UCD9000_GPIO_CONFIG_STATUS (bit 3) is set, but this is a
read-only value. This patch fixes the mistake and provides the intended
functionality of the GPIOs.

Busy extent tracking is primarily used to ensure that freed blocks are
not reused for data allocations before the transaction that deleted them
has been committed to stable storage, and secondarily to drive online
discard. None of the use cases applies to zoned RTGs, as the zoned
allocator can't overwrite blocks before resetting the zone, which already
flushes out all transactions touching the RTGs.
So the busy extent tracking is not needed for zoned RTGs, and also not
called for zoned RTGs. But somehow the code to skip allocating and
freeing the structure got lost during the zoned XFS upstreaming process.
This not only causes these structures to unnecessarily allocated, but can
also lead to memory leaks as the xg_busy_extents pointer in the
xfs_group structure is overlayed with the pointer for the linked list
of to be reset zones.
Stop allocating and freeing the structure to not pointlessly allocate
memory which is then leaked when the zone is reset.

The regulator_set_voltage() function may exhibit unexpected behavior if the
target regulator has a maximum voltage step constraint. With such a
constraint, the regulator core may clamp the requested voltage to a lesser
value, to ensure that the voltage delta stays under the specified limit.
This means that the resulting regulator voltage depends on the current
voltage, as well as the requested range, which invalidates the assumption
that a repeated request for a specific voltage range will amount to a noop.
Considering the case of a regulator with a maximum voltage step constraint
of 1V:
initial voltage: 2.5V
consumer requests 4V
expected result: 3.5V
resulting voltage: 3.5V
consumer requests 4V again
expected result: 4V
actual result: 3.5V
Correct this by repeating attempts to balance the regulator voltage until
the result converges.

When injecting IPIs to a set of harts, the IMSIC IPI support will do a
separate MMIO write to the SETIPNUM_LE register of each target hart. This
means on a platform where IMSIC is trap-n-emulated, there will be N MMIO
traps when injecting IPI to N target harts hence IMSIC IPIs will be slow on
such platforms compared to the SBI IPI extension.
Unfortunately, there is no DT, ACPI, or any other way of discovering
whether the underlying IMSIC is trap-n-emulated. Using MMIO write to the
SETIPNUM_LE register for injecting IPI is purely a software choice in the
IMSIC driver hence add a kernel parameter to allow users to disable IMSIC
IPIs on platforms with trap-n-emulated IMSIC.
