While freeing SQB pointers to aura, driver first memcpy to
target address and then triggers lmtst operation to free pointer
to the aura. We need to ensure(by adding dmb barrier)that memcpy
is finished before pointers are freed to the aura. This patch also
adds the missing sq context structure entry in debugfs.

AF modifies all the rules destined for VF to use
the action same as default RSS action. This fixup
was needed because AF only installs default rules with
RSS action. But the action in rules installed by a PF
for its VFs should not be changed by this fixup.
This is because action can be drop or direct to
queue as specified by user(ntuple filters).
This patch fixes that problem.

HID: vivaldi: Minor cleanups

If we ever see a touch report with contact count data we initialize
several variables used to read the contact count in the pre-report
phase. These variables are never reset if we process a report which
doesn't contain a contact count, however. This can cause the pre-
report function to trigger a read of arbitrary memory (e.g. NULL
if we're lucky) and potentially crash the driver.
This commit restores resetting of the variables back to default
"none" values that were used prior to the commit mentioned
below.

AES hardware may internally re-classify a contact that it thought was
intentional as a palm. Intentional contacts are reported as "down" with
the confidence bit set. When this re-classification occurs, however, the
state transitions to "up" with the confidence bit cleared. This kind of
transition appears to be legal according to Microsoft docs, but we do
not handle it correctly. Because the confidence bit is clear, we don't
call `wacom_wac_finger_slot` and update userspace. This causes hung
touches that confuse userspace and interfere with pen arbitration.
This commit adds a special case to ignore the confidence flag if a contact
is reported as removed. This ensures we do not leave a hung touch if one
of these re-classification events occured. Ideally we'd have some way to
also let userspace know that the touch has been re-classified as a palm
and needs to be canceled, but that's not possible right now :)

These two values go hand-in-hand and must be valid for the driver to
behave correctly. We are currently lazy about updating the values and
rely on the "expected" code flow to take care of making sure they're
valid at the point they're needed. The "expected" flow changed somewhat
with commit f8b6a74719 ("HID: wacom: generic: Support multiple tools
per report"), however. This led to problems with the DTH-2452 due (in
part) to *all* contacts being fully processed -- even those past the
expected contact count. Specifically, the received count gets reset to
0 once all expected fingers are processed, but not the expected count.
The rest of the contacts in the report are then *also* processed since
now the driver thinks we've only processed 0 of N expected contacts.
Later commits such as 7fb0413baa (HID: wacom: Use "Confidence" flag to
prevent reporting invalid contacts) worked around the DTH-2452 issue by
skipping the invalid contacts at the end of the report, but this is not
a complete fix. The confidence flag cannot be relied on when a contact
is removed (see the following patch), and dealing with that condition
re-introduces the DTH-2452 issue unless we also address this contact
count laziness. By resetting expected and received counts at the same
time we ensure the driver understands that there are 0 more contacts
expected in the report. Similarly, we also make sure to reset the
received count if for some reason we're out of sync in the pre-report
phase.

This is the third and final of a series of small pull requests that

we're withdrawing all variants of the ALLOCSP and FREESP ioctls from
XFS' userspace API. This might be a little premature since we've only
just removed the functionality, but as I pointed out in the last pull
request, nobody (including fstests) noticed that it was broken for 20
years.
In response to the patch, we received a single comment from someone
who stated that they 'augment' the ioctl for their own purposes, but
otherwise acquiesced to the withdrawal. I still want to try to clobber
these old ioctl definitions in 5.17.

"Remove the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl families.
This is the second of a series of small pull requests that perform
some long overdue housecleaning of XFS ioctls. This time, we're
vacating the implementation of all variants of the ALLOCSP and FREESP
ioctls, which are holdovers from EFS in Irix, circa 1993. Roughly
equivalent functionality have been available for both ioctls since
2.6.25 (April 2008):
- XFS_IOC_FREESP ftruncates a file.
- XFS_IOC_ALLOCSP is the equivalent of fallocate.
As noted in the fix patch for CVE 2021-4155, the ALLOCSP ioctl has
been serving up stale disk blocks since 2000, and in 21 years
**nobody** noticed. On those grounds I think it's safe to vacate the
implementation.
Note that we lose the ability to preallocate and truncate relative to
the current file position, but as nobody's ever implemented that for
the VFS, I conclude that it's not in high demand.

MPJ ipv6 selftests currently lack per link route to the server
net. Additionally, ipv6 subflows endpoints are created without any
interface specified. The end-result is that in ipv6 self-tests
subflows are created all on the same link, leading to expected delays
and sporadic self-tests failures.
Fix the issue by adding the missing setup bits.

Signed-off-by: Helge Deller <deller@gmx.de>
Usually palo (the PA-RISC boot loader) will check at boot time if the
machine/firmware was configured to use the serial line (ttyS0, SERIAL_x)
or the graphical display (tty0, graph) as default output device and add
the correct "console=ttyS0" or "console=tty0" Linux kernel parameter to
the kernel command line when starting the Linux kernel.
But the kernel could also have been started via the HP-UX boot loader
or directly in qemu, in which cases the console parameter is missing.
This patch fixes this problem by adding the correct console= parameter
if it's missing in the current kernel command line.

Commit 0f153a1b81 ("usb: chipidea: Set the DT node on the child
device") caused the child device to match on the parent driver
instead of the child's driver since the child's DT node pointer matched.
The worst case result is a loop of the parent driver probing another
instance and creating yet another child device eventually exhausting the
stack. If the child driver happens to match first, then everything works
fine.
A device sharing the DT node should never do DT based driver matching,
so let's simply check of_node_reused in of_match_device() to prevent
that.

The 'interrupts' properties takes an irq number, not a phandle, and
'interrupt-parent' isn't needed in examples.

The YAML DT encoding has leaked into some array properties. Properties
which are defined as an array should have a schema that's just an array.
That means there should only be a single level of 'minItems',
'maxItems', and/or 'items'.

Change i40e_update_vsi_stats and struct i40e_vsi to use u64 fields to match
the width of the stats counters in struct i40e_rx_queue_stats.
Update debugfs code to use the correct format specifier for u64.

Fix for failed to init adminq: -53 while VF is resetting via MAC
address changing procedure.
Added sync module to avoid reading deadbeef value in reinit adminq
during software reset.
Without this patch it is possible to trigger VF reset procedure
during reinit adminq. This resulted in an incorrect reading of
value from the AQP registers and generated the -53 error.

This was caused by PF queue pile fragmentation due to
flow director VSI queue being placed right after main VSI.
Because of this main VSI was not able to resize its
queue allocation for XDP resulting in no queues allocated
for main VSI when XDP was turned on.
Fix this by always allocating last queue in PF queue pile
for a flow director VSI.
