Pull EFI fixes from Ard Biesheuvel:
- Force the use of SetVirtualAddressMap() on Ampera Altra arm64
machines, which crash in SetTime() if no virtual remapping is used
This is the first time we've added an SMBIOS based quirk on arm64,
but fortunately, we can just call a EFI protocol to grab the type #1
SMBIOS record when running in the stub, so we don't need all the
machinery we have in the kernel proper to parse SMBIOS data.
- Drop a spurious warning on misaligned runtime regions when using 16k
or 64k pages on arm64

In iio_register_sw_trigger_type(), configfs_register_default_group() is
possible to fail, but the entry add to iio_trigger_types_list is not

This leaves wild in iio_trigger_types_list, which can cause page fault

snd_usbmidi_output_open() has a check of the NULL port with
snd_BUG_ON(). snd_BUG_ON() was used as this shouldn't have happened,
but in reality, the NULL port may be seen when the device gives an
invalid endpoint setup at the descriptor, hence the driver skips the
allocation. That is, the check itself is valid and snd_BUG_ON()
should be dropped from there. Otherwise it's confusing as if it were
a real bug, as recently syzbot stumbled on it.

Jeffrey added Multi-MSI support to the pci-hyperv driver by the 4 patches:
08e61e861a0e ("PCI: hv: Fix multi-MSI to allow more than one MSI vector")
455880dfe292 ("PCI: hv: Fix hv_arch_irq_unmask() for multi-MSI")
b4b77778ecc5 ("PCI: hv: Reuse existing IRTE allocation in compose_msi_msg()")
a2bad844a67b ("PCI: hv: Fix interrupt mapping for multi-MSI")
It turns out that the third patch (b4b77778ecc5) causes a performance
regression because all the interrupts now happen on 1 physical CPU (or two
pCPUs, if one pCPU doesn't have enough vectors). When a guest has many PCI
devices, it may suffer from soft lockups if the workload is heavy, e.g.,
see https://lwn.net/ml/linux-kernel/20220804025104.15673-1-decui@microsoft.com/
Commit b4b77778ecc5 itself is good. The real issue is that the hypercall in
hv_irq_unmask() -> hv_arch_irq_unmask() ->
hv_do_hypercall(HVCALL_RETARGET_INTERRUPT...) only changes the target
virtual CPU rather than physical CPU; with b4b77778ecc5, the pCPU is
determined only once in hv_compose_msi_msg() where only vCPU0 is specified;
consequently the hypervisor only uses 1 target pCPU for all the interrupts.
Note: before b4b77778ecc5, the pCPU is determined twice, and when the pCPU
is determined the second time, the vCPU in the effective affinity mask is
used (i.e., it isn't always vCPU0), so the hypervisor chooses different
pCPU for each interrupt.
The hypercall will be fixed in future to update the pCPU as well, but
that will take quite a while, so let's restore the old behavior in
hv_compose_msi_msg(), i.e., don't reuse the existing IRTE allocation for
single-MSI and MSI-X; for multi-MSI, we choose the vCPU in a round-robin
manner for each PCI device, so the interrupts of different devices can
happen on different pCPUs, though the interrupts of each device happen on
some single pCPU.
The hypercall fix may not be backported to all old versions of Hyper-V, so
we want to have this guest side change forever (or at least till we're sure
the old affected versions of Hyper-V are no longer supported).

CQE compression feature improves performance by reducing PCI bandwidth
bottleneck on CQEs write.
Enhanced CQE compression introduced in ConnectX-6 and it aims to reduce
CPU utilization of SW side packets decompression by eliminating the
need to rewrite ownership bit, which is likely to cost a cache-miss, is
replaced by validity byte handled solely by HW.
Another advantage of the enhanced feature is that session packets are
available to SW as soon as a single CQE slot is filled, instead of
waiting for session to close, this improves packet latency from NIC to
host.
Performance:
Following are tested scenarios and reults comparing basic and enahnced
CQE compression.
setup: IXIA 100GbE connected directly to port 0 and port 1 of
ConnectX-6 Dx 100GbE dual port.
Case #1 RX only, single flow goes to single queue:
IRQ rate reduced by ~ 30%, CPU utilization improved by 2%.
Case #2 IP forwarding from port 1 to port 0 single flow goes to
single queue:
Avg latency improved from 60us to 21us, frame loss improved from 0.5% to 0.0%.
Case #3 IP forwarding from port 1 to port 0 Max Throughput IXIA sends
100%, 8192 UDP flows, goes to 24 queues:
Enhanced is equal or slightly better than basic.
Testing the basic compression feature with this patch shows there is
no perfrormance degradation of the basic compression feature.

ASoC: Fixes for v6.1
A relatively large collection of fixes and new platform quirks here,
they're all fairly minor though - the widest possible impact is the fix
to the use of prefixes on regulator names which would have broken any

The latest fix for the non-contiguous memalloc helper changed the
allocation method for a non-IOMMU system to use only the fallback
allocator. This should have worked, but it caused a problem sometimes
when too many non-contiguous pages are allocated that can't be treated
by HD-audio controller.
As a quirk workaround, go back to the original strategy: use
dma_alloc_noncontiguous() at first, and apply the fallback only when
it fails, but only for non-IOMMU case.
We'll need a better fix in the fallback code as well, but this
workaround should paper over most cases.

dt-bindings: net: qcom,ipa: relax some restrictions
The first patch in this series simply removes an unnecessary
requirement in the IPA binding. Previously, if the modem was doing
GSI firmware loading, the firmware name property was required to
*not* be present. There is no harm in having the firmware name be
specified, so this restriction isn't needed.
The second patch restates a requirement on the "memory-region"
property more accurately.
These binding changes have no impact on existing code or DTS files.
These aren't really bug fixes, so no need to back-port.

Either the AP or modem loads GSI firmware. If the modem-init
property is present, the modem loads it. Otherwise, the AP loads
it, and in that case the memory-region property must be defined.
Currently this requirement is expressed as one or the other of the
modem-init or the memory-region property being required. But it's
harmless for the memory-region to be present if the modem is loading
firmware (it'll just be ignored).
Restate the requirement so that the memory-region property is
required only if modem-init is not present.

Commit d8604b209e9b3 ("dt-bindings: net: qcom,ipa: add firmware-name

is more restrictive than necessary.
If the AP loads GSI firmware, the name of the firmware file to use
may optionally be provided via a "firmware-name" property. If the
*modem* loads GSI firmware, "firmware-name" doesn't need to be
supplied--but it's harmless to do so (it will simply be ignored).
Remove the unnecessary restriction, and allow "firware-name" to be

The function mptcp_subflow_process_delegated() uses the input ssk first,
while __mptcp_check_push() invokes the packet scheduler first.
So this patch adds a new parameter named 'first' for the function
__mptcp_subflow_push_pending() to deal with these two cases separately.
With this change, the code that invokes the packet scheduler in the
function __mptcp_check_push() can be removed, and replaced by invoking
__mptcp_subflow_push_pending() directly.

"Several libata generic code fixes for rc5:
- Add missing translation of the SYNCHRONIZE CACHE 16 scsi command as
this command is mandatory for host-managed ZBC drives.
The lack of support for it in libata-scsi was causing issues with
some passthrough applications using ZBC drives (from Shin'ichiro).
- Fix the error path of libata-transport host, port, link and device
attributes initialization (from Yingliang).
- Prevent issuing new commands to a drive that is in the NCQ error
state and undergoing recovery (From Niklas).
This bug went unnoticed for a long time as commands issued to a
drive in error state are aborted immediately and retried by the
scsi layer, hiding the useless abort-and-retry sequence"

We're currently hitting the WARN_ON in mctp_i2c_flow_release:
if (midev->release_count > midev->i2c_lock_count) {
WARN_ONCE(1, "release count overflow");
This may be hit if we expire a flow before sending the first packet it
contains - as we will not be pairing the increment of release_count
(performed on flow release) with the i2c lock operation (only
performed on actual TX).
To fix this, only release a flow if we've encountered it previously (ie,
dev_flow_state does not indicate NEW), as we will mark the flow as
ACTIVE at the same time as accounting for the i2c lock operation. We
also need to add an INVALID flow state, to indicate when we've done the
release.

'aead_req' and 'aead_send' is allocated but not freed in default switch
case. This commit fixes the potential memory leak by freeing them under
the situation.
Note that the default cases here should never be reached as they'd
mean we allowed offloading an unsupported algorithm.

When stmmac_xdp_release() is called, there is a possibility that tx
function is still running on other queues which will lead to tx queue
timed out and reset adapter.
This commit ensure that tx function is not running xdp before release
flow continue to run.

Current driver code will read device tree node information,
and set default values if there is no info provided.
This is not done in non-OF devices leading to SGMII fifo depths being
set to the smallest size.
This patch sets the value to the default value of the PHY as stated in the
PHY datasheet.

A problem about hinic create debugfs failed is triggered with the
following log given:
[ 931.419023] debugfs: Directory 'hinic' with parent '/' already present!
The reason is that hinic_module_init() returns pci_register_driver()
directly without checking its return value, if pci_register_driver()
failed, it returns without destroy the newly created debugfs, resulting
the debugfs of hinic can never be created later.
hinic_module_init()
hinic_dbg_register_debugfs() # create debugfs directory
pci_register_driver()
driver_register()
bus_add_driver()
priv = kzalloc(...) # OOM happened
# return without destroy debugfs directory
Fix by removing debugfs when pci_register_driver() returns error.

Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically,
use put_device() to give up the reference, so that the name can be
freed in kobject_cleanup() when the refcount is 0.
The 'entry' is going to be freed in mISDN_dsp_dev_release(), so the
kfree() is removed. list_del() is called in mISDN_dsp_dev_release(),
so it need be initialized.
