firmware: cs_dsp: Log that a bin file was loaded
Change the message at the start of bin file loading from
cs_dsp_dbg() to cs_dsp_info() so that there is confirmation
in the kernel log that a bin file was loaded, and the name
of the file.

ASoC: mediatek: mt8195: fix use-after-free in driver remove path
During mt8195_afe_init_clock(), mt8195_audsys_clk_register() was called
followed by several other devm functions. At mt8195_afe_deinit_clock()
located at mt8195_afe_pcm_dev_remove(), mt8195_audsys_clk_unregister()
was called.

However, there was an issue with the order in which these functions were
called. Specifically, the remove callback of platform_driver was called
before devres released the resource, resulting in a use-after-free issue
during remove time.

At probe time, the order of calls was:
1. mt8195_audsys_clk_register
2. afe_priv->clk = devm_kcalloc
3. afe_priv->clk[i] = devm_clk_get

At remove time, the order of calls was:
1. mt8195_audsys_clk_unregister
3. free afe_priv->clk[i]
2. free afe_priv->clk

To resolve the problem, we can utilize devm_add_action_or_reset() in
mt8195_audsys_clk_register() so that the remove order can be changed to
3->2->1.

9df6a4870d integrity: Fix possible multiple allocation in integrity_inode_get()
When integrity_inode_get() is querying and inserting the cache, there
is a conditional race in the concurrent environment.

The race condition is the result of not properly implementing
"double-checked locking". In this case, it first checks to see if the
iint cache record exists before taking the lock, but doesn't check
again after taking the integrity_iint_lock.

30c6f0bf95 tcp: fix mishandling when the sack compression is deferred.
In this patch, we mainly try to handle sending a compressed ack
correctly if it's deferred.

Here are more details in the old logic:
When sack compression is triggered in the tcp_compressed_ack_kick(),
if the sock is owned by user, it will set TCP_DELACK_TIMER_DEFERRED
and then defer to the release cb phrase. Later once user releases
the sock, tcp_delack_timer_handler() should send a ack as expected,
which, however, cannot happen due to lack of ICSK_ACK_TIMER flag.
Therefore, the receiver would not sent an ack until the sender's
retransmission timeout. It definitely increases unnecessary latency.

75bd32f5ce wifi: ath10k: Trigger STA disconnect after reconfig complete on hardware restart
Currently, on WCN3990, the station disconnect after hardware recovery is
not working as expected. This is because of setting the
IEEE80211_SDATA_DISCONNECT_HW_RESTART flag very early in the hardware
recovery process even before the driver invokes ieee80211_hw_restart().
On the contrary, mac80211 expects this flag to be set after
ieee80211_hw_restart() is invoked for it to trigger station disconnect.

Set the IEEE80211_SDATA_DISCONNECT_HW_RESTART flag in
ath10k_reconfig_complete() instead to fix this.

The other targets are not affected by this change, since the hardware
params flag is not set.

b43310e44e wifi: ath11k: factory test mode support
Add support to process factory test mode commands (FTM) for calibration.
By default firmware start with NORMAL mode and to process the FTM commands
firmware needs to be restarted in FTM mode using module parameter ftm_mode.
The pre-request is all the radios should be down before starting the test.

When start command ATH11K_TM_CMD_TESTMODE_START is received, ar->state
is set to Test Mode. If the FTM command or event length is greater
than 256 bytes, it will be broken down into multiple segments and
encoded with TLV header if it is segmented commands, else it is sent
to firmware as it is.

On receiving UTF event from firmware, if it is segmented event, the driver
will wait until it receives all the segments and notify the complete
data to user application. In case the segmented sequence are missed or
lost from the firmware, driver will skip the already received partial data.

In case of unsegmented UTF event from firmware, driver notifies the
data to the user application as it comes. Applications handles
the data further.

Command to boot in ftm mode:

insmod ath11k ftm_mode=1

f1061fa641 fbdev: Add initializer macros for struct fb_ops
For framebuffers in I/O and system memory, add macros that set
struct fb_ops to the respective callback functions.

For deferred I/O, add macros that generate callback functions with
damage handling. Add initializer macros that set struct fb_ops to
the generated callbacks.

These macros can remove a lot boilerplate code from fbdev drivers.
The drivers are supposed to use the macro that is required for its
framebuffer. Each macro is split into smaller helpers, so that
drivers with non-standard callbacks can pick and customize callbacks
as needed. There are individual helper macros for read/write, mmap
and drawing.

b3fc95709c iommu/mediatek: Flush IOTLB completely only if domain has been attached
If an IOMMU domain was never attached, it lacks any linkage to the
actual IOMMU hardware. Attempting to do flush_iotlb_all() on it will
result in a NULL pointer dereference. This seems to happen after the
recent IOMMU core rework in v6.4-rc1.

    Unable to handle kernel read from unreadable memory at virtual address 0000000000000018
    Call trace:

Check if the "bank" field has been filled in before actually attempting
the IOTLB flush to avoid it. The IOTLB is also flushed when the device
comes out of runtime suspend, so it should have a clean initial state.

139a57a991 iommu/fsl: Use driver_managed_dma to allow VFIO to work
The FSL driver is mangling the iommu_groups to not have a group for its
PCI bridge/controller (eg the thing passed to fsl_add_bridge()). Robin
says this is so FSL could work with VFIO which would be blocked by having
a probed driver on the platform_device in the same group. This is
supported by comments from FSL:

 https://lore.kernel.org/all/C5ECD7A89D1DC44195F34B25E172658D459471@039-SN2MPN1-013.039d.mgd.msft.net

 ..  PCIe devices share the same device group as the PCI controller. This
  becomes a problem while assigning the devices to the guest, as you are
  required to unbind all the PCIe devices including the controller from the
  host. PCIe controller can't be unbound from the host, so we simply delete
  the controller iommu_group.

However, today, we use driver_managed_dma to allow PCI infrastructure
devices that are 'security safe' to co-exist in groups and still allow
VFIO to work. Set this flag for the fsl_pci_driver.

Change fsl_pamu_device_group() so that it no longer removes the controller
from any groups. For check_pci_ctl_endpt_part() mode this creates an extra
group that contains only the controller.

Otherwise force the controller's single group to be the group of all the
PCI devices on the controller's hose. VFIO continues to work because of
driver_managed_dma.

Remove the iommu_group_remove_device() calls from fsl_pamu and lightly
restructure its fsl_pamu_device_group() function.

5ccf40288c mux: mmio: drop obsolete dependency on COMPILE_TEST
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.
