Rename original txgbe_misc_irq_handle() to txgbe_misc_irq_thread_fn()
since it is the handle thread to wake up. And add the primary handler
to deal the case of MSI/INTx, because there is a schedule NAPI poll.

When using MSI or INTx interrupts, request_irq() for pdev->irq will
conflict with request_threaded_irq() for txgbe->misc.irq, to cause
system crash. So remove txgbe_request_irq() for MSI/INTx case, and
rename txgbe_request_msix_irqs() since it only request for queue irqs.
Add wx->misc_irq_domain to determine whether the driver creates an IRQ
domain and threaded request the IRQs.

When using MSI/INTx interrupts, wx->num_q_vectors is uninitialized.
Thus there will be kernel panic in wx_alloc_q_vectors() to allocate

The global hci_hotkey_quickstart quirk flag is tested in
toshiba_acpi_enable_hotkeys() before the quirk flag is properly
initialized based on SMBIOS data. This causes the quirk to be
applied to all models, some of which behave erratically as a
result.
Fix this by initializing the global quirk flags during module
initialization before registering the ACPI driver. This also
allows us to mark toshiba_dmi_quirks[] as __initconst.

As it turns out, there is a large number of out-of-tree DTSes (in
OpenWrt project) that used to specify incorrect (active high) polarity
for the Lantiq reset GPIO, so to keep compatibility while they are
being updated a quirk for force the polarity low is needed. Luckily
these old DTSes used nonstandard name for the property ("gpio-reset" vs
"reset-gpios") so the quirk will not hurt if there are any new devices
that need inverted polarity as they can specify the right polarity in
their DTS when using the standard "reset-gpios" property.
Additionally the condition to enable the transition from standard to
non-standard reset GPIO property name was inverted and the replacement
name for the property was not correct. Fix this as well.

On vPro systems, the configuration of the I219-LM to achieve power
gating and S0ix residency is split between the driver and the CSME FW.
It was discovered that in some scenarios, where the network cable is
connected and then disconnected, S0ix residency is not always reached.
This was root-caused to a subset of I219-LM register writes that are not
performed by the CSME FW. Therefore, the driver should perform these
register writes on corporate setups, regardless of the CSME FW state.
This was discovered on Meteor Lake systems; however it is likely to
appear on other platforms as well.

[Why]
Potential out of bounds access in dml2_calculate_rq_and_dlg_params()
because the value of out_lowest_state_idx used as an index for FCLKChangeSupport
array can be greater than 1.
[How]
Currently dml2 core specifies identical values for all FCLKChangeSupport
elements. Always use index 0 in the condition to avoid out of bounds access.

We need to ensure to take into account cursor prefetch BW in
mode support or we may pass ModeQuery but fail an actual flip
which will cause a hang. Flip may fail because the cursor_pre_bw
is populated during mode programming (and mode programming is
never called prior to ModeQuery).

Commit 2f7b1d8b5505 ("clk: mediatek: Do a runtime PM get on controllers
during probe") enabled runtime PM for all mediatek clock controllers,
but this introduced an issue on the resume path.
If a device resumes earlier than the clock controller and calls
clk_prepare() when runtime PM is enabled on the controller, it will end
up calling clk_pm_runtime_get(). But the subsequent
pm_runtime_resume_and_get() call will fail because the runtime PM is
temporarily disabled during suspend.
To workaround this, introduce a need_runtime_pm flag and only enable it
on mt8183-mfgcfg, which is the driver that observed deadlock previously.
Hopefully mt8183-cfgcfg won't run into the issue at the resume stage
because the GPU should have stopped rendering before the system calls
suspend.

Add a function, ata_port_free(), that is used to free a ata_port,
including its struct members. It makes sense to keep the code related to
freeing a ata_port in its own function, which will also free all the
struct members of struct ata_port.

If the ata_port_alloc() call in ata_host_alloc() fails,
ata_host_release() will get called.
However, the code in ata_host_release() tries to free ata_port struct
members unconditionally, which can lead to the following:

In order to set the rate range of a hw sunxi_ccu_probe calls
hw_to_ccu_common() assuming all entries in desc->ccu_clks are contained
in a ccu_common struct. This assumption is incorrect and, in
consequence, causes invalid pointer de-references.
Remove the faulty call. Instead, add one more loop that iterates over
the ccu_clks and sets the rate range, if required.

Fix UBSAN warnings that occur when using a system with 32 physical
cpu cores or more, or when the user defines a number of Ethernet
queues greater than or equal to FP_SB_MAX_E1x using the num_queues
module parameter.
Currently there is a read/write out of bounds that occurs on the array
"struct stats_query_entry query" present inside the "bnx2x_fw_stats_req"
struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h".
Looking at the definition of the "struct stats_query_entry query" array:
struct stats_query_entry query[FP_SB_MAX_E1x+
BNX2X_FIRST_QUEUE_QUERY_IDX];
FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts and
has a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3
meaning the array has a total size of 19.
Since accesses to "struct stats_query_entry query" are offset-ted by
BNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernet
queues should not exceed FP_SB_MAX_E1x (16). However one of these queues
is reserved for FCOE and thus the number of Ethernet queues should be set
to [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) if
it is not.
This is also described in a comment in the source code in
drivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definition
of FP_SB_MAX_E1x. Below is the part of this explanation that it important
for this patch
/*
* The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
* control by the number of fast-path status blocks supported by the
* device (HW/FW). Each fast-path status block (FP-SB) aka non-default
* status block represents an independent interrupts context that can
* serve a regular L2 networking queue. However special L2 queues such
* as the FCoE queue do not require a FP-SB and other components like
* the CNIC may consume FP-SB reducing the number of possible L2 queues
*
* If the maximum number of FP-SB available is X then:
* a. If CNIC is supported it consumes 1 FP-SB thus the max number of
* regular L2 queues is Y=X-1
* b. In MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
* c. If the FCoE L2 queue is supported the actual number of L2 queues
* is Y+1
* d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
* slow-path interrupts) or Y+2 if CNIC is supported (one additional
* FP interrupt context for the CNIC).
* e. The number of HW context (CID count) is always X or X+1 if FCoE
* L2 queue is supported. The cid for the FCoE L2 queue is always X.
*/
However this driver also supports NICs that use the E2 controller which can
handle more queues due to having more FP-SB represented by FP_SB_MAX_E2.
Looking at the commits when the E2 support was added, it was originally
using the E1x parameters: commit f2e0899f0f27 ("bnx2x: Add 57712 support").
Back then FP_SB_MAX_E2 was set to 16 the same as E1x. However the driver
was later updated to take full advantage of the E2 instead of having it be
limited to the capabilities of the E1x. But as far as we can tell, the
array "stats_query_entry query" was still limited to using the FP-SB
available to the E1x cards as part of an oversignt when the driver was
updated to take full advantage of the E2, and now with the driver being
aware of the greater queue size supported by E2 NICs, it causes the UBSAN
warnings seen in the stack traces below.
This patch increases the size of the "stats_query_entry query" array by
replacing FP_SB_MAX_E1x with FP_SB_MAX_E2 to be large enough to handle
both types of NICs.

When clearing registers on new write requests was added, the protection
for currently running commands was missed leading to concurrent access
to the testunit registers. Check the flag beforehand.

STOP fallsthrough to WRITE_REQUESTED but this became problematic when
clearing the testunit registers was added to the latter. Actually, there
is no reason to clear the testunit state after STOP. Doing it when a new
WRITE_REQUESTED arrives is enough. So, no need to fallthrough, at all.

This sets the default power save mode setting to enabled.
The power save feature is now stable and stress test issues, such as the
TX timeout error, have been resolved.
commit c7ee0bc8db32 ("Bluetooth: btnxpuart: Resolve TX timeout error in
power save stress test")
With this setting, the driver will send the vendor command to FW at
startup, to enable power save feature.
User can disable this feature using the following vendor command:
hcitool cmd 3f 23 03 00 00 (HCI_NXP_AUTO_SLEEP_MODE)

Commit 272970be3dab ("Bluetooth: hci_qca: Fix driver shutdown on closed
serdev") will cause below regression issue:
BT can't be enabled after below steps:
cold boot -> enable BT -> disable BT -> warm reboot -> BT enable failure
if property enable-gpios is not configured within DT|ACPI for QCA6390.
The commit is to fix a use-after-free issue within qca_serdev_shutdown()
by adding condition to avoid the serdev is flushed or wrote after closed
but also introduces this regression issue regarding above steps since the
VSC is not sent to reset controller during warm reboot.
Fixed by sending the VSC to reset controller within qca_serdev_shutdown()
once BT was ever enabled, and the use-after-free issue is also fixed by
this change since the serdev is still opened before it is flushed or wrote.
Verified by the reported machine Dell XPS 13 9310 laptop over below two
kernel commits:
commit e00fc2700a3f ("Bluetooth: btusb: Fix triggering coredump
implementation for QCA") of bluetooth-next tree.
commit b23d98d46d28 ("Bluetooth: btusb: Fix triggering coredump
implementation for QCA") of linus mainline tree.

Some Broadcom controllers found on Apple Silicon machines abuse the
reserved bits inside the PHY fields of LE Extended Advertising Report
events for additional flags. Add a quirk to drop these and correctly
extract the Primary/Secondary_PHY field.

"Reserved" for "Primary PHY" on a 4388 controller:
