[ Upstream commit 93a770b7e16772530196674ffc79bb13fa927dc6 ]
struct uart_port contains a cached copy of the Modem Control signals.
It is used to skip register writes in uart_update_mctrl() if the new
signal state equals the old signal state. It also avoids a register
read to obtain the current state of output signals.
When a uart_port is registered, uart_configure_port() changes signal
state but neglects to keep the cached copy in sync. That may cause
a subsequent register write to be incorrectly skipped. Fix it before
it trips somebody up.
This behavior has been present ever since the serial core was introduced
in 2002:
https://git.kernel.org/history/history/c/33c0d1b0c3eb
So far it was never an issue because the cached copy is initialized to 0
by kzalloc() and when uart_configure_port() is executed, at most DTR has
been set by uart_set_options() or sunsu_console_setup(). Therefore,
a stable designation seems unnecessary.

[ Upstream commit 08a0c6dff91c965e39905cf200d22db989203ccb ]
pl010_set_termios() briefly resets the CR register to zero.
Where does this register write come from?
The PL010 driver's IRQ handler ambauart_int() originally modified the CR
register without holding the port spinlock. ambauart_set_termios() also
modified that register. To prevent concurrent read-modify-writes by the
IRQ handler and to prevent transmission while changing baudrate,
ambauart_set_termios() had to disable interrupts. That is achieved by
writing zero to the CR register.
However in 2004 the PL010 driver was amended to acquire the port
spinlock in the IRQ handler, obviating the need to disable interrupts in
->set_termios():
https://git.kernel.org/history/history/c/157c0342e591
That rendered the CR register write obsolete. Drop it.

[ Upstream commit 14e2976fbabdacb01335d7f91eeebbc89c67ddb1 ]
The RPMh regulator driver is much newer and gets more attention, which in
consequence makes it do a few things better. Update qcom_smd-regulator's
probe function to mimic what rpmh-regulator does to address a couple of
issues:
- Probe defer now works correctly, before it used to, well,
kinda just die.. This fixes reliable probing on (at least) PM8994,
because Linux apparently cannot deal with supply map dependencies yet..
- Regulator data is now matched more sanely: regulator data is matched
against each individual regulator node name and throwing an -EINVAL if
data is missing, instead of just assuming everything is fine and
iterating over all subsequent array members.
- status = "disabled" will now work for disabling individual regulators in
DT. Previously it didn't seem to do much if anything at all.

[ Upstream commit 4e4f325a0a55907b14f579e6b1a38c53755e3de2 ]
The four RGMII interface modes take care of the required RGMII delay
configuration at the PHY and should not be limited by the network MAC
driver. Sadly, gemini was only permitting RGMII mode with no delays,
which would require the required delay to be inserted via PCB tracking
or by the MAC.
However, there are designs that require the PHY to add the delay, which
is impossible without Gemini permitting the other three PHY interface
modes. Fix the driver to allow these.

[ Upstream commit f22725c95ececb703c3f741e8f946d23705630b7 ]
Corentin Labbe reports that the SSI 1328 does not work when allowing
the PHY to operate at gigabit speeds, but does work with the generic
PHY driver.
This appears to be because m88e1118_config_init() writes a fixed value
to the MSCR register, claiming that this is to enable 1G speeds.
However, this always sets bits 4 and 5, enabling RGMII transmit and
receive delays. The suspicion is that the original board this was
added for required the delays to make 1G speeds work.
Add the necessary configuration for RGMII delays for the 88E1118 to
bring this into line with the requirements for RGMII support, and thus
make the SSI 1328 work.
Corentin Labbe has tested this on gemini-ssi1328 and gemini-ns2502.

[ Upstream commit d43e4271747ace01a27a49a97a397cb4219f6487 ]
Locally generated packets ingress the device through its CPU port. When
the CPU port is congested and there are not enough credits in its
headroom buffer, packets can be dropped.
While this might be acceptable for data packets that traverse the
network, configuration packets exchanged between the host and the device
(EMADs) should not be subjected to this flow control.
The "sdq_lp" bit in the SDQ (Send Descriptor Queue) context allows the
host to instruct the device to treat packets sent on this queue as
"local processing" and always process them, regardless of the state of
the CPU port's headroom.
Add the definition of this bit and set it for the dedicated SDQ reserved
for the transmission of EMAD packets. This makes the "local processing"
bit in the WQE (Work Queue Element) redundant, so clear it.

These calls will not be processed by FW anyway,
but error handling on sysfs level should be improved.
== Changes ==
This patch prohibits performing of all set commands

It offers better error handling as calls that are
not allowed will not be propagated further.
== Test ==
Writing to any sysfs file in passthrough mode will succeed.
Writing to any sysfs file in ONEVF mode will yield error:
"calling process does not have sufficient permission to execute a command".

ACPICA commit 3dd7e1f3996456ef81bfe14cba29860e8d42949e
According to ACPI 6.4, Section 16.2, the CPU cache flushing is
required on entering to S1, S2, and S3, but the ACPICA code
flushes the CPU cache regardless of the sleep state.
Blind cache flush on entering S5 causes problems for TDX.
Flushing happens with WBINVD that is not supported in the TDX
environment.
TDX only supports S5 and adjusting ACPICA code to conform to the
spec more strictly fixes the issue.

The reason for the crash is that the PCC channel index passed via region.address
in acpi_ex_store_object_to_node is interpreted as the channel subtype
incorrectly.
Assuming the PCC op_region support is not used by any other type, let us
remove the subtype check as the AML has no access to the subtype information.
Once we remove it, the kernel crash disappears and correctly complains about
missing PCC Opregion handler.

ACPICA commit d984f12041392fa4156b52e2f7e5c5e7bc38ad9e
If Operand[0] is a reference of the ACPI_REFCLASS_REFOF class,
acpi_ex_opcode_1A_0T_1R () calls acpi_ns_get_attached_object () to
obtain return_desc which may require additional resolution with
the help of acpi_ex_read_data_from_field (). If the latter fails,
the reference counter of the original return_desc is decremented
which is incorrect, because acpi_ns_get_attached_object () does not
increment the reference counter of the object returned by it.
This issue may lead to premature deletion of the attached object
while it is still attached and a use-after-free and crash in the
host OS. For example, this may happen when on evaluation of ref_of()
a local region field where there is no registered handler for the
given Operation Region.
Fix it by making acpi_ex_opcode_1A_0T_1R () return Status right away
after a acpi_ex_read_data_from_field () failure.

[ Upstream commit cdd156955f946beaa5f3a00d8ccf90e5a197becc ]
Some GPU heavy test programs manage to trigger the hangcheck quite often.
If there are no other GPU users in the system and the test program
exhibits a very regular structure in the commandstreams that are being
submitted, we can end up with two distinct submits managing to trigger
the hangcheck with the FE in a very similar address range. This leads
the hangcheck to believe that the GPU is stuck, while in reality the GPU
is already busy working on a different job. To avoid those spurious
GPU resets, also remember and consider the last completed fence seqno
in the hang check.

I found the bug using a custome USBFuzz port. It's a research work
to fuzz USB stack/drivers. I modified it to fuzz ath9k driver only,
providing hand-crafted usb descriptors to QEMU.
After fixing the value of pkt_tag to ATH_USB_RX_STREAM_MODE_TAG in QEMU
emulation, I found the KASAN report. The bug is triggerable whenever
pkt_len is above two MAX_RX_BUG_SIZE. I used the same input that crashes
to test the driver works when applying the patch.

USB 3.2 spec, 9.2.5.4 "Changing Function Suspend State" says that "If
the link is in a non-U0 state, then the device must transition the link
to U0 prior to sending the remote wake message", but the hub only
transits the link to U0 after signaling remote wakeup.
So be more forgiving and use a 20ms delay to let the link transit to U0
for remote wakeup.

[ Upstream commit 521223d8b3ec078f670c7c35a1a04b1b2af07966 ]
The min and max frequency QoS requests in the cpufreq core are
initialized to whatever the current min and max frequency values are
at the init time, but if any of these values change later (for
example, cpuinfo.max_freq is updated by the driver), these initial
request values will be limiting the CPU frequency unnecessarily
unless they are changed by user space via sysfs.
To address this, initialize min_freq_req and max_freq_req to
FREQ_QOS_MIN_DEFAULT_VALUE and FREQ_QOS_MAX_DEFAULT_VALUE,
respectively, so they don't really limit anything until user
space updates them.

[ Upstream commit d1579e61192e0e686faa4208500ef4c3b529b16c ]
Because refcount_dec_not_one() returns true if the target refcount
becomes saturated, it is generally unsafe to use its return value as
a loop termination condition, but that is what happens when a device
link's supplier device is released during runtime PM suspend
operations and on device link removal.
To address this, introduce pm_runtime_release_supplier() to be used
in the above cases which will check the supplier device's runtime
PM usage counter in addition to the refcount_dec_not_one() return
value, so the loop can be terminated in case the rpm_active refcount
value becomes invalid, and update the code in question to use it as
appropriate.
This change is not expected to have any visible functional impact.

[ Upstream commit 8c3e5b74b9e2146f564905e50ca716591c76d4f1 ]
The mmc core takes a specific path to support initializing of a
non-standard SDIO card. This is triggered by looking for the card-quirk,
MMC_QUIRK_NONSTD_SDIO.
In mmc_sdio_init_card() this gets rather messy, as it causes the code to
bail out earlier, compared to the usual path. This leads to that the OCR
doesn't get saved properly in card->ocr. Fortunately, only omap_hsmmc has
been using the MMC_QUIRK_NONSTD_SDIO and is dealing with the issue, by
assigning a hardcoded value (0x80) to card->ocr from an ->init_card() ops.
To make the behaviour consistent, let's instead rely on the core to save
the OCR in card->ocr during initialization.

[ Upstream commit 3af86b046933ba513d08399dba0d4d8b50d607d0 ]
In hexium_attach(dev, info), saa7146_vv_init() is called to allocate
a new memory for dev->vv_data. saa7146_vv_release() will be called on
failure of saa7146_register_device(). There is a dereference of
dev->vv_data in saa7146_vv_release(), which could lead to a NULL
pointer dereference on failure of saa7146_vv_init().
Fix this bug by adding a check of saa7146_vv_init().
This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.
Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.
Builds with CONFIG_VIDEO_HEXIUM_GEMINI=m show no new warnings,
and our static analyzer no longer warns about this code.

Since these two lockes are both initialized in ath11k_hal_srng_setup,
they are assigned with the same key. As a result lockdep suspects that
the task is trying to acquire the same lock (due to same key) while
already holding it, and thus reports the DEADLOCK warning. However as
they are different spinlock instances, the warning is false positive.
On the other hand, even no dead lock indeed, this is a major issue for
upstream regression testing as it disables lockdep functionality.
Fix it by assigning separate lock class key for each srng->lock.

[ Upstream commit 61a7904b6ace99b1bde0d0e867fa3097f5c8cee2 ]
The gpio-aspeed driver implements an irq_chip which need to be invoked
from hardirq context. Since spin_lock() can sleep with PREEMPT_RT, it is
no longer legal to invoke it while interrupts are disabled.
This also causes lockdep to complain about:
[ 0.649797] [ BUG: Invalid wait context ]
because aspeed_gpio.lock (spin_lock_t) is taken under irq_desc.lock
(raw_spinlock_t).
Let's use of raw_spinlock_t instead of spinlock_t.

[ Upstream commit f20f94f7f52c4685c81754f489ffcc72186e8bdb ]
The PHY settings table is supposed to be sorted by descending match
priority - in other words, earlier entries are preferred over later
entries.
The order of 1000baseKX/Full and 1000baseT/Full is such that we
prefer 1000baseKX/Full over 1000baseT/Full, but 1000baseKX/Full is
a lot rarer than 1000baseT/Full, and thus is much less likely to
be preferred.
This causes phylink problems - it means a fixed link specifying a
speed of 1G and full duplex gets an ethtool linkmode of 1000baseKX/Full
rather than 1000baseT/Full as would be expected - and since we offer
userspace a software emulation of a conventional copper PHY, we want
to offer copper modes in preference to anything else. However, we do
still want to allow the rarer modes as well.
Hence, let's reorder these two modes to prefer copper.

[ Upstream commit e8a91863eba3966a447d2daa1526082d52b5db2a ]
While running stress tests in roaming scenarios (switching ap's every 5
seconds, we discovered a issue which leads to tx hangings of exactly 5
seconds while or after scanning for new accesspoints. We found out that
this hanging is triggered by ath10k_mac_wait_tx_complete since the
empty_tx_wq was not wake when the num_tx_pending counter reaches zero.
To fix this, we simply move the wake_up call to htt_tx_dec_pending,
since this call was missed on several locations within the ath10k code.

[ Upstream commit ed05c7cf1286d7e31e7623bce55ff135723591bf ]
When enable debug config, it print below warning while shut down wlan
interface shuh as run "ifconfig wlan0 down".
The reason is because ar->regd_update_work is ran once, and it is will
call wiphy_lock(ar->hw->wiphy) in function ath11k_regd_update() which
is running in workqueue of ieee80211_local queued by ieee80211_queue_work().
Another thread from "ifconfig wlan0 down" will also accuqire the lock
by wiphy_lock(sdata->local->hw.wiphy) in function ieee80211_stop(), and
then it call ieee80211_stop_device() to flush_workqueue(local->workqueue),
this will wait the workqueue of ieee80211_local finished. Then deadlock
will happen easily if the two thread run meanwhile.
Below warning disappeared after this change.
