8238b45798 wait_on_bit: add an acquire memory barrier
There are several places in the kernel where wait_on_bit is not followed
by a memory barrier (for example, in drivers/md/dm-bufio.c:new_read).

On architectures with weak memory ordering, it may happen that memory
accesses that follow wait_on_bit are reordered before wait_on_bit and
they may return invalid data.

Fix this class of bugs by introducing a new function "test_bit_acquire"
that works like test_bit, but has acquire memory ordering semantics.

25bcc828d2 drm/i915/dg2: Incorporate Wa_16014892111 into DRAW_WATERMARK tuning
Although register tuning settings are generally implemented via the
workaround infrastructure, it turns out that the DRAW_WATERMARK register
is not properly saved/restored by hardware around power events (i.e.,
RC6 entry) so updates to the value cannot be applied in the usual
manner.  New workaround Wa_16014892111 informs us that any tuning
updates to this register must instead be applied via an INDIRECT_CTX
batch buffer.  This will ensure that the necessary value is re-applied
when a context begins running, even if an RC6 entry had wiped the
register back to hardware defaults since the last context ran.

2b96f92ca4 PCI/MSI: Correct 'can_mask' test in msi_add_msi_desc()
71020a3c0d ("PCI/MSI: Use msi_add_msi_desc()") inadvertently reversed
the sense of "msi_attrib.can_mask" in one use:

  - if (entry->pci.msi_attrib.can_mask) {
  -         addr = pci_msix_desc_addr(entry);
  -         entry->pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);
  + if (!desc.pci.msi_attrib.can_mask) {
  +         addr = pci_msix_desc_addr(&desc);
  +         desc.pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);

Restore the original test.

a92438c5a3 soc: mediatek: mtk-svs: Use bitfield access macros where possible
In order to enhance readability and safety during registers setup
and value retrieval, redefine a few register related macros and
convert all open-coded instances of bitfield setting/retrieval
to use the FIELD_PREP() and FIELD_GET() macros.
While at it, some macros were renamed to further enhance readability.

707527956d /dev/null: add IORING_OP_URING_CMD support
This patch adds support for the io_uring command pass through, aka
IORING_OP_URING_CMD, to the /dev/null driver.  As with all of the
/dev/null functionality, the implementation is just a simple sink
where commands go to die, but it should be useful for developers who
need a simple IORING_OP_URING_CMD test device that doesn't require
any special hardware.

command.  This includes the addition of a new permission in the
existing "io_uring" object class: "cmd".  The subject of the new
permission check is the domain of the process requesting access, the
object is the open file which points to the device/file that is the
target of the IORING_OP_URING_CMD operation.  A sample policy rule
is shown below:

io-uring cmd support was added through ee692a21e9 ("fs,io_uring:

file_operations to allow a new command which each subsystem can use
to enable command passthrough. Add an LSM specific for the command
passthrough which enables LSMs to inspect the command details.

This was discussed long ago without no clear pointer for something
conclusive, so this enables LSMs to at least reject this new file
operation.

378e0f9f0b drm: bridge: icn6211: Add support for external REFCLK
The ICN6211 is capable of deriving its internal PLL clock from either
MIPI DSI HS clock, external REFCLK clock, or even internal oscillator.
Currently supported is only the first option. Add support for external
REFCLK clock input in addition to that.

There is little difference between these options, except that in case
of MIPI DSI HS clock input, the HS clock are pre-divided by a fixed /4
divider before being fed to the PLL input, while in case of external
REFCLK, the RECLK clock are fed directly into the PLL input.

Per exceptionally poor documentation, the REFCLK must be in range of
10..154 MHz.

4d054ca9ad drm: bridge: icn6211: Add and use hs_rate and lp_rate
Fill in hs_rate and lp_rate to struct mipi_dsi_device for this bridge and
adjust DSI input frequency calculations such that they expect the DSI host
to configure HS clock according to hs_rate.

This is an optimization for the DSI burst mode case. In case the DSI device
supports DSI burst mode, it is recommended to operate the DSI interface at
the highest possible HS clock frequency which the DSI device supports. This
permits the DSI host to send as short as possible bursts of data on the DSI
link and keep the DSI data lanes in LP mode otherwise, which reduces power
consumption.

fa3fbe6403 wifi: mt76: mt7921e: fix crash in chip reset fail
In case of drv own fail in reset, we may need to run mac_reset several
times. The sequence would trigger system crash as the log below.

Because we do not re-enable/schedule "tx_napi" before disable it again,
the process would keep waiting for state change in napi_diable(). To
avoid the problem and keep status synchronize for each run, goto final
resource handling if drv own failed.

83ac7a1c2e platform/x86: msi-laptop: Fix old-ec check for backlight registering
Commit 2cc6c71779 ("msi-laptop: Port to new backlight interface
selection API") replaced this check:

	if (!quirks->old_ec_model || acpi_video_backlight_support())
		pr_info("Brightness ignored, ...");
	else
		do_register();

With:

	if (quirks->old_ec_model ||
	    acpi_video_get_backlight_type() == acpi_backlight_vendor)
		do_register();

But since the do_register() part was part of the else branch, the entire
condition should be inverted.  So not only the 2 statements on either
side of the || should be inverted, but the || itself should be replaced
with a &&.

In practice this has likely not been an issue because the new-ec models
(old_ec_model==false) likely all support ACPI video backlight control,
making acpi_video_get_backlight_type() return acpi_backlight_video
turning the second part of the || also false when old_ec_model == false.

It was observed that on a Thinkpad T14 Gen1 (AMD) that the platform
profile is starting up in 'low-power' mode after refreshing what the
firmware had.  This is most likely a firmware bug, but as a harmless
workaround set the default profile to 'balanced' at thinkpad_acpi startup.
