Pull x86 fixes from Thomas Gleixner:
"A small set of fixes for x86:
- Cure the fallout from the MSI irqdomain overhaul which missed that
the Intel IOMMU does not register virtual function devices and
therefore never reaches the point where the MSI interrupt domain is
assigned. This made the VF devices use the non-remapped MSI domain
which is trapped by the IOMMU/remap unit
- Remove an extra space in the SGI_UV architecture type procfs output
for UV5
- Remove a unused function which was missed when removing the UV BAU
TLB shootdown handler"

There might be some requests pending in the buffer when the interface close
sequence occurs. In some devices, these pending requests might lead to the
module not shutting down properly when m_can_clk_stop() is called.
Therefore, move the device to init state before potentially powering it down.

m_can_handle_state_change() is called with the new_state as an argument.
In the switch statements for CAN_STATE_ERROR_ACTIVE, the comment and the

regmap is a library function that gets selected by drivers that need it. No
driver modules should depend on it. Instead depends on SPI and select
REGMAP_SPI. Depending on REGMAP_SPI makes this driver only build if another
driver already selected REGMAP_SPI, as the symbol can't be selected through the
menu kernel configuration.

pm_runtime_get_sync() will increment pm usage at first and it will resume the
device later. If runtime of the device has error or device is in inaccessible
state(or other error state), resume operation will fail. If we do not call put
operation to decrease the reference, it will result in reference leak in the
two functions flexcan_get_berr_counter() and flexcan_open().
Moreover, this device cannot enter the idle state and always stay busy or other
non-idle state later. So we should fix it through adding
pm_runtime_put_noidle().

In the patch
d9b081e3fc4b ("can: flexcan: remove ack_grp and ack_bit handling from driver")
the unused ack_grp and ack_bit were removed from the driver. However in the
comment, the "req_bit" was accidentally removed, too.
This patch adds back the "req_bit" bit.

The left shift of int 32 bit integer constant 1 is evaluated using 32 bit
arithmetic and then assigned to a signed 64 bit variable. In the case where
time_ref->adapter->ts_used_bits is 32 or more this can lead to an oveflow.
Avoid this by shifting using the BIT_ULL macro instead.

On arm imx6, when opening the chip's netdev, the whole Linux
kernel intermittently hangs/freezes.
This is caused by a bug in the driver code which tests if pcie
interrupts are working correctly, using the software interrupt:
1. open: enable the software interrupt
2. open: tell the chip to assert the software interrupt
3. open: wait for flag
4. ISR: acknowledge s/w interrupt, set flag
5. open: notice flag, disable the s/w interrupt, continue
Unfortunately the ISR only acknowledges the s/w interrupt, but
does not disable it. This will re-trigger the ISR in a tight
loop.
On some (lucky) platforms, open proceeds to disable the s/w
interrupt even while the ISR is 'spinning'. On arm imx6,
the spinning ISR does not allow open to proceed, resulting
in a hung Linux kernel.
Fix minimally by disabling the s/w interrupt in the ISR, which
will prevent it from spinning. This won't break anything because
the s/w interrupt is used as a one-shot interrupt.
Note that this is a minimal fix, overlooking many possible
cleanups, e.g.:
- lan743x_intr_software_isr() is completely redundant and reads
INT_STS twice for no apparent reason
- disabling the s/w interrupt in lan743x_intr_test_isr() is now
redundant, but harmless
- waiting on software_isr_flag can be converted from a sleeping
poll loop to wait_event_timeout()

As soon as you add the second port to a VLAN, all other port
membership configuration is overwritten with zeroes. The HW interprets
this as all ports being "unmodified members" of the VLAN.
In the simple case when all ports belong to the same VLAN, switching
will still work. But using multiple VLANs or trying to set multiple
ports as tagged members will not work.
On the 6352, doing a VTU GetNext op, followed by an STU GetNext op
will leave you with both the member- and state- data in the VTU/STU
data registers. But on the 6097 (which uses the same implementation),
the STU GetNext will override the information gathered from the VTU
GetNext.
Separate the two stages, parsing the result of the VTU GetNext before
doing the STU GetNext.
We opt to update the existing implementation for all applicable chips,
as opposed to creating a separate callback for 6097, because although
the previous implementation did work for (at least) 6352, the
datasheet does not mention the masking behavior.

Some 360 degree hinges (yoga) style 2-in-1 devices use 2 KXCJ91008-s
to allow the OS to determine the angle between the display and the base
of the device, so that the OS can determine if the 2-in-1 is in laptop
or in tablet-mode.
On Windows both accelerometers are read by a special HingeAngleService
process; and this process calls a DSM (Device Specific Method) on the
ACPI KIOX010A device node for the sensor in the display, to let the
embedded-controller (EC) know about the mode so that it can disable the
kbd and touchpad to avoid spurious input while folded into tablet-mode.
This notifying of the EC is problematic because sometimes the EC comes up
thinking that device is in tablet-mode and the kbd and touchpad do not
work. This happens for example on Irbis NB111 devices after a suspend /
resume cycle (after a complete battery drain / hard reset without having
booted Windows at least once). Other 2-in-1s which are likely affected
too are e.g. the Teclast F5 and F6 series.
The kxcjk-1013 driver may seem like a strange place to deal with this,
but since it is *the* driver for the ACPI KIOX010A device, it is also
the driver which has access to the ACPI handle needed by the DSM.
Add support for calling the DSM and on probe unconditionally tell the

Replace the boolean is_smo8500_device variable with an acpi_type enum.
For now this can be either ACPI_GENERIC or ACPI_SMO8500, this is a
preparation patch for adding special handling for the KIOX010A ACPI HID,
which will add a ACPI_KIOX010A acpi_type to the introduced enum.
For stable as needed as precursor for next patch.

The NULL pointer being dereferenced is mode.
Git bisect has identified the following commit as bad:
f28e32d3906e drm/nouveau/kms: Don't change EDID when it hasn't actually changed
Here is the chain of events that causes the oops.
On entry to nouveau_connector_detect_lvds, edid is set to NULL. The call
to nouveau_connector_detect sets nv_connector->edid to valid memory,
with status set to connector_status_connected and the flow of execution
branching to the out label.
The subsequent call to nouveau_connector_set_edid erronously clears
nv_connector->edid, via the local edid pointer which remains set to NULL.
Fix this by setting edid to the value of the just acquired
nv_connector->edid and executing the body of nouveau_connector_set_edid
only if nv_connector->edid and edid point to different memory addresses
thus preventing nv_connector->edid from being turned into a dangling
pointer.

Currently, we may set the tunnel option flag when the size of metadata
is zero. For example, we set TUNNEL_GENEVE_OPT in the receive function
no matter the geneve option is present or not. As this may result in
issues on the tunnel flags consumers, this patch fixes the issue.

Depending on the SoC/platform the CPSW can completely lose context after a
suspend/resume cycle, including CPSW wrapper (WR) which will cause reset of
WR_C0_MISC_EN register, so CPTS IRQ will became disabled.
Fix it by moving CPTS IRQ enabling in cpsw_ndo_open() where CPTS is
actually started.

The original patch for commit 3d2e7aec7013 ("drm/tegra: output: Don't
leak OF node on error") contained this hunk, but it was accidentally
dropped during conflict resolution. This causes use-after-free errors
on devices that use an I2C controller for HDMI DDC/CI on Tegra210 and
later.

Pull pin control fixes from Linus Walleij:
"A bunch of pin control fixes for the v5.10 kernel series.
Nothing in particular to say about it, because they are all driver
fixes.
I'm happy that some AMD driver fixes are appearing, it's been an
undermaintained driver, and laptops have suffered.
Summary:
- Two fixes to the Intel pin controller drivers: fixing pull
resistance bias.
- Fix some invalid SSI pins on the Ingenic pin controller.
- Make sure the clock is enabled when requesting interrupts from the
Rockchip GPIO controller.
- Make sure IRQs are mapped when looking up the IRQ for a GPIO line
on the Rockchip GPIO Write.
- Two regmap initialization fixes for the MCP23s08.
- Fix a GPI-only prefix function problem on the Aspeed pin
controller.
- Disable the debounce filter correctly on the AMD pin controller.
- Correct the timer clock setting for the AMD debounce timer.
- Make the Qualcomm pin controller more cautious around the handling
of PDC-related GPIO interrupts.
- Fix the interrupt map in the Qualcomm SM8250 pin controller"
