Pull rdma fixes from Doug Ledford:
- Various driver bug fixes in mlx5, mlx4, bnxt_re and qedr, ranging
from bugs under load to bad error case handling
- There in one largish patch fixing the locking in bnxt_re to avoid a
machine hard lock situation
- A few core bugs on error paths
- A patch to reduce stack usage in the new CQ API
- One mlx5 regression introduced in this merge window
- There were new syzkaller scripts written for the RDMA subsystem and
we are fixing issues found by the bot
- One of the commits (aa0de36a40f4 “RDMA/mlx5: Fix integer overflow
while resizing CQ”) is missing part of the commit log message and one
of the SOB lines. The original patch was from Leon Romanovsky, and a
cut-n-paste separator in the commit message confused patchworks which
then put the end of message separator in the wrong place in the
downloaded patch, and I didn’t notice in time. The patch made it into
the official branch, and the only way to fix it in-place was to
rebase. Given the pain that a rebase causes, and the fact that the
patch has relevant tags for stable and syzkaller, a revert of the
munged patch and a reapplication of the original patch with the log
message intact was done.

The original commit of this patch has a munged log message that is
missing several of the tags the original author intended to be on the
patch. This was due to patchworks misinterpreting a cut-n-paste
separator line as an end of message line and munging the mbox that was
used to import the patch:
https://patchwork.kernel.org/patch/10264089/
The original patch will be reapplied with a fixed commit message so the
proper tags are applied.

When the DELL_SMBIOS_SMM backend is enabled, the DELL_SMBIOS symbol
depends on DELL_DCDBAS, and we must avoid the situation where
DELL_SMBIOS=y and DCDBAS=m.
Adding the conditional dependency to DELL_SMBIOS such as:
depends !DELL_SMBIOS_SMM || (DCDBAS || DCDBAS=n)
results in the Kconfig tooling complaining about a circular dependency,
although it appears to work in practice.
Avoid the errors by simplifying the dependency and forcing DELL_SMBIOS
to be <= DCDBAS if DCDBAS is enabled (thanks to Greg KH for the
suggestion).

Avoid accidental configurations by setting default y for DELL_SMBIOS
backends. Avoid this impacting the default build size, by making them
dependent on DELL_SMBIOS, so they only appear when DELL_SMBIOS is
manually selected, or by DELL_LAPTOP or DELL_WMI.
While DELL_SMBIOS does have a prompt, it does not have any dependencies.
Keeping DELL_SMBIOS visible, despite being "select"ed by DELL_LAPTOP and
DELL_WMI, is a deliberate choice to provide context for the WMI and SMM
backends, which would otherwise appear to float without context within
the menu.

Some race conditions were raised due to dell-smbios and its backends
not being ready by the time that a consumer would call one of the
exported methods.
To avoid this problem, guarantee that all initialization has been
done by linking them all together and running init for them all.
As part of this change the Kconfig needs to be adjusted so that
CONFIG_DELL_SMBIOS_SMM and CONFIG_DELL_SMBIOS_WMI are boolean
rather than modules.
CONFIG_DELL_SMBIOS is a visually selectable option again and both
CONFIG_DELL_SMBIOS_WMI and CONFIG_DELL_SMBIOS_SMM are optional.

This reverts commit 48282969826b3d3c76e908182f69724d86d995fe which
caused the following issues:
1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working
after suspend-resume cycle. Due to strange state of the device another
suspend is impossible.
The following dmesg errors can be observed:
thinkpad_acpi: EC reports that Thermal Table has changed
rmi4_smbus 7-002c: failed to get SMBus version number!
rmi4_physical rmi4-00: rmi_driver_reset_handler: Failed to read current IRQ mask.

rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts!
psmouse: probe of serio3 failed with error -1
2. On another T460p with BIOS version 2.15 two finger scrolling gesture
on the touchpad stops working after suspend-resume cycle (about 75%
reproducibility, when it still works, the scrolling gesture becomes
laggy). Nothing suspicious appears in the dmesg.
Analysis form Richard Schütz:
"RMI is unreliable on the ThinkPad T460p because the device is affected
by the firmware behavior addressed in a7ae81952cda ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")."
The affected devices often show:
i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers
i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited

During switch from vga->extended, if we set the VGA_TEST_ENABLE and then

Then vBIOS will have it poll for the VGA_TEST_RENDER_DONE and unset

Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK
If graphics plane go from 1 pipe to hsplit, the cursor updates
after mpc programming and unlock. Which means there is a window
of time where cursor is enabled on the wrong pipe if it's on
the right side of the screen (i.e. case where cursor need to
move from pipe 0 to pipe 3 post split). This will cause pstate hang.
Solution is to program the cursor while still locked.

Because AMDGPU_CRTC_IRQ_VLINE1 = 6, it expected 6 more crtcs to be
programed with disabled irq state in amdgpu_irq_disable_all. That caused errors and accessed
the wrong memory location.

There is no need to call drm_mode_set_crtcinfo() again once
crtc timing is decided. Otherwise non-native/unsupported timing
might get overwritten.

There's no good place in DC to cover all place where stream signal should
be updated. update_stream_signal depends on timing which comes from DM.

We've got a helper function to call dc_create_stream_for_sink and one
other place that calls it directly. Make sure we call the helper
functions always since we need to update a bunch of things in stream and
don't want to miss that.

The below commit
"drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"
introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.
This change leads to BUG hit while performing atomic commit on amd driver.
As a fix this patch ensures that we disable the CRTC's with NULL FB by returning
-EINVAL and hence triggering fall back to the old behavior and turning off the
crtc in atomic_remove_fb().
V2: Added error check for plane_state and removed sanity check for crtc.

There have been many reports of Ellesmere and Baffin systems not being
able to drive HDMI 4k60 due to the fact that we check the HDMI_6GB_EN
bit from VBIOS table. Windows seems to not have this issue.
On some systems we fail to the encoder cap info from VBIOS. In that case
we should default to enabling HDMI6G support.
