The API documentation states that general error codes are not detailed, but
errors with specific meanings are. On arm64, KVM_RUN can return error
numbers with a different meaning than what is described by POSIX or the C99
standard (as taken from man 3 errno).
Absent from the newly documented error codes is ERANGE which can be
returned when making a change to the EL2 stage 1 tables if the address is
larger than the largest supported input address. Assuming no bugs in the
implementation, that is not possible because the input addresses which are
mapped are the result of applying the macro kern_hyp_va() on kernel virtual
addresses.

Add an early parameter that allows users to select the mode of operation
for KVM/arm64.
For now, the only supported value is "protected". By passing this flag
users opt into the hypervisor placing additional restrictions on the
host kernel. These allow the hypervisor to spawn guests whose state is
kept private from the host. Restrictions will include stage-2 address
translation to prevent host from accessing guest memory, filtering its
SMC calls, etc.
Without this parameter, the default behaviour remains selecting VHE/nVHE
based on hardware support and CONFIG_ARM64_VHE.

Since commit:
0e030a373d ("can: flexcan: fix endianess detection")
the fsl,imx53-flexcan isn't compatible with the fsl,p1010-flexcan any more. As
the former accesses the IP core in Little Endian mode and the latter uses Big
Endian mode.
With the conversion of the flexcan DT bindings to yaml, the dt_binding_check
this throws the following error:
Documentation/devicetree/bindings/clock/imx5-clock.example.dt.yaml: can@53fc8000: compatible: 'oneOf' conditional failed, one must be fixed:
['fsl,imx53-flexcan', 'fsl,p1010-flexcan'] is too long
Additional items are not allowed ('fsl,p1010-flexcan' was unexpected)
'fsl,imx53-flexcan' is not one of ['fsl,imx7d-flexcan', 'fsl,imx6ul-flexcan', 'fsl,imx6sx-flexcan']
'fsl,imx53-flexcan' is not one of ['fsl,ls1028ar1-flexcan']
'fsl,imx6q-flexcan' was expected
'fsl,lx2160ar1-flexcan' was expected
From schema: /builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/net/can/fsl,flexcan.yaml
The error is fixed by replacing the "fsl,p1010-flexcan" compatible
(which turned out the be incompatible) with "fsl,imx25-flexcan" in the
binding example.

As both the i.MX35 and i.MX53 flexcan IP cores are compatible to the i.MX25,
they are listed as:

Here's some small fixes for 5.10-rc2 and a big driver removal.
The fixes are for some reported issues in the interconnect and coresight
drivers, nothing major.
The "big" driver removal is the MIC drivers have been asked to be
removed as the hardware never shipped and Intel no longer wants to
maintain something that no one can use. This is welcomed by many as the
DMA usage of these drivers was "interesting" and the security people
were starting to question some issues that were starting to be found in
the codebase.
Note, one of the subsystems for this driver, the "VOP" code, will
probably come back in future kernel versions as it was looking to
potentially solve some PCIe virtualization issues that a number of other
vendors were wanting to solve. But as-is, this codebase didn't work for
anyone else so no actual functionality is being removed.
All of these have been in linux-next with no reported issues.

"Here's some small fixes for 5.10-rc2 and a big driver removal.
The fixes are for some reported issues in the interconnect and
coresight drivers, nothing major.
The "big" driver removal is the MIC drivers have been asked to be
removed as the hardware never shipped and Intel no longer wants to
maintain something that no one can use. This is welcomed by many as
the DMA usage of these drivers was "interesting" and the security
people were starting to question some issues that were starting to be
found in the codebase.
Note, one of the subsystems for this driver, the "VOP" code, will
probably come back in future kernel versions as it was looking to
potentially solve some PCIe virtualization issues that a number of
other vendors were wanting to solve. But as-is, this codebase didn't
work for anyone else so no actual functionality is being removed.
All of these have been in linux-next with no reported issues"

Here is one tiny debugfs change to fix up an API where the last user was
successfully fixed up in 5.10-rc1 (so it couldn't be merged earlier),
and a much larger Documentation/ABI/ update to the files so they can be
automatically parsed by our tools.
The Documentation/ABI/ updates are just formatting issues, small ones to
bring the files into parsable format, and have been acked by numerous
subsystem maintainers and the documentation maintainer. I figured it
was good to get this into 5.10-rc2 to help with the merge issues that
would arise if these were to stick in linux-next until 5.11-rc1.
The debugfs change has been in linux-next for a long time, and the
Documentation updates only for the last linux-next release.

The new DMA architecture introduced with AM64 introduced new event types:
unampped events.
These events are mapped within INTA in contrast to other K3 devices where
the events with similar function was originating from the UDMAP or ringacc.
The ti,unmapped-event-sources should contain phandle array to the devices
in the system (typically DMA controllers) from where the unmapped events
originate.
