Pull char/misc fixes/removals from Greg KH:
 "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"

Pull driver core and documentation fixes from Greg KH:
 "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 wih 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"

bb2bd7c7f3 dt-bindings: irqchip: ti, sci-inta: Update for unmapped event handling
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.

bd6e8441c2 docs: ABI: sysfs-class-backlight: unify ABI documentation
Both adp8860 and adp8870 define some extensions to the
backlight class. This causes warnings:

	Warning: /sys/class/backlight/<backlight>/ambient_light_level is defined 2 times:  /sys/class/backlight/<backlight>/ambient_light_level:8  /sys/class/backlight/<backlight>/ambient_light_level:30
	Warning: /sys/class/backlight/<backlight>/ambient_light_zone is defined 2 times:  /sys/class/backlight/<backlight>/ambient_light_zone:18  /sys/class/backlight/<backlight>/ambient_light_zone:40

As ABI definitions shouldn't be duplicated.

Unfortunately, the ABI is dependent on the specific device
features. As such, ambient_light_level range is somewhat
different among the supported devices.

The ambient_light_zone is even worse: the meanings of each
preset are different, and there's no ABI to retrieve
the supported types nor their meanins. Unfortunately,
it is too late to fix it without causing regressions,
as this has been used since Kernel v2.6.35.

Rewrite those ABI documentation using the current documentation
as a reference, and double-checking at the datasheets:

	https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8870.pdf
	https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8860.pdf

in order to properly document the differences between those two
drivers.

96d389ca10 arm64: Add workaround for Arm Cortex-A77 erratum 1508412
On Cortex-A77 r0p0 and r1p0, a sequence of a non-cacheable or device load
and a store exclusive or PAR_EL1 read can cause a deadlock.

The workaround requires a DMB SY before and after a PAR_EL1 register
read. In addition, it's possible an interrupt (doing a device read) or
KVM guest exit could be taken between the DMB and PAR read, so we
also need a DMB before returning from interrupt and before returning to
a guest.

A deadlock is still possible with the workaround as KVM guests must also
have the workaround. IOW, a malicious guest can deadlock an affected
systems.

This workaround also depends on a firmware counterpart to enable the h/w
to insert DMB SY after load and store exclusive instructions. See the
errata document SDEN-1152370 v10 [1] for more information.

ef5dd6a0c8 arm64: mte: Document that user PSTATE.TCO is ignored by kernel uaccess
On exception entry, the kernel explicitly resets the PSTATE.TCO (tag
check override) so that any kernel memory accesses will be checked (the
bit is restored on exception return). This has the side-effect that the
uaccess routines will not honour the PSTATE.TCO that may have been set
by the user prior to a syscall.

There is no issue in practice since PSTATE.TCO is expected to be used
only for brief periods in specific routines (e.g. garbage collection).
To control the tag checking mode of the uaccess routines, the user will
have to invoke a corresponding prctl() call.

Document the kernel behaviour w.r.t. PSTATE.TCO accordingly.

Those files only contain

markups, but they're included twice there: one to parse
such markup, and another one to parse internal functions.

In the case of amdgpu_xgmi.c, as it has just one such
markup, we can simply include the file once, and let it
parse the entire file without passing arguments to kernel-doc.

This should place everything altogether.

For amdgpu_ras.c, however, we need to remove the kernel-doc
with just internal. This should be re-introduced if this
file ever gets new non-DOC markups.

4b7560c5e4 ice: docs fix a devlink info that broke a table
Changeset 410d06879c ("ice: add the DDP Track ID to devlink info")
added description for a new devlink field, but forgot to add
one of its columns, causing it to break:

	.../Documentation/networking/devlink/ice.rst:15: WARNING: Error parsing content block for the "list-table" directive: uniform two-level bullet list expected, but row 11 does not contain the same number of items as row 1 (3 vs 4).

	.. list-table:: devlink info versions implemented
	    :widths: 5 5 5 90
...
	    * - ``fw.app.bundle_id``
	      - 0xc0000001
	      - Unique identifier for the DDP package loaded in the device. Also
	        referred to as the DDP Track ID. Can be used to uniquely identify
	        the specific DDP package.

Add the type field to the ``fw.app.bundle_id`` row.

97e44c4f0c docs: net: statistics.rst: remove a duplicated kernel-doc
include/linux/ethtool.h is included twice with kernel-doc,
both to document ethtool_pause_stats(). The first one is
at statistics.rst, and the second one at ethtool-netlink.rst.

Replace one of the references to use the name of the
function. The automarkup.py extension should create the
cross-references.

Solves this warning:

	../Documentation/networking/ethtool-netlink.rst: WARNING: Duplicate C declaration, also defined in 'networking/statistics'.
	Declaration is 'ethtool_pause_stats'.
