If the VBT assigned tc->legacy_port mismatches the live_status indicator
for the connector, we ignore the VBT directive and switch over to the HW
setting. This is not a driver error, unless we happen to misparse the
VBT or the live_status registers. However, for the system in CI where
the error is only reported on 1 port out of 4, the evidence indicates
the VBT is wrong. Stop flaging this as an error since the cause is
beyond our control, fixup the mistake and continue on.

The newly introduced kvm_msr_ignored_check() tries to print error or
debug messages via vcpu_*() macros, but those may cause Oops when NULL
vcpu is passed for KVM_GET_MSRS ioctl.
Fix it by replacing the print calls with kvm_*() macros.
(Note that this will leave vcpu argument completely unused in the
function, but I didn't touch it to make the fix as small as
possible. A clean up may be applied later.)

I initially thought raw_cpu_read() was OK, since if it is !0 we have
IRQs disabled and can't get migrated, so if we get migrated both CPUs
must have 0 and it doesn't matter which 0 we read.
And while that is true; it isn't the whole store, on pretty much all
architectures (except x86) this can result in computing the address for
one CPU, getting migrated, the old CPU continuing execution with another
task (possibly setting recursion) and then the new CPU reading the value
of the old CPU, which is no longer 0.
Similer to:

On a system without uniform support for AArch32 at EL0, it is possible
for the guest to force run AArch32 at EL0 and potentially cause an
illegal exception if running on a core without AArch32. Add an extra
check so that if we catch the guest doing that, then we prevent it from
running again by resetting vcpu->arch.target and return
ARM_EXCEPTION_IL.
We try to catch this misbehaviour as early as possible and not rely on
an illegal exception occuring to signal the problem. Attempting to run a
32bit app in the guest will produce an error from QEMU if the guest
exits while running in AArch32 EL0.
Tested on Juno by instrumenting the host to fake asym aarch32 and
instrumenting KVM to make the asymmetry visible to the guest.

Mark flush request as IDLE in its .end_io(), aligning it with how normal
requests behave. The flush request stays in in-flight tags if we're not
using an IO scheduler, so we need to change its state into IDLE.
Otherwise, we will hang in blk_mq_tagset_wait_completed_request() during
error recovery because flush the request state is kept as COMPLETED.

ibx_irq_pre_postinstall() looks totally pointless. We can just
init both SDEIMR and SDEIER at the same time before enabling the
master interrupt. It's equally racy as the other order due
to doing all of this from the postinstall stage with the interrupt
handler already in place. That is, safe with MSI but racy with
shared legacy interrupts. Fortunately we should have MSI on all ilk+.

No reason that I can see why we should enable the hpd detection logic

well. Let's just eliminate the redundant early setup.

Just like with the DDIs tgl+ renamed the AUX CHs to reflect
the type of the DDI. Let's add the aliasing enum values for
the type-C AUX CHs.

Let's pimp the DDI encoder->name to reflect what the spec calls them.
Ie. on pre-tgl DDI A-F, on tgl+ DDI A-C or DDI TC1-6.
Also since each encoder is really a combination of the DDI and the PHY
we include the PHY name as well.
ICL is a bit special since it already has the two different types
of DDIs (combo or TC) but it still calls them just DDI A-F regarless
of the type. For that let's add an extra "(TC)" note to remind
is which type of DDI it really is.
The code is darn ugly, but not sure there's much we can do about it.

Since tgl the DDIs have been named A,B,C,TC1,TC2,TC3...
Add the appropriate enum values for the TC DDIs to enum port.

interconnect fixes for v5.10
This contains one core fix and a few driver fixes.
- Fix the core to perform also aggregation when setting the initial
bandwidth with sync_state.
- Fixes in some drivers to make sure the correct sequence is used for
initialization when we use sync_state.
- Fix in the sdm845 driver to prevent a board hang that was hit when
bandwidth scaling for display and multimedia was enabled.

The ABI files are supposed to be unique. Yet,
in the specific case of hw_pattern, there are some duplicated
entries as warned by scripts/get_abi.pl:
Warning: /sys/class/leds/<led>/hw_pattern is defined 3 times: Documentation/ABI/testing/sysfs-class-led-trigger-pattern:14 Documentation/ABI/testing/sysfs-class-led-driver-sc27xx:0 Documentation/ABI/testing/sysfs-class-led-driver-el15203000:0
Drop the duplication from the ABI files, moving the specific
definitions to files inside Documentation/leds.

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.
