The state checker overwrites the old crtc state with the
current hardware state. While that does save a kmalloc() it seems
rather dubious as there might still be something that we need
in the old crtc state.
Stop doing that and just allocate a temporary state for the state
checker. Should the extra malloc during the commit phase turn out
too annoying we could of course preallocate one for each crtc, but
let's proceed with the straightforward approch for now.
And while at it let's mark the new crtc state as const to make
sure the state checker doesn't mess it up.

The DSU PMU allows monitoring performance events in the DSU cluster,
which is done by configuring and reading back values from the DSU PMU
system registers. However, for write-access to be allowed by ELs lower
than EL3, the EL3 firmware needs to update the setting on the ACTLR3_EL3
register, as it is disallowed by default.
That configuration is not done on the firmware used by the MT8195 SoC,
as a consequence, booting a MT8195-based machine like
mt8195-cherry-tomato-r2 with CONFIG_ARM_DSU_PMU enabled hangs the kernel
just as it writes to the CLUSTERPMOVSCLR_EL1 register, since the
instruction faults to EL3, and BL31 apparently just re-runs the
instruction over and over.
Mark the DSU PMU node in the Devicetree with status "fail", as the
machine doesn't have a suitable firmware to make use of it from the
kernel, and allowing its driver to probe would hang the kernel.

I am a top reviewer mainly for MediaTek SoC related patches in most

and new drivers and devicetrees when required.
The MediaTek scene saw a generous increase in number of patches that
are sent to the lists every week, increasing the amount of required
efforts to maintain the MTK bits overall, and we will possibly see
even more of that.
For this reason, and also because of suggestions and encouragement

commit c35559f94e ("x86/shstk: Introduce map_shadow_stack syscall")
recently added support for map_shadow_stack() but it is limited to x86
only for now. There is a possibility that other architectures (namely,
arm64 and RISC-V), that are implementing equivalent support for shadow
stacks, might need to add support for it.
Independent of that, reserving arch-specific syscall numbers in the
syscall tables of all architectures is good practice and would help
avoid future conflicts. map_shadow_stack() is marked as a conditional
syscall in sys_ni.c. Adding it to the syscall tables of other
architectures is harmless and would return ENOSYS when exercised.
Note, map_shadow_stack() was assigned #453 during the merge process
since #452 was taken by fchmodat2().
For Powerpc, map it to sys_ni_syscall() as is the norm for Powerpc
syscall tables.
For Alpha, map_shadow_stack() takes up #563 as Alpha still diverges from
the common syscall numbering system in the other architectures.

The Energy Aware Scheduler (EAS) relies on the schedutil governor.
When moving to/from the schedutil governor, sched domains must be
rebuilt to allow re-evaluating the enablement conditions of EAS.
This is done through sched_cpufreq_governor_change().
Having a cpufreq governor assumes a cpufreq driver is running.
Inserting/removing a cpufreq driver should trigger a re-evaluation
of EAS enablement conditions, avoiding to see EAS enabled when
removing a running cpufreq driver.
Rebuild the sched domains in schedutil's sugov_init()/sugov_exit(),
allowing to check EAS's enablement condition whenever schedutil
governor is initialized/exited from.
Move relevant code up in schedutil.c to avoid a split and conditional
function declaration.

With the schema corrected, a minimal interrupt controller node is needed

Currently, there exists a system-wide setting related to CPU security
mitigations, denoted as 'mitigations='. When set to 'mitigations=off', it
deactivates all optional CPU mitigations. Therefore, if we implement a
system-wide 'mitigations=off' setting, it should inherently bypass Spectre
v1 and Spectre v4 in the BPF subsystem.
Please note that there is also a more specific 'nospectre_v1' setting on
x86 and ppc architectures, though it is not currently exported. For the
time being, let's disregard more fine-grained options.
This idea emerged during our discussion about potential Spectre v1 attacks

In x86 virtualization environments, including TDX, RDTSC instruction is
handled without causing a VM exit, resulting in minimal overhead and
jitters. On the other hand, other clock sources (such as HPET, ACPI
timer, APIC, etc.) necessitate VM exits to implement, resulting in more
fluctuating measurements compared to TSC. Thus, those clock sources are
not effective for calibrating TSC.
As a foundation, the host TSC is guaranteed to be invariant on any
system which enumerates TDX support.
TDX guests and the TDX module build on that foundation by enforcing:
- Virtual TSC is monotonously incrementing for any single VCPU;
- Virtual TSC values are consistent among all the TD’s VCPUs at the
level supported by the CPU:
+ VMM is required to set the same TSC_ADJUST;
+ VMM must not modify from initial value of TSC_ADJUST before
SEAMCALL;
- The frequency is determined by TD configuration:
+ Virtual TSC frequency is specified by VMM on TDH.MNG.INIT;
+ Virtual TSC starts counting from 0 at TDH.MNG.INIT;
The result is that a reliable TSC is a TDX architectural guarantee.
Use the TSC as the only reliable clock source in TD guests, bypassing
unstable calibration.
This is similar to what the kernel already does in some VMWare and
HyperV environments.

Add void *context arrgument to the list of arguments of
acpi_dev_install_notify_handler() and modify it to pass that argument
as context to acpi_install_notify_handler() instead of its first
argument which is problematic in general (for example, if platform
drivers used it, they would rather get struct platform_device pointers
or pointers to their private data from the context arguments of their
notify handlers).
Make all of the current callers of acpi_dev_install_notify_handler()
take this change into account so as to avoid altering the general
functionality.

In some cases, ACPI drivers are implemented as a way to manage devices
enumerated with the help of the platform firmware through ACPI.
This might be confusing, since the preferred way to implement a driver
for a device that cannot be enumerated natively, is a platform
driver, as stated in the documentation.
Clarify relationships between ACPI device objects, platform devices and
ACPI Namespace entries.

The computation of endpoint memory access descriptor's composite memory
region descriptor offset is using COMPOSITE_CONSTITUENTS_OFFSET which is
unnecessary complicated. Composite memory region descriptor always follow
the endpoint memory access descriptor array and hence it is computed
accordingly. COMPOSITE_CONSTITUENTS_OFFSET is useless and wrong for any
input other than endpoint memory access descriptor count.
Let us drop the usage of COMPOSITE_CONSTITUENTS_OFFSET to simplify the
computation of total transmit and fragment length in the memory
transactions.
