It is observed that when thinkpad_acpi driver loads before amd-pmf
driver, thinkpad_acpi driver sends the AMT "on" event and the request
immediately will be part of the PMF BIOS "pending requests".
With the current amd-pmf code, as soon as the amd-pmf driver gets
probed, it calls apmf_acpi_init() where the notify handler will be
installed. Handler callback would call amd_pmf_handle_amt() where the
amd_pmf_set_automode() shall update the auto-mode thermals.
In this case, the auto-mode config_store shall have "zeros", as the
auto mode init gets called during the later stage.
To fix this, change the order of the acpi notifer install and call it
after the auto mode initialization is done.

EFI's SetVirtualAddressMap() runtime service is a horrid hack that we'd
like to avoid using, if possible. For 64-bit architectures such as
arm64, the user and kernel mappings are entirely disjoint, and given
that we use the user region for mapping the UEFI runtime regions when
running under the OS, we don't rely on SetVirtualAddressMap() in the
conventional way, i.e., to permit kernel mappings of the OS to coexist
with kernel region mappings of the firmware regions. This means that, in
principle, we should be able to avoid SetVirtualAddressMap() altogether,
and simply use the 1:1 mapping that UEFI uses at boot time. (Note that
omitting SetVirtualAddressMap() is explicitly permitted by the UEFI
spec).
However, there is a corner case on arm64, which, if configured for
3-level paging (or 2-level paging when using 64k pages), may not be able
to cover the entire range of firmware mappings (which might contain both
memory and MMIO peripheral mappings).
So let's avoid SetVirtualAddressMap() on arm64, but only if the VA space
is guaranteed to be of sufficient size.

LoadImage() is supposed to install an instance of the protocol
EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL onto the loaded image's handle so
that the program can figure out where it was loaded from. The reference
implementation even does this (with a NULL protocol pointer) if the call
to LoadImage() used the source buffer and size arguments, and passed
NULL for the image device path. Hand rolled implementations of LoadImage
may behave differently, though, and so it is better to tolerate
situations where the protocol is missing. And actually, concatenating an
Offset() node to a NULL device path (as we do currently) is not great
either.
So in cases where the protocol is absent, or when it points to NULL,
construct a MemoryMapped() device node as the base node that describes
the parent image's footprint in memory.

The EFI TCG spec, in §10.2.6 "Measuring UEFI Variables and UEFI GPT
Data", only reasons about the load options passed to a loaded image in
the context of boot options booted directly from the BDS, which are
measured into PCR #5 along with the rest of the Boot#### EFI variable.
However, the UEFI spec mentions the following in the documentation of
the LoadImage() boot service and the EFI_LOADED_IMAGE protocol:
The caller may fill in the image’s "load options" data, or add
additional protocol support to the handle before passing control to
the newly loaded image by calling EFI_BOOT_SERVICES.StartImage().
The typical boot sequence for Linux EFI systems is to load GRUB via a
boot option from the BDS, which [hopefully] calls LoadImage to load the
kernel image, passing the kernel command line via the mechanism
described above. This means that we cannot rely on the firmware
implementing TCG measured boot to ensure that the kernel command line
gets measured before the image is started, so the EFI stub will have to
take care of this itself.
Given that PCR #5 has an official use in the TCG measured boot spec,
let's avoid it in this case. Instead, add a measurement in PCR #9 (which
we already use for our initrd) and extend it with the LoadOptions
measurements

using the TCG2 measured boot protocols. A following patch is
introducing measurements of additional components, such as the kernel

types of measured boot that don't expose the TCG2 protocols.
So let's prepare for that, by rejigging the efi_measure_initrd() routine
into something that we should be able to reuse for measuring other
assets, and which can be extended later to support other measured boot
protocols.

Merge tag 'efi-loongarch-for-v6.1-2' into HEAD
Second shared stable tag between EFI and LoongArch trees
This is necessary because the EFI libstub refactoring patches are mostly
directed at enabling LoongArch to wire up generic EFI boot support
without being forced to consume DT properties that conflict with
information that EFI also provides, e.g., memory map and reservations,
etc.
LoongArch does not use FDT or DT natively [yet], and the only reason it
currently uses it is so that it can reuse the existing EFI stub code.
Overloading the DT with data passed between the EFI stub and the core
kernel has been a source of problems: there is the overlap between
information provided by EFI which DT can also provide (initrd base/size,
command line, memory descriptions), requiring us to reason about which
is which and what to prioritize. It has also resulted in ABI leaks,
i.e., internal ABI being promoted to external ABI inadvertently because
the bootloader can set the EFI stub's DT properties as well (e.g.,
"kaslr-seed"). This has become especially problematic with boot
environments that want to pretend that EFI boot is being done (to access
ACPI and SMBIOS tables, for instance) but have no ability to execute the
EFI stub, and so the environment that the EFI stub creates is emulated
[poorly, in some cases].
Another downside of treating DT like this is that the DT binary that the
kernel receives is different from the one created by the firmware, which
is undesirable in the context of secure and measured boot.
Given that LoongArch support in Linux is brand new, we can avoid these
pitfalls, and treat the DT strictly as a hardware description, and use a
separate handover method between the EFI stub and the kernel. Now that
initrd loading and passing the EFI memory map have been refactored into
pure EFI routines that use EFI configuration tables, the only thing we
need to pass directly is the kernel command line (even if we could pass
this via a config table as well, it is used extremely early, so passing
it directly is preferred in this case.)

Merge series from Zhang Qilong <zhangqilong3@huawei.com>:
The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed when error returns to keep it
balanced. This series of patches fixed it in spi probe.
Now that the scratch page and page directories have a reference back to
the i915_address_space, we cannot do an immediate free of the ppgtt upon
error as those buffer objects will perform a later i915_vm_put in their
deferred frees.
The downside is that by replacing the onion unwind along the error
paths, the ppgtt cleanup must handle a partially constructed vm. This
includes ensuring that the vm->cleanup is set prior to the error path.
