Add support for the stackleak feature. Whenever the kernel returns to user
space the kernel stack is filled with a poison value.
At the same time, disables the plugin in EFI stub code because EFI stub
is out of scope for the protection.

Pull driver core updates from Greg KH:
"Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases
to get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions.
It's not all that useful for a "write a whole driver in rust" type
of thing, but the firmware bindings do help out the phy rust
drivers, and the driver core bindings give a solid base on which
others can start their work.
There is still a long way to go here before we have a multitude of
rust drivers being added, but it's a great first step.
- driver core const api changes.
This reached across all bus types, and there are some fix-ups for
some not-common bus types that linux-next and 0-day testing shook
out.
This work is being done to help make the rust bindings more safe,
as well as the C code, moving toward the end-goal of allowing us to
put driver structures into read-only memory. We aren't there yet,
but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems"

Currently, only TLB-based ioremap() support writecombine, so add the
counterpart for DMW-based ioremap() with help of DMW2. The base address
(WRITECOMBINE_BASE) is configured as 0xa000000000000000.
DMW3 is unused by kernel now, however firmware may leave garbage in them
and interfere kernel's address mapping. So clear it as necessary.
BTW, centralize the DMW configuration to macro SETUP_DMWINS.

This is a partial revert of commit
8117961d98f ("x86/efi: Disregard setup header of loaded image")
which triggers boot issues on older Dell laptops. As it turns out,
switching back to a heap allocation for the struct boot_params
constructed by the EFI stub works around this, even though it is unclear
why.

Pull EFI updates from Ard Biesheuvel:
"Note the removal of the EFI fake memory map support - this is believed
to be unused and no longer worth supporting. However, we could easily
bring it back if needed.
With recent developments regarding confidential VMs and unaccepted
memory, combined with kexec, creating a known inaccurate view of the
firmware's memory map and handing it to the OS is a feature we can
live without, hence the removal. Alternatively, I could imagine making
this feature mutually exclusive with those confidential VM related
features, but let's try simply removing it first.
Summary:
- Drop support for the 'fake' EFI memory map on x86
- Add an SMBIOS based tweak to the EFI stub instructing the firmware
on x86 Macbook Pros to keep both GPUs enabled
- Replace 0-sized array with flexible array in EFI memory attributes

While efi_memory_attributes_table_t::entry isn't used directly as an
array, it is used as a base for pointer arithmetic. The type is wrong
as it's not technically an array of efi_memory_desc_t's; they could be
larger. Regardless, leave the type unchanged and remove the old style
"0" array size. Additionally replace the open-coded entry offset code
with the existing efi_memdesc_ptr() helper.

Change the log message of the wmfw format version to include
the file name, and change the message to say "format" instead
of "Firmware version". Merge this with the message that logs
the timestamp.
The wmfw format version is information that is useful to have
logged because the behaviour of firmware controls depends on
the wmfw format. So "unexpected" behaviour could be caused by
having expectations based on one format of wmfw when a
different format has been loaded.
But the original message was confusing. It reported the file
format version but didn't actually log the name of the file it
referred to. It also called it "Firmware version", which is
confusing when a later message also logs a firmware version
that is the version of the actual firmware within the wmfw.
The logging of the firmware timestamp has been merged into this.
That was originally a dbg-only message, but as we are already
logging a line of info, we might as well add a few extra
characters to log the timestamp. The timestamp is now logged
in hexadecimal - it's not particularly useful as a decimal
value.

Don't allocate a temporary buffer to hold a NUL-terminated copy
of the NAME/INFO string from the wmfw/bin. It can be printed
directly to the log. Also limit the maximum number of characters
that will be logged from this string.
The NAME/INFO blocks in the firmware files are an array of
characters with a length, not a NUL-terminated C string. The
original code allocated a temporary buffer to make a
NUL-terminated copy of the string and then passed that to
dev_info(). There's no need for this: printf formatting can
use "%.*s" to print a character array of a given length.

Qualcomm driver updates for v6.11
Support for Shared Memory (shm) Bridge is added, which provides a
stricter interface for handling of buffers passed to TrustZone.
The X1Elite platform is added to uefisecapp allow list, to instantiate
the efivars implementation.
A new in-kernel implementation of the pd-mapper (or servreg) service is
introduced, to replace the userspace dependency for USB Type-C and
battery management.
Support for sharing interrupts across multiple bwmon instances is added,
and a refcount imbalance issue is corrected.
The LLCC support for recent platforms is corrected, and SA8775P support
is added.
A new interface is added to SMEM, to expose "feature codes". One example
of the usecase for this is to indicate to the GPU driver which
frequencies are available on the given device.
The interrupt consumer and provider side of SMP2P is updated to provide
more useful names in interrupt stats.
Support for using the mailbox binding and driver for outgoing IPC
interrupt in the SMSM driver is introduced.
socinfo driver learns about SDM670 and IPQ5321, as well as get some
updates to the X1E PMICs.
pmic_glink is bumped to now support managing 3 USB Type-C ports.

As it turns out, clearing the BSS was not the right fix for the issue
that was ultimately fixed by commit decd347c2a75 ("x86/efistub:
Reinstate soft limit for initrd loading"), and given that the Windows
EFI loader becomes very unhappy when entered with garbage in BSS, this
is one thing that x86 PC EFI implementations can be expected to get
right.
So drop it from the pure PE entrypoint. The handover protocol entrypoint
still needs this - it is used by the flaky distro bootloaders that
barely implement PE/COFF at all.

the integrated GPU has to be enabled. On such dual GPU EFI Macs, the EFI

This patch is also applicable for some non T2 Intel Macs.

In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *. This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.
Because the match() callback is in all busses, all busses are modified
to handle this properly. This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.
For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

Add a check to cs_dsp_coeff_write_ctrl() to abort if the control
is not writeable.
The cs_dsp code originated as an ASoC driver (wm_adsp) where all
controls were exported as ALSA controls. It relied on ALSA to
enforce the read-only permission. Now that the code has been
separated from ALSA/ASoC it must perform its own permission check.
This isn't currently causing any problems so there shouldn't be any
need to backport this. If the client of cs_dsp exposes the control as
an ALSA control, it should set permissions on that ALSA control to
protect it. The few uses of cs_dsp_coeff_write_ctrl() inside drivers
are for writable controls.

Between kexec and confidential VM support, handling the EFI memory maps
correctly on x86 is already proving to be rather difficult (as opposed
to other EFI architectures which manage to never modify the EFI memory
map to begin with)
EFI fake memory map support is essentially a development hack (for
testing new support for the 'special purpose' and 'more reliable' EFI
memory attributes) that leaked into production code. The regions marked
in this manner are not actually recognized as such by the firmware
itself or the EFI stub (and never have), and marking memory as 'more
reliable' seems rather futile if the underlying memory is just ordinary
RAM.
Marking memory as 'special purpose' in this way is also dubious, but may
be in use in production code nonetheless. However, the same should be
achievable by using the memmap= command line option with the ! operator.
EFI fake memmap support is not enabled by any of the major distros
(Debian, Fedora, SUSE, Ubuntu) and does not exist on other
architectures, so let's drop support for it.
