Introduce a new SMC command INTEL_SIP_SMC_FUNCID_SERVICE_COMPLETED
that polls if a previous asynchronous command was completed. This
SMC command is used by the new FPGA Crypto Service (FCS).
A basic example is that the FCS sends an AES data encryption
call to the secure device manager(SDM) and waits for the completion
of the operation by continuously polling the results with the new
command.

Extend Intel service layer driver to support FPGA Crypto service(FCS)
features on Intel Soc platforms. Adding an additional channel and FCS
platform driver ("intel_fcs") as part of the probe method.
FCS driver uses the driver to send crypto operations' commands to
the secure device manager(SDM) on Intel Soc platforms Stratix10 and
Agilex.

This introduces a new driver that requests interconnect bandwidth based
on throughput measurements of the bwmon hardware blocks found associated
with, among other things, the CPU subsystem on many Qualcomm platforms.
It introduces support for the SCM wrapper driver to vote for
interconnect bandwidth for operations that needs bandwidth to the crypto
engine. This ensures both performance and guards against issues caused
by lacking votes for this path.
The socinfo driver gains knowledge about the SC7180P SoC.
It contains a range of fixes for spelling mistakes, refcount leaks in
various drivers and removes some redundant code from the apr remove
path.
The SCM DT bindings are updated to declare support for QCS404, SM6125
and SDX65.
The command db driver has a strncpy() converted to strscpy_pad() and
then back again with proper documentation to why this was the right API.

Commit 98f30d0ecf ("ACPI: power: Switch to sys-off handler API")
switched the ACPI sleep code from directly setting the old global
pm_power_off handler to using the new register_sys_off_handler()
mechanism with a priority of SYS_OFF_PRIO_FIRMWARE.
This is a problem when the old global pm_power_off handler would later
be overwritten, such as done by the late_initcall(efi_shutdown_init):
if (efi_poweroff_required())
pm_power_off = efi_power_off;
The old global pm_power_off handler gets run with a priority of
SYS_OFF_PRIO_DEFAULT which is lower then SYS_OFF_PRIO_FIRMWARE, causing
acpi_power_off() to run first, changing the behavior from before
the ACPI sleep code switched to the new register_sys_off_handler().
Switch the registering of efi_power_off over to register_sys_off_handler()
with a priority of SYS_OFF_PRIO_FIRMWARE + 1 so that it will run before
acpi_power_off() as before.
Note since the new sys-off-handler code will try all handlers in
priority order, there is no more need for the EFI code to store and
call the original pm_power_off handler.

The main additions this time around are:
1. The capability to trace full SCMI message headers and payloads.
The recent unearthing of chain of old firmware issues motivated
this effort so that it is easier to trace them and debug quicker
than it took this time around in absence of such tracing.
2. SCMI System power control driver to handle platform's requests for a
graceful shutdown. Though the system power control protocol has been
around since the begining of SCMI, it lacked the timeout information
that was added in SCMI v3.1 that enables kernel to take appropriate
action within the timeout and doesn't have to rely on any other
user inputs(which was blocking factor for addition of this driver
earlier)
3. Support for SCMI Power Capping protocol that was introduced in SCMI v3.1
This protocol is intended for controlling and monitoring the power
consumption of power capping domains. The firmware also provides the
hierarchy of powercap domains by providing parent domain information.
It also contains a bug fix in the old SCPI driver addressing possible
user-after-free issues.

Add a method to get hold of a protocol, causing it to be initialized and
its resource accounting updated, without getting access to its operations
and handle.
Some protocols, like SCMI SystemPower, do not expose any protocol ops to
the kernel OSPM agent but still need to be at least initialized. This
helper avoids the need to invoke a full devm_get_protocol() only to get
the protocol initialized while throwing away unused the protocol ops and

SGI interrupt register and reset is performed by EEMI ioctl
IOCTL_REGISTER_SGI. However, this is not correct use of EEMI call.
SGI registration functionality does not qualify as energy management
activity and so shouldn't be mapped to EEMI call.
This new call will replace IOCTL_REGISTER_SGI and will be handled by TF-A
specific handler in TF-A. To maintain backward compatibility for a while
firmware driver will still use IOCTL_REGISTER_SGI as fallback strategy if
new call fails or is not supported by TF-A.
This new design also helps to make TF-A as pass through layer for EEMI
calls. So we don't have to maintain PM_IOCTL as EEMI API ID in TF-A.

Move the fiddly bits of the efivar layer into its only remaining user,
efivarfs, and confine its use to that particular module. All other uses
of the EFI variable store have no need for this additional layer of
complexity, given that they either only read variables, or read and
write variables into a separate GUIDed namespace, and cannot be used to

__efivar_entry_iter() uses a list iterator in a dubious way, i.e., it
assumes that the iteration variable always points to an object of the
appropriate type, even if the list traversal exhausts the list
completely, in which case it will point somewhere in the vicinity of the
list's anchor instead.
Fortunately, we no longer use this function so we can just get rid of it
entirely.

Switch the caching linked-list efivars layer implementation to the newly

Both efivars and efivarfs uses __efivar_entry_iter() to go over the
linked list that shadows the list of EFI variables held by the firmware,
but fail to call the begin/end helpers that are documented as a
prerequisite.
So switch to the proper version, which is efivar_entry_iter(). Given
that in both cases, efivar_entry_remove() is invoked with the lock held
already, don't take the lock there anymore.

Commit 5d9db88376 ("efi: Add support for a UEFI variable filesystem")
dated Oct 5, 2012, introduced a new efivarfs pseudo-filesystem to
replace the efivars sysfs interface that was used up to that point to
expose EFI variables to user space.
The main problem with the sysfs interface was that it only supported up
to 1024 bytes of payload per file, whereas the underlying variables
themselves are only bounded by a platform specific per-variable and
global limit that is typically much higher than 1024 bytes.
The deprecated sysfs interface is only enabled on x86 and Itanium, other
EFI enabled architectures only support the efivarfs pseudo-filesystem.
So let's finally rip off the band aid, and drop the old interface
entirely. This will make it easier to refactor and clean up the
underlying infrastructure that is shared between efivars, efivarfs and
efi-pstore, and is long overdue for a makeover.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
Avoid the efivars layer and simply call the newly introduced EFI
varstore helpers instead. This simplifies the code substantially, and
also allows us to remove some hacks in the shared efivars layer that
were added for efi-pstore specifically.
In order to be able to delete the EFI variable associated with a record,
store the UTF-16 name of the variable in the pstore record's priv field.
That way, we don't have to make guesses regarding which variable the
record may have been loaded from.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
The current efivars layer is a jumble of list iterators, shadow data
structures and safe variable manipulation helpers that really belong in
the efivarfs pseudo file system once the obsolete sysfs access method to
EFI variables is removed.
So split off a minimal efivar get/set variable API that reuses the
existing efivars_lock semaphore to mediate access to the various runtime
services, primarily to ensure that performing a SetVariable() on one CPU
while another is calling GetNextVariable() in a loop to enumerate the
contents of the EFI variable store does not result in surprises.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
Even though the efivars_lock lock is documented as protecting the
efivars->ops pointer (among other things), efivar_init() happily
releases and reacquires the lock for every EFI variable that it
enumerates. This used to be needed because the lock was originally a
spinlock, which prevented the callback that is invoked for every
variable from being able to sleep. However, releasing the lock could
potentially invalidate the ops pointer, but more importantly, it might
allow a SetVariable() runtime service call to take place concurrently,
and the UEFI spec does not define how this affects an enumeration that
is running in parallel using the GetNextVariable() runtime service,
which is what efivar_init() uses.
In the meantime, the lock has been converted into a semaphore, and the
only reason we need to drop the lock is because the efivarfs pseudo
filesystem driver will otherwise deadlock when it invokes the efivars
API from the callback to create the efivar_entry items and insert them
into the linked list. (EFI pstore is affected in a similar way)
So let's switch to helpers that can be used while the lock is already
taken. This way, we can hold on to the lock throughout the enumeration.

The efivars intermediate variable access layer provides an abstraction
that permits the EFI variable store to be replaced by something else
that implements a compatible interface, and caches all variables in the
variable store for fast access via the efivarfs pseudo-filesystem.
The SSDT override feature does not take advantage of either feature, as
it is only used when the generic EFI implementation of efivars is used,
and it traverses all variables only once to find the ones it is
interested in, and frees all data structures that the efivars layer
keeps right after.
So in this case, let's just call EFI's code directly, using the function
pointers in struct efi.

A reply to CLOCK_DESCRIBE_RATES issued against a non rate-discrete clock
should be composed of a triplet of rates descriptors (min/max/step)
returned all in one reply message.
This is not always the case when dealing with some SCMI server deployed in
the wild: relax such constraint while maintaining memory safety by checking
carefully the returned payload size.
While at that cleanup a stale debug printout.

Commit b05b9f5f9d ("x86, mirror: x86 enabling - find mirrored memory
ranges") introduce the efi_find_mirror() function on x86. In order to reuse
the API we make it public.
Arm64 can support mirrored memory too, so function efi_find_mirror() is added to
efi_init() to this support for arm64.
Since efi_init() is shared by ARM, arm64 and riscv, this patch will bring
mirror memory support for these architectures, but this support is only tested
in arm64.

scmi_voltage_descriptors_get() will incorrecly return an error code if
the last iteration of the for loop that retrieves the descriptors is
skipped due to an error. Skipping an iteration in the loop is not an
error, but the `ret` value from the last iteration will be propagated
when the function returns.
Fix by not saving return values that should not be propagated. This
solution also minimizes the risk of future patches accidentally
re-introducing this bug.

Commit b260fccaeb ("firmware: arm_scmi: Add SCMI v3.1 protocol extended
names support") moved all the name string buffers to use the extended buffer
size of 64 instead of the required 16 bytes. While that should be fine if
the firmware terminates the string before 16 bytes, there is possibility
of copying random data if the name is not NULL terminated by the firmware.
SCMI base protocol agent_name/vendor_id/sub_vendor_id are defined by the
specification as NULL-terminated ASCII strings up to 16-bytes in length.
The underlying buffers and message descriptors are currently bigger than
needed; resize them to fit only the strictly needed 16 bytes to avoid
any possible leaks when reading data from the firmware.
Change the size argument of strlcpy to use SCMI_SHORT_NAME_MAX_SIZE always
when dealing with short domain names, so as to limit the possibility that
an ill-formed non-NULL terminated short reply from the SCMI platform
firmware can leak stale content laying in the underlying transport shared
memory area.
While at that, convert all strings handling routines to use the preferred
strscpy.

Here is the large set of char, misc, and other driver subsystem updates
for 5.19-rc1. The merge request for this has been delayed as I wanted
to get lots of linux-next testing due to some late arrivals of changes
for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers
and cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device

- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that
below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no reported
problems.
Note, there are 3 merge conflicts when merging this with your tree:
- MAINTAINERS, should be easy to resolve
- drivers/slimbus/qcom-ctrl.c, should be straightforward
resolution
- drivers/misc/lkdtm/stackleak.c, not an easy resolution. This
has been noted in the linux-next tree for a while, and
resolved there, here's a link to the resolution that Stephen
came up with and that Kees says is correct:

Geert reports that the new option CONFIG_EFI_DISABLE_RUNTIME is user
visible even when EFI support is disabled, which is unnecessary and
clutters the Kconfig interface.
So let's move this option into the existing Kconfig submenu that already
depends on CONFIG_EFI, and while at it, give some other options the same
treatment.
Also clean up a small wart where the efi/ subdirectory is listed twice.
Let's just list it unconditionally so that both EFI and UEFI_CPER based
pieces will be built independently (the latter only depends on the
former on !X86)

The newly added DXE calls use 64-bit quantities, which means we need to
marshall them explicitly when running in mixed mode. Currently, we get
away without it because we just bail when GetMemorySpaceDescriptor()
fails, which is guaranteed to happen due to the function argument mixup.
Let's fix this properly, though, by defining the macros that describe
how to marshall the arguments. While at it, drop an incorrect cast on a
status variable.

An inclusion of cache.h in printk.h was added in 2014 in commit
c28aa1f0a8 ("printk/cache: mark printk_once test variable
__read_mostly") in order to bring in the definition of __read_mostly. The
usage of __read_mostly was later removed in commit 3ec25826ae ("printk:
Tie printk_once / printk_deferred_once into .data.once for reset") which
made the inclusion of cache.h unnecessary, so remove it.
We have a small amount of code that depended on the inclusion of cache.h
from printk.h; fix that code to include the appropriate header.
This fixes a circular inclusion on arm64 (linux/printk.h -> linux/cache.h
-> asm/cache.h -> linux/kasan-enabled.h -> linux/static_key.h ->
linux/jump_label.h -> linux/bug.h -> asm/bug.h -> linux/printk.h) that
would otherwise be introduced by the next patch.
Build tested using {allyesconfig,defconfig} x {arm64,x86_64}.

This converts a wide range of Qualcomm-related DeviceTree bindings to
YAML, in order to improve our ability to validate the DeviceTree source.
The RPMh power-domain driver gains support for the modem platform SDX65,
the compute platform SC8280XP and the automotive platform SA8540p. While
LLCC gains support for SC8180X and SC8280XP and gains a
MODULE_DEVICE_TABLE() to make it functional as a module.
It adds a driver for configuring the SSC bus, providing Linux access to
the hardware blocks in the sensor subsystem.
The socinfo driver gets confusion related to MSM8974 Pro sorted out and
adds new ids for SM8540 and SC7280.
The SCM driver gains support for MSM8974.
Add missing of_node_put() in smp2p and smsm drivers.
Stop using iterator after list_for_each_entry() and define static
definitions as such, in the PDR driver.

If the system exposes memory regions with the EFI_MORE_RELIABLE
attribute, it is implied that it is intended to be used for allocations
that are relatively important, such as the kernel's static image.
Since efi_random_alloc() is mostly (only) used for allocating space for
the kernel image, let's update it to take this into account, and
disregard all memory without the EFI_MORE_RELIABLE attribute if there is
sufficient memory available that does have this attribute.
Note that this change only affects booting with randomization enabled.
In other cases, the EFI stub runs the kernel image in place unless its
placement is unsuitable for some reason (i.e., misaligned, or its BSS
overlaps with another allocation), and it is left to the bootloader to
ensure that the kernel was loaded into EFI_MORE_RELIABLE memory if this
is desired.

The main theme for most of the changes this time is around the addition
of the support for SCMI v3.1 specification changes. Though one of the main
addition in the specification is the powercap protocol, that is still
work in progress and this set includes all other changes bit and pieces
scattered all around the different parts of the specification. There are
few bugs discovered during the process and associated fixes and some
refactoring to simplify the addition of v3.1 support. It mainly includes
the support for extended names, few newly added notifications and async
command support.
Apart from v3.1 SCMI changes, OPTEE transport gets support for dynamic
shared memory.

Couple of fixes to handle fragmented memory descriptors and incorrect
UUID parameter passed to ffa_partition_probe. Another fix deals with
the incorrect use of ffa_device's driver_data by the core driver.
Apart from these fixes, there is an addition of ffa_dev_get_drvdata helper
function and its use in optee driver.

Arm FF-A firmware driver updates/fixes for v5.19
Couple of fixes to handle fragmented memory descriptors and incorrect
UUID parameter passed to ffa_partition_probe. Another fix deals with
the incorrect use of ffa_device's driver_data by the core driver.
Apart from these fixes, there is an addition of ffa_dev_get_drvdata helper
function and its use in optee driver.

If the loader has already placed the EFI kernel image randomly in
physical memory, and indicates having done so by installing the 'fixed
placement' protocol onto the image handle, don't bother randomizing the
placement again in the EFI stub.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
In a future patch, arm64's implementation of handle_kernel_image() will
omit randomizing the placement of the kernel if the load address was
chosen randomly by the loader. In order to do this, it needs to locate a
protocol on the image handle, so pass it to handle_kernel_image().

During system suspend it is completely valid for devices to invoke TISCI
commands during the noirq phase of the suspend path. Specifically this
will always be seen for devices that define a power-domains DT property
and make use of the ti_sci_pm_domains genpd implementation.
The genpd_finish_suspend call will power off devices during the noirq
phase, which will invoke TISCI.
In order to support this, the ti_sci driver must switch to not use
wait_for_completion_timeout during suspend, but instead rely on a manual
check for if the completion is not yet done, and proceed only if this is
the case.

Currently the value of 0 is assigned as is and is propogated to the clock

Move away from a statically allocated array for holding the current set of

dynamically based on the number of protocols effectively advertised by the
platform via BASE protocol exchanges.
While at that, rectify the BASE_DISCOVER_LIST_PROTOCOLS loop iterations to
terminate only when a number of protocols equal to the advertised ones has
been received, instead of looping till the platform returns no more
protocols descriptors. This new behaviour is better compliant with the
specification and it has been tested to work equally well against an SCMI

The current implementation expects a FFA_MEM_SHARE/FFA_MEM_LEND

case where a full descriptor does not fit inside the partitions
TX buffer, the call can instead complete with a FFA_MEM_FRAG_RX SMC

Similarly a FFA_MEM_FRAG_TX call currently only expects
FFA_MEM_FRAG_RX as a response, however once the full descriptor
has been transmitted the FFA_SUCCESS ABI will be used to indicate
successful transmission.

populated, the driver will not load (but the platform device will still
be registered).

Confidential computing (coco) hardware such as AMD SEV (Secure Encrypted
Virtualization) allows a guest owner to inject secrets into the VMs
memory without the host/hypervisor being able to read them.
Firmware support for secret injection is available in OVMF, which
reserves a memory area for secret injection and includes a pointer to it
the in EFI config table entry LINUX_EFI_COCO_SECRET_TABLE_GUID.
If EFI exposes such a table entry, uefi_init() will keep a pointer to
the EFI config table entry in efi.coco_secret, so it can be used later
by the kernel (specifically drivers/virt/coco/efi_secret). It will also
appear in the kernel log as "CocoSecret=ADDRESS"; for example:
[ 0.000000] efi: EFI v2.70 by EDK II
[ 0.000000] efi: CocoSecret=0x7f22e680 SMBIOS=0x7f541000 ACPI=0x7f77e000 ACPI 2.0=0x7f77e014 MEMATTR=0x7ea0c018
The new functionality can be enabled with CONFIG_EFI_COCO_SECRET=y.

Commit d9f283ae71 ("efi: Disable runtime services on RT") disabled EFI
runtime services by default when the CONFIG_PREEMPT_RT option is enabled.
The rationale for that commit is that some EFI calls could take too much
time, leading to large latencies which is an issue for Real-Time kernels.
But a side effect of that change was that now is not possible anymore to
enable the EFI runtime services by default when CONFIG_PREEMPT_RT is set,
without passing an efi=runtime command line parameter to the kernel.
Instead, let's add a new EFI_DISABLE_RUNTIME boolean Kconfig option, that
would be set to n by default but to y if CONFIG_PREEMPT_RT is enabled.
That way, the current behaviour is preserved but gives users a mechanism
to enable the EFI runtimes services in their kernels if that is required.
For example, if the firmware could guarantee bounded time for EFI calls.
Also, having a separate boolean config could allow users to disable the
EFI runtime services by default even when CONFIG_PREEMPT_RT is not set.

For wmfw format v2 and later the coefficient name strings have a length
field and are NOT null-terminated. Use kasprintf() to convert the
unterminated string into a null-terminated string in an allocated buffer.
The previous code handled this duplication incorrectly using kmemdup()
and getting the length from a strlen() of the (unterminated) source string.
This resulted in creating a string that continued up to the next byte in
the firmware file that just happened to be 0x00.

The sparse checker complains about converting pointers between address
spaces. We correctly stored an __iomem pointer in struct scmi_optee_channel,
but discarded the __iomem when returning it from get_channel_shm, causing one
warning. Then we passed the non-__iomem pointer return from get_channel_shm
at two other places, where an __iomem pointer is expected, causing couple of
other warnings
Add the appropriate __iomem annotations at all places where it is missing.

During SCMI Clock protocol initialization, after having retrieved from the
SCMI platform all the available discrete rates for a specific clock, the
clock rates array is sorted, unfortunately using a pointer to its end as
a base instead of its start, so that sorting does not work.
Fix invocation of sort() passing as base a pointer to the start of the
retrieved clock rates array.

On SCMI transports whose channels are based on a shared resource the TX
channel area has to be acquired by the agent before placing the desired
command into the channel and it will be then relinquished by the platform
once the related reply has been made available into the channel.
On an RX channel the logic is reversed with the platform acquiring the
channel area and the agent reliquishing it once done by calling the
scmi_clear_channel() helper.
As a consequence, even in case of error, the agent must never try to clear
a TX channel from its side: restrict the existing clear channel call on the
the reply path only to delayed responses since they are indeed coming from
the RX channel.

Pull ACPI updates from Rafael Wysocki:
"From the new functionality perspective, the most significant items
here are the new driver for the 'ARM Generic Diagnostic Dump and
Reset' device, the extension of fine grain fan control in the ACPI fan
driver, and the change making it possible to use CPPC information to
obtain CPU capacity.
There are also a few new quirks, a bunch of fixes, including the
platform-level _OSC handling change to make it actually take the
platform firmware response into account, some code and documentation
cleanups, and a notable update of the ACPI device enumeration

Pull tpm updates from Jarkko Sakkinen:
"In order to split the work a bit we've aligned with David Howells more
or less that I take more hardware/firmware aligned keyring patches,
and he takes care more of the framework aligned patches.
For TPM the patches worth of highlighting are the fixes for
refcounting provided by Lino Sanfilippo and James Bottomley.
Eric B. has done a bunch obvious (but important) fixes but there's one
a bit controversial: removal of asym_tpm. It was added in 2018 when
TPM1 was already declared as insecure and world had moved on to TPM2.
I don't know how this has passed all the filters but I did not have a
chance to see the patches when they were out. I simply cannot commit
to maintaining this because it was from all angles just wrong to take
it in the first place to the mainline kernel. Nobody should use this
module really for anything.
Finally, there is a new keyring '.machine' to hold MOK keys ('Machine
Owner Keys'). In the mok side MokListTrustedRT UEFI variable can be
set, from which kernel knows that MOK keys are kernel trusted keys and
they are populated to the machine keyring. This keyring linked to the
secondary trusted keyring, which means that can be used like any
kernel trusted keys. This keyring of course can be used to hold other
MOK'ish keys in other platforms in future"

pstore_dump() is *always* invoked in atomic context (nowadays in an RCU
read-side critical section, before that under a spinlock).
It doesn't make sense to try to use semaphores here.
This is mostly a revert of commit ea84b580b9 ("pstore: Convert buf_lock
to semaphore"), except that two parts aren't restored back exactly as they
were:
- keep the lock initialization in pstore_register
- in efi_pstore_write(), always set the "block" flag to false
- omit "is_locked", that was unnecessary since
commit 959217c84c ("pstore: Actually give up during locking failure")
- fix the bailout message
The actual problem that the buggy commit was trying to address may have
been that the use of preemptible() in efi_pstore_write() was wrong - it
only looks at preempt_count() and the state of IRQs, but __rcu_read_lock()
doesn't touch either of those under CONFIG_PREEMPT_RCU.
(Sidenote: CONFIG_PREEMPT_RCU means that the scheduler can preempt tasks in
RCU read-side critical sections, but you're not allowed to actively
block/reschedule.)
Lockdep probably never caught the problem because it's very rare that you
actually hit the contended case, so lockdep always just sees the
down_trylock(), not the down_interruptible(), and so it can't tell that
there's a problem.

Since switch to simplefb/simpledrm VESA graphic mode selection with vga=
kernel parameter is no longer available with legacy BIOS.
The x86 realmode boot code enables the VESA graphic modes when option
FB_BOOT_VESA_SUPPORT is enabled.
This option is selected by vesafb but not simplefb/simpledrm.
To enable use of VESA modes with simplefb in legacy BIOS boot mode drop
dependency of BOOT_VESA_SUPPORT on FB, also drop the FB_ prefix. Select
the option from sysfb rather than the drivers that depend on it.
The BOOT_VESA_SUPPORT is not specific to framebuffer but rather to x86
platform, move it from fbdev to x86 Kconfig.

From commit e147133a42 ("ACPI / APEI: Make hest.c manage the estatus
memory pool") was merged, ghes_init() relies on acpi_hest_init() to manage
the estatus memory pool. On the other hand, ghes_init() relies on
sdei_init() to detect the SDEI version and (un)register events. The
dependencies are as follows:
ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init()
ghes_init() => sdei_init()
HEST is not PCI-specific and initcall ordering is implicit and not
well-defined within a level.
Based on above, remove acpi_hest_init() from acpi_pci_root_init() and
convert ghes_init() and sdei_init() from initcalls to explicit calls in the
following order:
acpi_hest_init()
ghes_init()
sdei_init()

This refactors the Qualcomm mdt file loader, to partially decouple it
from the SCM peripheral-authentication-service. This is needed as newer
platforms, such as the Qualcomm SM8450, require the metadata to remain
accessible to TrustZone during a longer time. This is followed by the
introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1).
It changes the way hardware version differences are handled in the LLCC
driver and introduces support for Qualcomm SM8450. While updating the dt
binding for LLCC it also introduces the missing SM8350 compatible.
The ocmem and aoss drivers gains missing put_device() calls and rpmpd
gains a missing check for kcalloc() failure.
The SPM driver is updated to avoid instantiating the SPM cpuidle devices
if the CPUs aren't controlled by SPM, such as when Snapdragon 8916

The RPM power-domain driver gains MSM8226 support.
Lastly the socinfo driver gains knowledge about a few new SoCs and

When "dump_apple_properties" is used on the kernel boot command line,
it causes an Unknown parameter message and the string is added to init's
argument strings:
Unknown kernel command line parameters "dump_apple_properties
BOOT_IMAGE=/boot/bzImage-517rc6 efivar_ssdt=newcpu_ssdt", will be
passed to user space.
Run /sbin/init as init process
with arguments:
/sbin/init
dump_apple_properties
with environment:
HOME=/
TERM=linux
BOOT_IMAGE=/boot/bzImage-517rc6
efivar_ssdt=newcpu_ssdt
Similarly when "efivar_ssdt=somestring" is used, it is added to the
Unknown parameter message and to init's environment strings, polluting
them (see examples above).
Change the return value of the __setup functions to 1 to indicate
that the __setup options have been handled.

The code changes address mostly minor problems:
- Several NXP/FSL SoC driver fixes, addressing issues with error
handling and compilation
- Fix a clock disabling imbalance in gpcv2 driver.
- Arm Juno DMA coherency issue
- Trivial firmware driver fixes for op-tee and scmi firmware
The remaining changes address issues in the devicetree files:
- a timer regression for the OMAP devkit8000, which has to use
the alternative timer.
- A hang in the i.MX8MM power domain configuration
- Multiple fixes for the Rockchip RK3399 addressing issues
with sound and eMMC
- Cosmetic fixes for i.MX8ULP, RK3xxx, and Tegra124

When the "block" flag is false, the old code would sometimes still call
check_var_size(), which wrongly tells ->query_variable_store() that it can
block.
As far as I can tell, this can't really materialize as a bug at the moment,
because ->query_variable_store only does something on X86 with generic EFI,
and in that configuration we always take the efivar_entry_set_nonblocking()
path.
Fixes: ca0e30dcaa ("efi: Add nonblocking option to efi_query_variable_store()")
