f8b53cc917 efi: Fix .data section size calculations when .sbat is present 
Commit 0f9a1739dd ("efi: zboot specific mechanism for embedding SBAT
section") neglected to adjust the sizes of the .data section when
CONFIG_EFI_SBAT_FILE is set. As the result, the produced PE binary is
incorrect and some tools complain about it. E.g. 'sbsign' reports:

 # sbsign --key my.key --cert my.crt arch/arm64/boot/vmlinuz.efi
 warning: file-aligned section .data extends beyond end of file
 warning: checksum areas are greater than image size. Invalid section table?

Note, '__data_size' is also used in the PE optional header and it is not
entirely clear whether .sbat needs to be accounted as part of
SizeOfInitializedData or not. As the header seems to be unused by the real
world firmware, keeping the field equal to __data_size.

8d2c2fa220 firmware: exynos-acpm: fix timeouts on xfers handling 
The mailbox framework has a single inflight request at a time. If
a request is sent while another is still active, it will be queued
to the mailbox core ring buffer.

ACPM protocol did not serialize the calls to the mailbox subsystem so we
could start the timeout ticks in parallel for multiple requests, while
just one was being inflight.

Consider a hypothetical case where the xfer timeout is 100ms and an ACPM
transaction takes 90ms:
      | 0ms: Message #0 is queued in mailbox layer and sent out, then sits
      |      at acpm_dequeue_by_polling() with a timeout of 100ms
      | 1ms: Message #1 is queued in mailbox layer but not sent out yet.
      |      Since send_message() doesn't block, it also sits at
      |      acpm_dequeue_by_polling() with a timeout of 100ms
      |  ...
      | 90ms: Message #0 is completed, txdone is called and message #1 is sent
      | 101ms: Message #1 times out since the count started at 1ms. Even though
      |       it has only been inflight for 11ms.

Fix the problem by moving mbox_send_message() and mbox_client_txdone()
immediately after the message has been written to the TX queue and while
still keeping the ACPM TX queue lock. We thus tie together the TX write
with the doorbell ring and mark the TX as done after the doorbell has
been rung. This guarantees that the doorbell has been rang before
starting the timeout ticks. We should also see some performance
improvement as we no longer wait to receive a response before ringing
the doorbell for the next request, so the ACPM firmware shall be able to
drain faster the TX queue. Another benefit is that requests are no
longer able to ring the doorbell one for the other, so it eases
debugging. Finally, the mailbox software queue will always contain a
single doorbell request due to the serialization done at the ACPM TX
queue level. Protocols like ACPM, that handle their own hardware queues
need a passthrough mailbox API, where they are able to just ring the
doorbell or flip a bit directly into the mailbox controller. The mailbox
software queue mechanism, the locking done into the mailbox core is not
really needed, so hopefully this lays the foundation for a passthrough
mailbox API.

9ca7a42122 firmware: arm_ffa: Replace mutex with rwlock to avoid sleep in atomic context 
The current use of a mutex to protect the notifier hashtable accesses
can lead to issues in the atomic context. It results in the below
kernel warnings:

  |  BUG: sleeping function called from invalid context at kernel/locking/mutex.c:258
  |  in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 9, name: kworker/0:0

  |   kthread+0x13c/0x210
  |   ret_from_fork+0x10/0x20

To address this, replace the mutex with an rwlock to protect the notifier
hashtable accesses. This ensures that read-side locking does not sleep and
multiple readers can acquire the lock concurrently, avoiding unnecessary
contention and potential deadlocks. Writer access remains exclusive,
preserving correctness.

This change resolves warnings from lockdep about potential sleep in
atomic context.

27e850c88d firmware: arm_ffa: Move memory allocation outside the mutex locking 
The notifier callback node allocation is currently done while holding
the notify_lock mutex. While this is safe even if memory allocation may
sleep, we need to move the allocation outside the locked region in
preparation to move from using muxtes to rwlocks.

Move the memory allocation to avoid potential sleeping in atomic context
once the locks are moved from mutex to rwlocks.

a833d31ad8 firmware: arm_ffa: Fix memory leak by freeing notifier callback node 
Commit e0573444ed ("firmware: arm_ffa: Add interfaces to request
notification callbacks") adds support for notifier callbacks by allocating
and inserting a callback node into a hashtable during registration of
notifiers. However, during unregistration, the code only removes the
node from the hashtable without freeing the associated memory, resulting
in a memory leak.

Resolve the memory leak issue by ensuring the allocated notifier callback
node is properly freed after it is removed from the hashtable entry.

f670b50ef5 sysfb: Fix screen_info type check for VGA 
Use the helper screen_info_video_type() to get the framebuffer
type from struct screen_info. Handle supported values in sorted
switch statement.

Reading orig_video_isVGA is unreliable. On most systems it is a
VIDEO_TYPE_ constant. On some systems with VGA it is simply set
to 1 to signal the presence of a VGA output. See vga_probe() for
an example. Retrieving the screen_info type with the helper
screen_info_video_type() detects these cases and returns the
appropriate VIDEO_TYPE_ constant. For VGA, sysfb creates a device
named "vga-framebuffer".

The sysfb code has been taken from vga16fb, where it likely didn't
work correctly either. With this bugfix applied, vga16fb loads for
compatible vga-framebuffer devices.

Pull EFI updates from Ard Biesheuvel:
 "Not a lot going on in the EFI tree this cycle. The only thing that
  stands out is the new support for SBAT metadata, which was a bit
  contentious when it was first proposed, because in the initial
  incarnation, it would have required us to maintain a revocation index,
  and bump it each time a vulnerability affecting UEFI secure boot got
  fixed. This was shot down for obvious reasons.

  This time, only the changes needed to emit the SBAT section into the
  PE/COFF image are being carried upstream, and it is up to the distros
  to decide what to put in there when creating and signing the build.

  This only has the EFI zboot bits (which the distros will be using for
  arm64); the x86 bzImage changes should be arriving next cycle,
  presumably via the -tip tree.

  Summary:

   - Add support for emitting a .sbat section into the EFI zboot image,
     so that downstreams can easily include revocation metadata in the
     signed EFI images

   - Align PE symbolic constant names with other projects

Add support for the stackleak feature. It initializes the stack with the
poison value before returning from system calls which improves the kernel

At the same time, disables the plugin in EFI stub code because EFI stub
is out of scope for the protection.

47cf96fbe3 arm64 updates for 6.16 
ACPI, EFI and PSCI:
  - Decouple Arm's "Software Delegated Exception Interface" (SDEI)
    support from the ACPI GHES code so that it can be used by platforms
    booted with device-tree.
 
  - Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
    runtime calls.
 
  - Fix a node refcount imbalance in the PSCI device-tree code.
 
 CPU Features:
  - Ensure register sanitisation is applied to fields in ID_AA64MMFR4.
 
  - Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM guests
    can reliably query the underlying CPU types from the VMM.
 
  - Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
    to our context-switching, signal handling and ptrace code.
 
 Entry code:
  - Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be
    selected.
 
 Memory management:
  - Prevent BSS exports from being used by the early PI code.
 
  - Propagate level and stride information to the low-level TLB
    invalidation routines when operating on hugetlb entries.
 
  - Use the page-table contiguous hint for vmap() mappings with
    VM_ALLOW_HUGE_VMAP where possible.
 
  - Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode"
    and hook this up on arm64 so that the trailing DSB (used to publish
    the updates to the hardware walker) can be deferred until the end of
    the mapping operation.
 
  - Extend mmap() randomisation for 52-bit virtual addresses (on par with
    48-bit addressing) and remove limited support for randomisation of
    the linear map.
 
 Perf and PMUs:
  - Add support for probing the CMN-S3 driver using ACPI.
 
  - Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers.
 
 Selftests:
  - Fix FPSIMD and SME tests to align with the freshly re-enabled SME
    support.
 
  - Fix default setting of the OUTPUT variable so that tests are
    installed in the right location.
 
 vDSO:
  - Replace raw counter access from inline assembly code with a call to
    the the __arch_counter_get_cntvct() helper function.
 
 Miscellaneous:
  - Add some missing header inclusions to the CCA headers.
 
  - Rework rendering of /proc/cpuinfo to follow the x86-approach and
    avoid repeated buffer expansion (the user-visible format remains
    identical).
 
  - Remove redundant selection of CONFIG_CRC32
 
  - Extend early error message when failing to map the device-tree blob.

   - Decouple Arm's "Software Delegated Exception Interface" (SDEI)
     support from the ACPI GHES code so that it can be used by platforms
     booted with device-tree

   - Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
     runtime calls

   - Fix a node refcount imbalance in the PSCI device-tree code

  CPU Features:

   - Ensure register sanitisation is applied to fields in ID_AA64MMFR4

   - Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM
     guests can reliably query the underlying CPU types from the VMM

   - Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
     to our context-switching, signal handling and ptrace code

  Entry code:

   - Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be
     selected

  Memory management:

   - Prevent BSS exports from being used by the early PI code

   - Propagate level and stride information to the low-level TLB
     invalidation routines when operating on hugetlb entries

   - Use the page-table contiguous hint for vmap() mappings with
     VM_ALLOW_HUGE_VMAP where possible

   - Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode"
     and hook this up on arm64 so that the trailing DSB (used to publish
     the updates to the hardware walker) can be deferred until the end
     of the mapping operation

   - Extend mmap() randomisation for 52-bit virtual addresses (on par
     with 48-bit addressing) and remove limited support for
     randomisation of the linear map

  Perf and PMUs:

   - Add support for probing the CMN-S3 driver using ACPI

   - Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers

  Selftests:

   - Fix FPSIMD and SME tests to align with the freshly re-enabled SME
     support

   - Fix default setting of the OUTPUT variable so that tests are
     installed in the right location

  vDSO:

   - Replace raw counter access from inline assembly code with a call to
     the the __arch_counter_get_cntvct() helper function

  Miscellaneous:

   - Add some missing header inclusions to the CCA headers

   - Rework rendering of /proc/cpuinfo to follow the x86-approach and
     avoid repeated buffer expansion (the user-visible format remains
     identical)

   - Remove redundant selection of CONFIG_CRC32

   - Extend early error message when failing to map the device-tree
     blob"

Pull drm updates from Dave Airlie:
 "As part of building up nova-core/nova-drm pieces we've brought in some
  rust abstractions through this tree, aux bus being the main one, with
  devres changes also in the driver-core tree. Along with the drm core
  abstractions and enough nova-core/nova-drm to use them. This is still
  all stub work under construction, to build the nova driver upstream.

  The other big NVIDIA related one is nouveau adds support for
  Hopper/Blackwell GPUs, this required a new GSP firmware update to
  570.144, and a bunch of rework in order to support multiple fw
  interfaces.

  There is also the introduction of an asahi uapi header file as a
  precursor to getting the real driver in later, but to unblock
  userspace mesa packages while the driver is trapped behind rust
  enablement.

  Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,
  and msm being the main ones, and some changes to vsprintf.

 - Continued cleanups and helper usages in allover places
 - Support for a wider range of Intel AVS platforms
 - Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32
   Everest Semiconductor ES8375 and ES8389, Longsoon-1 AC'97
   controllers, nVidia Tegra264, Richtek ALC203 and RT9123 and Rockchip
   SAI controllers
 
 * HD-audio:
 - Lots of cleanups of TAS2781 codec drivers
 - A new HD-audio control bound via ACPI for Nvidia
 - Support for Tegra264, Intel WCL, usual new codec quirks
 
 * USB-audio:

785cdec46e Core x86 updates for v6.16: 
Boot code changes:
 
  - A large series of changes to reorganize the x86 boot code into a better isolated
    and easier to maintain base of PIC early startup code in arch/x86/boot/startup/,
    by Ard Biesheuvel.
 
    Motivation & background:
 
 	| Since commit
 	|
 	|    c88d71508e ("x86/boot/64: Rewrite startup_64() in C")
 	|
 	| dated Jun 6 2017, we have been using C code on the boot path in a way
 	| that is not supported by the toolchain, i.e., to execute non-PIC C
 	| code from a mapping of memory that is different from the one provided
 	| to the linker. It should have been obvious at the time that this was a
 	| bad idea, given the need to sprinkle fixup_pointer() calls left and
 	| right to manipulate global variables (including non-pointer variables)
 	| without crashing.
 	|
 	| This C startup code has been expanding, and in particular, the SEV-SNP
 	| startup code has been expanding over the past couple of years, and
 	| grown many of these warts, where the C code needs to use special
 	| annotations or helpers to access global objects.
 
    This tree includes the first phase of this work-in-progress x86 boot code
    reorganization.

firmware: cs_dsp: Fix OOB memory read access in KUnit test (ctl cache) 
KASAN reported out of bounds access - cs_dsp_ctl_cache_init_multiple_offsets().
The code uses mock_coeff_template.length_bytes (4 bytes) for register value
allocations. But later, this length is set to 8 bytes which causes
test code failures.

As fix, just remove the lenght override, keeping the original value 4
for all operations.

13423063c7 arm64: kvm, smccc: Introduce and use API for getting hypervisor UUID 
The KVM/arm64 uses SMCCC to detect hypervisor presence. That code is
private, and it follows the SMCCC specification. Other existing and
emerging hypervisor guest implementations can and should use that
standard approach as well.

Factor out a common infrastructure that the guests can use, update KVM
to employ the new API. The central notion of the SMCCC method is the
UUID of the hypervisor, and the new API follows that.

No functional changes. Validated with a KVM/arm64 guest.

0f9a1739dd efi: zboot specific mechanism for embedding SBAT section 
SBAT is a mechanism which improves SecureBoot revocations of UEFI binaries
by introducing a generation-based technique. Compromised or vulnerable UEFI
binaries can be prevented from booting by bumping the minimal required
generation for the specific component in the bootloader. More information
on the SBAT can be obtained here:

https://github.com/rhboot/shim/blob/main/SBAT.md

Upstream Linux kernel does not currently participate in any way in SBAT as
there's no existing policy in how SBAT generation number should be
defined. Keep the status quo and provide a mechanism for distro vendors and
anyone else who signs their kernel for SecureBoot to include their own SBAT
data. This leaves the decision on the policy to the vendor. Basically, each
distro implementing SecureBoot today, will have an option to inject their
own SBAT data during kernel build and before it gets signed by their
SecureBoot CA. Different distro do not need to agree on the common SBAT
component names or generation numbers as each distro ships its own 'shim'
with their own 'vendor_cert'/'vendor_db'

Implement support for embedding SBAT data for architectures using
zboot (arm64, loongarch, riscv). Put '.sbat' section in between '.data' and
'.text' as the former also covers '.bss' and thus must be the last one.

Remove CONFIG_X86_5LEVEL and related #ifdeffery for it to make it more readable.

4e61c011b0 Arm SCMI updates for v6.16 
1. Quirk framework to handle buggy firmware
 
    With SCMI gaining broader adoption across arm64 platforms, it's
    increasingly important to address how we consistently manage out-of-spec
    SCMI firmware already deployed in the field. This change introduces a
    lightweight quirk framework built around static_keys, enabling developers to:
     - Define quirks and their match criteria, which can include:
        o A list of compatibles ({ comp, comp2, NULL })
        o Vendor ID / Sub-Vendor ID
        o Firmware implementation version ranges ([Min_Vers, Max_Vers])
 
    Matching proceeds from the most specific (longest match) to the least
    specific. NULL entries are treated as wildcards (i.e., match any value).
    This flexibility allows matching very specific combinations or just a
    general compatible string.
 
    The quirk code blocks/snippets implementing the workaround are placed near
    their intended usage and guarded by a static_key that's tied to the quirk.
    Once the SCMI core stack is initialized and retrieves platform info via the
    base protocol, any matching quirks will have their associated static_keys
    enabled.
 
 2. Quirk for Qualcomm X1E platforms
 
    On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
    SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
    yet it crashes when the driver attempts to fall back to standard messaging
    which is clearly out-of-spec behavior.
 
    To work around this, the new SCMI quirk framework is used to
    unconditionally enable FC initialization for this firmware version.
 
    In the future, once the fixed firmware version is identified, an upper
    version bound can be added to the quirk match criteria. Alternatively,
    matching can be further restricted using a SoC-specific compatible string
    if always enabling FC proves problematic elsewhere.
 
 3. Support for NXP i.MX LMM/CPU vendor protocol extensions
 
    The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
    and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
 
    These changes integrate the vendor-specific protocol extensions
    implementing the LMM and CPU protocols for the i.MX95, facilitating
    standardized communication between the operating system and the platform's
    firmware, which will be used by remoteproc drivers. The changes also
    include the necessary device tree bindings.
 
 4. Miscellaneous cleanups/changes
 
    These mainly include polling support in SCMI raw mode. The cleanups
    centralize error logging for SCMI device creation into a single helper
    function, consolidate the device matching logic into a single function, and
    ensure that devices must have a name for registration—removing support for
    unnamed devices when matching drivers and devices for probing. Transport
    devices are now excluded from bus matching, and the correct assignment of
    the parent device for the arm-scmi platform device is ensured in the
    transport drivers.
