Commit 0f9a1739dd0e ("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.

Older versions of `ld` don't seem to support preprocessor directives in
linker scripts, e.g. on RHEL9's ld-2.35.2-63.el9 the build fails with:

 ld:./drivers/firmware/efi/libstub/zboot.lds:33: syntax error

We don't seem to need these '#ifdef', no empty .sbat section is created
when CONFIG_EFI_SBAT_FILE="":

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

   - Bug fix for the efi_test module

   - Log the physical address and size of the EFI memory map when
     failing to map it

   - A kerneldoc fix for the EFI stub code"

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

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

Tested on Loongson-3A5000 (enable GCC_PLUGIN_STACKLEAK and LKDTM):
 # echo STACKLEAK_ERASING &gt; /sys/kernel/debug/provoke-crash/DIRECT
 # dmesg

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.

  rust:
   - add drm core infrastructure rust abstractions
     (device/driver, ioctl, file, gem)

The pending status was not being passed to user space, leading to
false test alarms when using the pending status. This patch ensures
that the pending status is correctly updated and exposed to user space
when calling getwakeuptime, preventing incorrect handling of the pending
status.
