Linus Torvalds fc4c9f4504 EFI updates for v6.2:
- Refactor the zboot code so that it incorporates all the EFI stub
   logic, rather than calling the decompressed kernel as a EFI app.
 - Add support for initrd= command line option to x86 mixed mode.
 - Allow initrd= to be used with arbitrary EFI accessible file systems
   instead of just the one the kernel itself was loaded from.
 - Move some x86-only handling and manipulation of the EFI memory map
   into arch/x86, as it is not used anywhere else.
 - More flexible handling of any random seeds provided by the boot
   environment (i.e., systemd-boot) so that it becomes available much
   earlier during the boot.
 - Allow improved arch-agnostic EFI support in loaders, by setting a
   uniform baseline of supported features, and adding a generic magic
   number to the DOS/PE header. This should allow loaders such as GRUB or
   systemd-boot to reduce the amount of arch-specific handling
   substantially.
 - (arm64) Run EFI runtime services from a dedicated stack, and use it to
   recover from synchronous exceptions that might occur in the firmware
   code.
 - (arm64) Ensure that we don't allocate memory outside of the 48-bit
   addressable physical range.
 - Make EFI pstore record size configurable
 - Add support for decoding CXL specific CPER records

Pull EFI updates from Ard Biesheuvel:
 "Another fairly sizable pull request, by EFI subsystem standards.

  Most of the work was done by me, some of it in collaboration with the
  distro and bootloader folks (GRUB, systemd-boot), where the main focus
  has been on removing pointless per-arch differences in the way EFI
  boots a Linux kernel.

   - Refactor the zboot code so that it incorporates all the EFI stub
     logic, rather than calling the decompressed kernel as a EFI app.

   - Add support for initrd= command line option to x86 mixed mode.

   - Allow initrd= to be used with arbitrary EFI accessible file systems
     instead of just the one the kernel itself was loaded from.

   - Move some x86-only handling and manipulation of the EFI memory map
     into arch/x86, as it is not used anywhere else.

   - More flexible handling of any random seeds provided by the boot
     environment (i.e., systemd-boot) so that it becomes available much
     earlier during the boot.

   - Allow improved arch-agnostic EFI support in loaders, by setting a
     uniform baseline of supported features, and adding a generic magic
     number to the DOS/PE header. This should allow loaders such as GRUB
     or systemd-boot to reduce the amount of arch-specific handling

     firmware code.

     addressable physical range.

   - Make EFI pstore record size configurable

   - Add support for decoding CXL specific CPER records"
