    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
         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"
