    Pull EFI updates from Ard Biesheuvel:
     "A healthy mix of EFI contributions this time:
    
       - Performance tweaks for efifb earlycon (Andy)
    
       - Preparatory refactoring and cleanup work in the efivar layer, which
         is needed to accommodate the Snapdragon arm64 laptops that expose
         their EFI variable store via a TEE secure world API (Johan)
    
       - Enhancements to the EFI memory map handling so that Xen dom0 can
         safely access EFI configuration tables (Demi Marie)
    
       - Wire up the newly introduced IBT/BTI flag in the EFI memory
         attributes table, so that firmware that is generated with ENDBR/BTI
         landing pads will be mapped with enforcement enabled
    
       - Clean up how we check and print the EFI revision exposed by the
         firmware
    
       - Incorporate EFI memory attributes protocol definition and wire it
         up in the EFI zboot code (Evgeniy)
    
         This ensures that these images can execute under new and stricter
         rules regarding the default memory permissions for EFI page
         allocations (More work is in progress here)
    
       - CPER header cleanup (Dan Williams)
    
       - Use a raw spinlock to protect the EFI runtime services stack on
         arm64 to ensure the correct semantics under -rt (Pierre)
    
       - EFI framebuffer quirk for Lenovo Ideapad (Darrell)"
