Linus Torvalds 06e1a81c48 A healthy mix of EFI contributions this time:
- Performance tweaks for efifb earlycon by Andy
 
 - Preparatory refactoring and cleanup work in the efivar layer by Johan,
   which is needed to accommodate the Snapdragon arm64 laptops that
   expose their EFI variable store via a TEE secure world API.
 
 - 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 contributed by
   Evgeniy and wire it up in the EFI zboot code. 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 by 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 by Darrell.
