Merge tag 'efi-next-for-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
- Fix a syzbot reported issue in efivarfs where concurrent accesses to
the file system resulted in list corruption
- Add support for accessing EFI variables via the TEE subsystem (and a
trusted application in the secure world) instead of via EFI runtime
firmware running in the OS's execution context
- Avoid linker tricks to discover the image base on LoongArch
