Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull EFI updates from Ingo Molnar:
 "The main changes in this development cycle were:

   - Implement EFI dev path parser and other changes to fully support
     thunderbolt devices on Apple Macbooks (Lukas Wunner)

   - Add RNG seeding via the EFI stub, on ARM/arm64 (Ard Biesheuvel)

   - Expose EFI framebuffer configuration to user-space, to improve
     tooling (Peter Jones)

   - Misc fixes and cleanups (Ivan Hu, Wei Yongjun, Yisheng Xie, Dan
     Carpenter, Roy Franz)"
