Pull EFI fixes from Ingo Molnar: "Various EFI fixes: - Fix the layering violation in the use of the EFI runtime services availability mask in users of the 'efivars' abstraction - Revert build fix for GCC v4.8 which is no longer supported - Clean up some x86 EFI stub details, some of which are borderline bugs that copy around garbage into padding fields - let's fix these out of caution. - Fix build issues while working on RISC-V support - Avoid --whole-archive when linking the stub on arm64" * tag 'efi-urgent-2020-07-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: efi: Revert "efi/x86: Fix build with gcc 4" efi/efivars: Expose RT service availability via efivars abstraction efi/libstub: Move the function prototypes to header file efi/libstub: Fix gcc error around __umoddi3 for 32 bit builds efi/libstub/arm64: link stub lib.a conditionally efi/x86: Only copy upto the end of setup_header efi/x86: Remove unused variables
