I thought that it was going to be the default for a lot of distros that would need to run on UEFI systems. > menu "Userspace binary formats" > diff --git a/arch/arm64/kernel/Makefile b/arch/arm64/kernel/Makefile > index 5ba2fd4..1c52b84 100644 > --- a/arch/arm64/kernel/Makefile > +++ b/arch/arm64/kernel/Makefile > @@ -4,6 +4,8 @@ > > CPPFLAGS_vmlinux.lds := -DTEXT_OFFSET=$(TEXT_OFFSET) > AFLAGS_head.o := -DTEXT_OFFSET=$(TEXT_OFFSET) > +CFLAGS_efi-stub.o := -DTEXT_OFFSET=$(TEXT_OFFSET) \ > + -I$(src)/../../../scripts/dtc/libfdt Hmm, this is pretty ugly.
