From 96f95a17c1cfe65a002e525114d96616e91a8f2d Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 9 Jul 2018 13:09:56 -0700 Subject: [PATCH] Revert "arm64: Use aarch64elf and aarch64elfb emulation mode variants" This reverts commit 38fc4248677552ce35efc09902fdcb06b61d7ef9. Distributions such as Fedora and Debian do not package the ELF linker scripts with their toolchains, resulting in kernel build failures such as: | CHK include/generated/compile.h | LD [M] arch/arm64/crypto/sha512-ce.o | aarch64-linux-gnu-ld: cannot open linker script file ldscripts/aarch64elf.xr: No such file or directory | make[1]: *** [scripts/Makefile.build:530: arch/arm64/crypto/sha512-ce.o] Error 1 | make: *** [Makefile:1029: arch/arm64/crypto] Error 2 Revert back to the linux targets for now, adding a comment to the Makefile so we don't accidentally break this in the future.
