From 9caee771b54ee4cfd38f1f31c3bdc22ebf6c9535 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 9 Jul 2018 16:01:27 -0700 Subject: [PATCH] Fix for arm64 compilation issue The short answer is that it looks like Fedora binutils doesn't quite work with this patch. The long answer might be more complicated but this gets things compiling. --- ...-aarch64elf-and-aarch64elfb-emulatio.patch | 54 +++++++++++++++++++ kernel.spec | 3 ++ 2 files changed, 57 insertions(+) create mode 100644 0001-Revert-arm64-Use-aarch64elf-and-aarch64elfb-emulatio.patch diff --git a/0001-Revert-arm64-Use-aarch64elf-and-aarch64elfb-emulatio.patch b/0001-Revert-arm64-Use-aarch64elf-and-aarch64elfb-emulatio.patch new file mode 100644 index 000000000..1ba1dd19f --- /dev/null +++ b/0001-Revert-arm64-Use-aarch64elf-and-aarch64elfb-emulatio.patch @@ -0,0 +1,54 @@ +From 4cf95d8ea33f6b4704229e64f8a215bc44bf2403 Mon Sep 17 00:00:00 2001 +From: Laura Abbott +Date: Mon, 9 Jul 2018 12:55:30 -0700 +Subject: [PATCH] Revert "arm64: Use aarch64elf and aarch64elfb emulation mode + variants" +To: Will Deacon +To: Paul Kocialkowski +To: Catalin Marinas +Cc: linux-arm-kernel@lists.infradead.org +Cc: linux-kernel@vger.kernel.org + +This reverts commit 38fc4248677552ce35efc09902fdcb06b61d7ef9. + +This breaks compilation with Fedora gcc-8 tool chains: + + 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 + +Fixes: 38fc42486775 ("arm64: Use aarch64elf and aarch64elfb emulation mode variants") +Signed-off-by: Laura Abbott +--- +A bit rushed and I'm still debugging but I wanted to send this out +before anyone else gets hit since it is -rc4.
