2019-12-30gcc-9: silence 'address-of-packed-member' warningLinus Torvalds1-1/+1
commit 6f303d60534c46aa1a239f29c321f95c83dda748 upstream. We already did this for clang, but now gcc has that warning too. Yes, yes, the address may be unaligned. And that's kind of the point.

commit 238bcbc4e07fad2fff99c5b157d0c37ccd4d093c upstream. Collect basic Clang options such as --target, --prefix, --gcc-toolchain, -no-integrated-as into a single variable CLANG_FLAGS so that it can be easily reused in other parts of Makefile.

2019-01-13kbuild: add -no-integrated-as Clang option unconditionallyMasahiro Yamada1-2/+2
commit dbe27a002ef8573168cb64e181458ea23a74e2b6 upstream. We are still a way off the Clang's integrated assembler support for the kernel. Hence, -no-integrated-as is mandatory to build the kernel with Clang. If you had an ancient version of Clang that does not recognize this option, you would not be able to compile the kernel anyway.

2019-01-13kbuild: fix false positive warning/error about missing libelfMasahiro Yamada1-5/+8
[ Upstream commit ef7cfd00b2caf6edeb7f169682b64be2d0a798cf ] For the same reason as commit 25896d073d8a ("x86/build: Fix compiler support check for CONFIG_RETPOLINE"), you cannot put this $(error ...) into the parse stage of the top Makefile. Perhaps I'd propose a more sophisticated solution later, but this is the best I can do for now.

2018-12-01kbuild: allow to use GCC toolchain not in Clang search pathStefan Agner1-3/+5
commit ef8c4ed9db80261f397f0c0bf723684601ae3b52 upstream. When using a GCC cross toolchain which is not in a compiled in Clang search path, Clang reverts to the system assembler and linker. This leads to assembler or linker errors, depending on which tool is first used for a given architecture. It seems that Clang is not searching $PATH for a matching assembler or linker. Make sure that Clang picks up the correct assembler or linker by passing the cross compilers bin directory as search path. This allows to use Clang provided by distributions with GCC toolchains not in /usr/bin.

2018-09-05x86/vdso: Fix vDSO build if a retpoline is emittedAndy Lutomirski1-0/+4
commit 2e549b2ee0e358bc758480e716b881f9cabedb6a upstream. Currently, if the vDSO ends up containing an indirect branch or call, GCC will emit the "external thunk" style of retpoline, and it will fail to link. Fix it by building the vDSO with inline retpoline thunks. I haven't seen any reports of this triggering on an unpatched kernel.
