Hi all, After merging the akpm-current tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from usr/include/linux/byteorder/big_endian.hdrtest.c:1: ./usr/include/linux/byteorder/big_endian.h:6:2: error: #error "Unsupported endianness, check your toolchain" #error "Unsupported endianness, check your toolchain" ^~~~~ Caused by commit 1ac94caaee11 ("byteorder: sanity check toolchain vs kernel endianness") Presumably exposed by commit b91976b7c0e3 ("kbuild: compile-test UAPI headers to ensure they are self-contained") from the kbuild tree. I have reverted 1ac94caaee11 (and its following fixup) for today. -- Cheers, Stephen Rothwell
