Hi all, After merging the kbuild tree, today's linux-next build (powerpc ppc64_defconfig) produced these warnings: Presumably introduced by commit 1267f9d3047d ("kbuild: add $(BASH) to run scripts with bash-extension") and presumably arch/powerpc/tools/unrel_branch_check.sh (which has no #! line) is a bash script. Yeah, is uses '((' and '))'. -- Cheers, Stephen Rothwell
