Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kbuild changes from Michal Marek: - fix make -s detection with make-4.0 - fix for scripts/setlocalversion when the kernel repository is a submodule - do not hardcode ';' in macros that expand to assembler code, as some architectures' assemblers use a different character for newline - Fix passing --gdwarf-2 to the assembler * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: frv: Remove redundant debugging info flag mn10300: Remove redundant debugging info flag kbuild: Fix debugging info generation for .S files arch: use ASM_NL instead of ';' for assembler new line character in the macro kbuild: Fix silent builds with make-4 Fix detectition of kernel git repository in setlocalversion script [take #2]
