Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kbuild updates from Michal Marek: "Here is the first round of kbuild changes for v4.1-rc1: - kallsyms fix for ARM and cleanup - make dep(end) removed (developers have no sense of nostalgia these days...) - include Makefiles by relative path - stop useless rebuilds of asm-offsets.h and bounds.h" * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: Kbuild: kallsyms: drop special handling of pre-3.0 GCC symbols Kbuild: kallsyms: ignore veneers emitted by the ARM linker kbuild: ia64: use $(src)/Makefile.gate rather than particular path kbuild: include $(src)/Makefile rather than $(obj)/Makefile kbuild: use relative path more to include Makefile kbuild: use relative path to include Makefile kbuild: do not add $(bounds-file) and $(offsets-file) to targets kbuild: remove warning about "make depend" kbuild: Don't reset timestamps in include/generated if not needed
