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
