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
