Merge git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild
* git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild: (79 commits) Remove references to "make dep" kconfig: document use of HAVE_* Introduce new section reference annotations tags: __ref, __refdata, __refconst kbuild: warn about ld added unique sections kbuild: add verbose option to Section mismatch reporting in modpost kconfig: tristate choices with mixed tristate and boolean values asm-generic/vmlix.lds.h: simplify __mem{init,exit}* dependencies remove __attribute_used__ kbuild: support ARCH=x86 in buildtar kconfig: remove "enable" kbuild: simplified warning report in modpost kbuild: introduce a few helpers in modpost kbuild: use simpler section mismatch warnings in modpost kbuild: link vmlinux.o before kallsyms passes kbuild: introduce new option to enhance section mismatch analysis Use separate sections for __dev/__cpu/__mem code/data compiler.h: introduce __section() all archs: consolidate init and exit sections in vmlinux.lds.h kbuild: check section names consistently in modpost kbuild: introduce blacklisting in modpost ...
