Merge git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild
* git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild: (33 commits) xtensa: use DATA_DATA in xtensa powerpc: add missing DATA_DATA to powerpc cris: use DATA_DATA in cris kallsyms: remove usage of memmem and _GNU_SOURCE from scripts/kallsyms.c kbuild: use -fno-optimize-sibling-calls unconditionally kconfig: reset generated values only if Kconfig and .config agree. kbuild: fix the warning when running make tags kconfig: strip 'CONFIG_' automatically in kernel configuration search kbuild: use POSIX BRE in headers install target Whitelist references from __dbe_table to .init modpost white list pattern adjustment kbuild: do section mismatch check on full vmlinux kbuild: whitelist references from variables named _timer to .init.text kbuild: remove hardcoded _logo names from modpost kbuild: remove hardcoded apic_es7000 from modpost kbuild: warn about references from .init.text to .exit.text kbuild: consolidate section checks kbuild: refactor code in modpost to improve maintainability kbuild: ignore section mismatch warnings originating from .note section kbuild: .paravirtprobe section is obsolete, so modpost doesn't need to handle it ...
