Merge git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild
* git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild: (40 commits) kbuild: introduce ccflags-y, asflags-y and ldflags-y kbuild: enable 'make CPPFLAGS=...' to add additional options to CPP kbuild: enable use of AFLAGS and CFLAGS on commandline kbuild: enable 'make AFLAGS=...' to add additional options to AS kbuild: fix AFLAGS use in h8300 and m68knommu kbuild: check for wrong use of CFLAGS kbuild: enable 'make CFLAGS=...' to add additional options to CC kbuild: fix up CFLAGS usage kbuild: make modpost detect unterminated device id lists kbuild: call export_report from the Makefile kbuild: move Kai Germaschewski to CREDITS kconfig/menuconfig: distinguish between selected-by-another options and comments kconfig: tristate choices with mixed tristate and boolean values include/linux/Kbuild: remove duplicate entries kbuild: kill backward compatibility checks kbuild: kill EXTRA_ARFLAGS kbuild: fix documentation in makefiles.txt kbuild: call make once for all targets when O=.. is used kbuild: pass -g to assembler under CONFIG_DEBUG_INFO kbuild: update _shipped files for kconfig syntax cleanup ... Fix up conflicts in arch/um/sys-{x86_64,i386}/Makefile manually.
