Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kbuild updates from Michal Marek: - Make <modname>-m in makefiles work like <modname>-y and fix the fallout - Minor genksyms fix - Fix race with make -j install modules_install - Move -Wsign-compare from make W=1 to W=2 - Other minor fixes * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild: Demote 'sign-compare' warning to W=2 Makefile: revert "Makefile: Document ability to make file.lst and file.S" partially kbuild: Do not run modules_install and install in paralel genksyms: Handle string literals with spaces in reference files fixdep: constify strrcmp arguments ath10k: Fix build with CONFIG_THERMAL=m Revert "drm: Hack around CONFIG_AGP=m build failures" kbuild: Allow to specify composite modules with modname-m staging/ad7606: Actually build the interface modules
