Pull kconfig updates from Michal Marek: "Just two kconfig commits this time: - kconfig Makefile fix for make 3.80 - Fix calculating symbols so that KCONFIG_ALLCONFIG=... does not disable CONFIG_MODULES silently" * 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: unbreak allmodconfig KCONFIG_ALLCONFIG=... scripts/kconfig: allow building with make 3.80 again
