Merge branch 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kconfig updates from Michal Marek: - dependency solver fix for make defconfig - randconfig fixes, one of which had to be reverted again - more user-friendly sorting of search results - hex and range keywords support longs - fix for [mn]conf not to rely on particular behavior of the LINES and COLS variables - cleanup of magic constants in kconfig/lxdialog - [mn]conf formatting fixes - fix for scripts/config's help text in out-of-tree usage (under a different name) * 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kconfig: allow "hex" and "range" to support longs Revert "kconfig: fix randomising choice entries in presence of KCONFIG_ALLCONFIG" kconfig: fix randomising choice entries in presence of KCONFIG_ALLCONFIG kconfig: loop as long as we changed some symbols in randconfig kconfig/[mn]conf: make it explicit in the search box that a regexp is possible kconfig: sort found symbols by relevance kconfig/conf: print the seed used to initialise the RNG for randconfig kconfig/conf: accept a base-16 seed for randconfig kconfig/conf: fix randconfig setting multiple symbols in a choice scripts/config: replace hard-coded script name by a dynamic value mconf/nconf: mark empty menus/menuconfigs different from non-empty ones nconf: use function calls instead of ncurses' variables LINES and COLS mconf: use function calls instead of ncurses' variables LINES and COLS kconfig/lxdialog: handle newline characters in print_autowrap() kconfig/lxdialog: Use new mininimum resize definitions in conf_choice() kconfig/lxdialog: Add definitions for mininimum (re)size values kconfig: Fix defconfig when one choice menu selects options that another choice menu depends on
