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
