Merge branch 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

Pull kconfig updates from Michal Marek:
 "This is the kconfig part of kbuild for v3.12-rc1:
   - post-3.11 search code fixes and micro-optimizations
   - CONFIG_MODULES is no longer a special case; this is needed to
     eventually fix the bug that using KCONFIG_ALLCONFIG breaks
     allmodconfig
   - long long is used to store hex and int values
   - make silentoldconfig no longer warns when a symbol changes from
     tristate to bool (it's a job for make oldconfig)
   - scripts/diffconfig updated to work with newer Pythons
   - scripts/config does not rely on GNU sed extensions"

   - "modules"
     This declares the symbol to be used as the MODULES symbol, which
     enables the third modular state for all config symbols.
+    At most one symbol may have the "modules" option set.
