+# Works like allyesconfig. This is a bit more involved than allnoconfig as we
+# need to handle choices in two different modes:
+#
+# "y": One symbol is "y", the rest are "n".
+# "m": Any number of symbols are "m", the rest are "n".
+#
+# Only tristate choices can be in "m" mode. It is safe since the code for two
+# conflicting options will appear as separate modules instead of simultaneously
+# in the kernel.
+#
+# If a choice can be in "y" mode, it will be. If it can only be in "m" mode
+# (due to dependencies), then all the options will be set to "m".
+#
+# The looping is in case setting one symbol to "y" (or "m") allows the value of
+# other symbols to be raised.
