# 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.
