#     kconfig.h: explain IS_MODULE(), IS_ENABLED()
#     
#     Extend IS_MODULE() and IS_ENABLED comments to explain why one might use
#     "#if IS_ENABLED(CONFIG_FOO)" instead of "#ifdef CONFIG_FOO".
#     
#     To wit, "#ifdef CONFIG_FOO" is true only for CONFIG_FOO=y, while
#     "#if IS_ENABLED(CONFIG_FOO)" is true for both CONFIG_FOO=y and
#     CONFIG_FOO=m.
#     
#     This is because "CONFIG_FOO=m" in .config does not result in "CONFIG_FOO"
#     being defined.  The actual definitions are in autoconf.h, where:
#     
#       CONFIG_FOO=y   results in   #define CONFIG_FOO 1
#       CONFIG_FOO=m   results in   #define CONFIG_FOO_MODULE 1
