I guess, I need split the 'big' patch into pieces, and each send to its' related mailing list, so let it not like a spam. And the schedule may like: - Firstly, send patch for "init/Kconfig" to add CPU_*_ENDIAN. If pass checking (hope it can be passed checking), then - Send each related patch to each related architectures which already knew their ENDIAN attributes in config time (24 patches, I guess), then - Make patch for Kbuild to support __BUILDING_TIME_BIG_ENDIAN__, and pass checking (hope I can finish), then - Finish left architectures which need __BUILDING_TIME_BIG_ENDIAN__ (4 patches, I guess). Welcome any ideas, suggestions, or completions. And if no additional reply, I shall not send any additional information any more to avoid spam to other members. Thanks.
