V6/V7 and the earlier V4/V5 are normally mutually exclusive, but we sometimes screw up the dependencies for some platform, in which case you can end up with a config that includes both and gives the above error. I'll have a look. I thought I'd fixed all the bugs we introduced in the merge window in yesterday's fixes branch. There is one known problem for mach-realview in this area, for which I have a fix. > > + /home/kisskb/slave/src/fs/dax.c: error: implicit declaration of function 'copy_user_page' [-Werror=implicit-function-declaration]: => 266:2 DAX support was merged with 'depends on !(ARM || MIPS || SPARC)', so I don't see how this could happen. > sh-randconfig > > > + /home/kisskb/slave/src/sound/soc/codecs/max98357a.c: error: implicit declaration of function 'devm_gpiod_get' [-Werror=implicit-function-declaration]: => 55:2 > > + /home/kisskb/slave/src/sound/soc/codecs/max98357a.c: error: implicit declaration of function 'gpiod_direction_output' [-Werror=implicit-function-declaration]: => 61:2 > > + /home/kisskb/slave/src/sound/soc/codecs/max98357a.c: error: implicit declaration of function 'gpiod_set_value' [-Werror=implicit-function-declaration]: => 30:3 Something wrong in arch/sh/include/asm/gpio.h? the codec is only selectable when gpiolib is enabled, but the consumer.h header apparently does not get included here. > s390-allyesconfig > s390-allmodconfig > parisc-allmodconfig > sh-allmodconfig > sh-allyesconfig > cris-allyesconfig > cris-allmodconfig > mips-allmodconfig > > > + error: asm9260_timer.c: undefined reference to `of_io_request_and_map': => .init.text+0x4014), .init.text+0x5c84) asm9260 is arm-specific, we probably need to refine the dependencies here to ensure that OF_ADDRESS is set. Need to think about what the best set of dependencies is. Arnd
