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 ^ permalink raw reply [flat|nested] 6+ messages in thread

I think it's an bad select, for which a patch has been available since about 2 weeks.

I misread your email and thought this was still under arm-randconfig. I checked the other architectures, and found that the same is missing on ARC, so we should add both: diff --git a/fs/Kconfig b/fs/Kconfig index ec35851e5b71..a24d496787d6 100644 --- a/fs/Kconfig +++ b/fs/Kconfig @@ -36,7 +36,7 @@ source "fs/nilfs2/Kconfig" config FS_DAX bool "Direct Access (DAX) support" depends on MMU - depends on !(ARM || MIPS || SPARC) + depends on !(ARC || ARM || MIPS || SH || SPARC) help Direct Access (DAX) can be used on memory-backed block devices. If the block device supports DAX and the filesystem supports DAX, It's also not implemented on c6x and blackfin, but both of them have MMU=n, so they are already excluded. > >> 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. > > I think it's an bad select, for which a patch has been available since > about 2 weeks. Ah, right. I was looking at linux-next, which has the fix, so I did not see the problem at first. Arnd ^ permalink raw reply related [flat|nested] 6+ messages in thread
