Hi,
The same .config file, also report the compiling error below:
drivers/i2c/busses/i2c-ocores.c:81:2: error: implicit declaration of function ‘iowrite8’ [-Werror=implicit-function-declaration]
drivers/i2c/busses/i2c-ocores.c:86:2: error: implicit declaration of function ‘iowrite16’ [-Werror=implicit-function-declaration]
drivers/i2c/busses/i2c-ocores.c:91:2: error: implicit declaration of function ‘iowrite32’ [-Werror=implicit-function-declaration]
drivers/i2c/busses/i2c-ocores.c:96:2: error: implicit declaration of function ‘ioread8’ [-Werror=implicit-function-declaration]
drivers/i2c/busses/i2c-ocores.c:101:2: error: implicit declaration of function ‘ioread16’ [-Werror=implicit-function-declaration]
drivers/i2c/busses/i2c-ocores.c:106:2: error: implicit declaration of function ‘ioread32’ [-Werror=implicit-function-declaration]
Excuse me, I am not quite familiar with the related hardware and m68k,
I guess under m68k architecture, we need not this drivers, is it correct ?
That would be correct, yes. Perhaps add appropriate dependencies in
drivers/i2c/Kconfig to allow building I2C drivers
only on hardware that supports it?
(Joking - some fallout would be expected when using make randconfig)
Cheers,
Michael
Thanks.

Define 'VM_DATA_DEFAULT_FLAGS' when 'NOMMU' to pass compiling.
So move it from "include/asm/page_mm.h to "include/asm/page.h"
The related make:
make ARCH=m68k randconfig
make ARCH=m68k menuconfig
choose cross compiler
disable MMU support
make ARCH=m68k V=1 EXTRA_CFLAGS=-W
The related error:
security/selinux/hooks.c: In function �selinux_init�:
security/selinux/hooks.c:5821:21: error: �VM_DATA_DEFAULT_FLAGS� undeclared (first use in this function)
(the attachment is the related .config file)
