Hi Russell,

Kernel build failed on arm-allnoconfig:

include/linux/math64.h:55:15: error: '__LINUX_ARM_ARCH__' undeclared (first use in this function)
arch/arm/include/asm/glue-cache.h:129:2: error: #error Unknown cache maintenance model
arch/arm/include/asm/glue-df.h:99:2: error: #error Unknown data abort handler type
arch/arm/include/asm/glue-pf.h:54:2: error: #error Unknown prefetch abort handler type

Do you think this allnoconfig test meaningful at all?

Thanks,
Fengguang
