ppc6xx_defconfig fails building sfc.ko module, complaining about the lack of _umoddi3 symbol.
This is due to the following test if (EFX_MIN_DMAQ_SIZE % reader->value) { Because reader->value is u64. As EFX_MIN_DMAQ_SIZE value is 512, reader->value is obviously small enough for an u32 calculation, so cast it as (u32) for the test, to avoid the need for _umoddi3.
