From: Hanna Hawa <hannah@xxxxxxxxxxx> >> drivers/dma/mv_xor_v2.c:647:36: sparse: constant 0xFFFF00000000 is so big it is long include/linux/device.h:678:13: sparse: undefined identifier '__builtin_mul_overflow' include/linux/device.h:678:13: sparse: call with no type! Use lower_32_bits and upper_32_bits to set the hw_desq address, instead of using constant.
