Thanks.

It looks like there is at least one more:

drivers/soc/fsl/qbman/qman.c: In function 'qman_init_fq':
drivers/soc/fsl/qbman/qman.c:1787:4: error: implicit declaration of function 'dma_map_single' [-Werror=implicit-function-declaration]
drivers/soc/fsl/qbman/qman.c:1788:21: error: 'DMA_TO_DEVICE' undeclared (first use in this function)
drivers/soc/fsl/qbman/qman.c:1789:4: error: implicit declaration of function 'dma_mapping_error' [-Werror=implicit-function-declaration]

This is from a powerpc orenet64_smp_defconfig build of today's
linux-next.
