This series adds __ioread32_copy() and uses it in two places. Andrew is on Cc in case this should go through the -mm tree. Otherwise the target of this patch series is SMD, so I've sent it to Andy. Note this patch series relies on a previous patch on the list that changes the readl() to __raw_readl() in the smd driver[1].
