[PATCH v3 0/4] Add __ioread32_copy() and use it

[Stephen Boyd <sboyd@codeaurora.org>]

The SMD driver is reading and writing chunks of data to iomem,
and there's an __iowrite32_copy() function for the writing part, but
no __ioread32_copy() function for the reading part. This series
adds __ioread32_copy() and uses it in two places.

This is a respin with some small fixes found with soaking in -next.

Andrew, the patches should apply cleanly to linux-next, so I hope
you can pick them up directly now, instead of the previous plan where
they would go through Andy's tree.

Changes from v2:
 * Make bcm patch actually compile
 * Add new patch for frv to avoid warnings
