[Mark Craske]

Background information
----------------------
These 2 commits were originally developed and validated on an ARM i.MX6 based
commercial project running a highly modified 3.14 Linux kernel.
The commits were needed to amend dma_mmap_from_coherent() to deal correctly
with mappings of less than one page, and to improve latency on SMP systems
where large DMA buffers are used.

The commits have been forward-ported to driver-core repo driver-core-next
branch HEAD (6ee6d1c carl9170: fix debugfs crashes)

Commit details
--------------
This patchset fixes a couple of problems with dma-coherent seen
on a commercial i.MX6 based system.

Note: Testing has only been done on an ARM i.MX6 based platform.
