Do you use mainline code only, or do you have home-made code ?

memcpy() is not supposed to be used on non-cacheable memory.
memcpy_toio() is the function to use when copying to non-cacheble area.

When I submitted the patch, I looked for erroneous use of memcpy() and 
memset().
I found one wrong use of memset() that I changed to memset_io() but I 
didn't find any misuse of memcpy().
But I may have missed one.
