[PATCH v3 0/4] make io{read|write}64 more globally usable

From: Logan Gunthorpe

Hi,

Here's my third attempt. This time we add functions to io-64-nonatomic-*
which call io{read|write}32 twice so that the pio is done correctly.

I've also included a patch that adds these functions to the generic iomap
library so that readq/writeq can be used while still splitting pio
operations (when appropriate).

Thanks,

Logan
