One of the requests during the first round of InfiniPath driver review was to compile the driver on a 32-bit platform. Our driver requires 64-bit MMIO operations (readq and writeq) that are not available on some arches, such as i386, and which can't be emulated safely in terms of 32-bit operations.
What's the correct way to get the driver to not compile on such platforms? Do I use CONFIG_64BIT as a proxy for "has readq and writeq"?
