   The DMA_ALIGN attribute doesn't work, on some systems the PCI
   cacheline size is determined at boot time not compile time.

Another note, it could be per-PCI controller what this cacheline size
is. We'll need to pass in a pdev to the alignment interfaces to
do this correctly.

So none of this can be done at compile time folks.
