No.. these drivers dont call DMA mapping api's.. thats the proble

What is the problem? You can't allocate mappings <16MB?
floppy doesn't use the DMA mapping API :)
that's the problem

Floppy disk drivers dont work well with DMA remapping. Its possible to
extend the current use for x86_64, but the gain is very little. If someone
feels compelled to clean this up, its up for grabs. Since these use 16M, we
just provide a unity map for the ISA bridge device.

Floppy disk drivers dont work well with DMA remapping. Its possible to
extend the current use for x86_64, but the gain is very little. If someone
