You are not supposed to be using this function for such memory
allocations.

You don't.  If you look at the existing drivers and comments, you'll 
see it's
intended to only allocate small objects that are too inefficient to 
manage
with the usual Linux DMA allocation functions.  You must use the 
standard
Linux DMA for large allocations.  Read Documentation/DMA-API.txt, and
in particular the non-PCI functions.

Thanks.
