Subject: dma_pool_alloc restrict < 4GB address

Hi,

Is there anyway to restrict the returned bus address(dma address) from dma_poll_alloc to < 4GB ?
The function returns a dma address(of type dma_addr_t). Is there anyway I can ensure to restrict it to < 4B address.
I guess we can do that in pci_alloc_consistent as by default it returns 32bit address. 

with regards,
  Anil
