[openib-general] IB/ipath - Implement new verbs DMA mapping functions

[James Lentini]

Ralph,

Could you add documentation to Documentation/infiniband/ explainin 
when a ULP needs to use the new verbs DMA mapping functions (what 
structures/function parameters must be specified using this API)? 

Did you consider creating a new type, ib_dma_addr_t, and using this 
type for the verb structure members/function parameters that require 
it?
