Subject: svcrdma: fix compile warning on 32 bit platforms
From: Tom Tucker <tom@xxxxxxxxxxxxxxxxxxxxx>
The ib_sge is used to store both dma_addr_t and virtual addresses. This
causes a warning on 32b platforms when casting ptrs to the u64 addr field
of the ib_sge. There is work underway to reduce the memory footprint of
the WR context in 2.6.27 the time frame that will remove the overloading
of the ib_sge.addr field.
