IB/srp: Fix FMR mapping for 32-bit kernels and addresses above 4G
struct srp_device.fmr_page_mask was unsigned long, which means that the top part of addresses above 4G was being chopped off on 32-bit architectures. Of course nothing good happens when data from SRP targets is DMAed to the wrong place. Fix this by changing fmr_page_mask to u64, to match the addresses actually used by IB devices. Thanks to Brian Cain <Brian.Cain@ge.com> and David McMillen <davem@systemfabricworks.com> for help diagnosing the bug and testing the fix. Signed-off-by: Roland Dreier <rolandd@cisco.com>
