Roland Dreier 532c3b5817 IB/mthca: Fix mthca_write_mtt() on HCAs with hidden memory ... Commit b2875d4c ("IB/mthca: Always fill MTTs from CPU") causes a crash in mthca_write_mtt() with non-memfree HCAs that have their memory hidden (that is, have only two PCI BARs instead of having a third BAR that allows access to the RAM attached to the HCA) on 64-bit architectures. This is because the commit just before, c20e20ab ("IB/mthca: Merge MR and FMR space on 64-bit systems") makes dev->mr_table.fmr_mtt_buddy equal to &dev->mr_table.mtt_buddy and hence mthca_write_mtt() tries to write directly into the HCA's MTT table. However, since that table is in the HCA's memory, this is impossible without the PCI BAR that gives access to that memory. This causes a crash because mthca_tavor_write_mtt_seg() basically tries to dereference some offset of a NULL pointer. Fix this by adding a test of MTHCA_FLAG_FMR in mthca_write_mtt() so that we always use the WRITE_MTT firmware command rather than writing directly if FMRs are not enabled.
