Current iw_cxgb3 code adds PBL memory to the driver's gen_pool in 2 MB chunks. This limits the largest single allocation that can be done to the same size, which means that with 4 KB pages, each of which takes 8 bytes of PBL memory, the largest memory region that can be allocated is 1 GB (256K PBL entries * 4 KB/entry). Remove this limit by adding all the PBL memory in a single gen_pool chunk, if possible. Add code that falls back to smaller chunks if gen_pool_add() fails, which can happen if there is not sufficient contiguous lowmem for the internal gen_pool bitmap.
