RDMA/siw: Fix 64/32bit pointer inconsistency
Fixes improper casting between addresses and unsigned types. Changes siw_pbl_get_buffer() function to return appropriate dma_addr_t, and not u64. Also fixes debug prints. Now any potentially kernel private pointers are printed formatted as '%pK', to allow keeping that information secret. Fixes: d941bfe500be ("RDMA/siw: Change CQ flags from 64->32 bits") Fixes: b0fff7317bb4 ("rdma/siw: completion queue methods") Fixes: 8b6a361b8c48 ("rdma/siw: receive path") Fixes: b9be6f18cf9e ("rdma/siw: transmit path") Fixes: f29dd55b0236 ("rdma/siw: queue pair methods") Fixes: 2251334dcac9 ("rdma/siw: application buffer management") Fixes: 303ae1cdfdf7 ("rdma/siw: application interface") Fixes: 6c52fdc244b5 ("rdma/siw: connection management") Fixes: a531975279f3 ("rdma/siw: main include file") Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Reported-by: Jason Gunthorpe <jgg@ziepe.ca> Reported-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Bernard Metzler <bmt@zurich.ibm.com> Link: https://lore.kernel.org/r/20190822173738.26817-1-bmt@zurich.ibm.com Signed-off-by: Doug Ledford <dledford@redhat.com>
