Date: Tue, 06 Oct 2015 23:47:44 +0200 From: Arnd Bergmann <arnd@...db.de> To: netdev@...r.kernel.org Cc: davem@...emloft.net, Jiri Pirko <jiri@...lanox.com>, Ido Schimmel <idosch@...lanox.com>, linux-kernel@...r.kernel.org, Elad Raz <eladr@...lanox.com>, Scott Feldman <sfeldma@...il.com>, linux-arm-kernel@...ts.infradead.org Subject: [PATCH] mlxsw: fix warnings for big-endian 32-bit dma_addr_t The recently added mlxsw driver produces warnings in ARM allmodconfig: drivers/net/ethernet/mellanox/mlxsw/pci.c: In function 'mlxsw_pci_cmd_exec': drivers/net/ethernet/mellanox/mlxsw/pci.c:1585:59: warning: right shift count >= width of type [-Wshift-count-overflow] linux/byteorder/big_endian.h:38:51: note: in definition of macro '__cpu_to_be32' drivers/net/ethernet/mellanox/mlxsw/pci.c:76:2: note: in expansion of macro 'iowrite32be' This changes the type of the local variable to u64, which gets rid of the warning and seems nicer than adding #ifdefs.
