From 4979d18fe105297f8f065743f31f8f735da8df2d Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Wed, 12 Jan 2011 09:50:36 -0800 Subject: mlx4_{core, ib, en}: Fix driver when sizeof (phys_addr_t) > sizeof (long) Some systems have PCI addresses that don't fit in unsigned long (eg some 32-bit PowerPC 440 systems have 36-bit bus addresses). Fix up mlx4 drivers by using phys_addr_t where appropriate, so we don't truncate any PCI resource addresses before ioremapping them.
