From bebd9a455b2593ba6543b961bc82c43350c2d8d9 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Fri, 30 May 2008 10:03:26 +0200 Subject: [PATCH] [S390] s390 types: make dma_addr_t 64 bit capable virtio tests with guests larger than 4 GB revealed that the dma_addr_t definition for s390 did not make it into the 64bit world. This patch changes the definition on s390 to have an u64 on 64bit and u32 on 32bit systems.
