From e16b67f9a0ac6d9f89f680b7f3b439abfb1dac5e Mon Sep 17 00:00:00 2001 From: David Moore Date: Sun, 4 Feb 2007 13:39:40 -0500 Subject: Missing critical phys_to_virt in lib/swiotlb.c Missing critical phys_to_virt in lib/swiotlb.c Adds missing call to phys_to_virt() in the lib/swiotlb.c:swiotlb_sync_sg() function. Without this change, a kernel panic will always occur whenever a SWIOTLB bounce buffer from a scatter-gather list gets synced. Affected are especially Intel x86_64 machines with more than about 3 GB RAM.
