From b34eb53cdcb4f49fd31d78d0e385240820ed9063 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Fri, 28 Mar 2008 14:27:03 -0700 Subject: [IA64] make IOMMU respect the segment boundary limits IA64's IOMMU implementation allocates memory areas spanning LLD's segment boundary limit. It forces low level drivers to have a workaround to adjust scatter lists that the IOMMU builds. We are in the process of making all the IOMMUs respect the segment boundary limits to remove such work around in LLDs. This patch is for IA64's IOMMU.
