Message-ID: <1227008661-1609-1-git-send-email-joerg.roedel@amd.com> Date: Tue, 18 Nov 2008 12:44:21 +0100 From: Joerg Roedel <joerg.roedel@....com> To: Ingo Molnar <mingo@...hat.com>, Thomas Gleixner <tglx@...utronix.de> CC: linux-kernel@...r.kernel.org, iommu@...ts.linux-foundation.org, Joerg Roedel <joerg.roedel@....com>, hawk@...-linux.org, stable@...nel.org Subject: [PATCH] x86: always select SWIOTLB on x86_64 Impact: fixes korg bugzilla 11980 A kernel for a 64bit x86 system should always contain the swiotlb code in case it is booted on a machine without any hardware IOMMU supported by the kernel and more than 4GB of RAM. This patch changes Kconfig to always compile swiotlb into the kernel for x86_64.
