From 44621be4b563fbce32007ebfac91dfe8f5692743 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 8 Feb 2008 16:37:04 +1100 Subject: [PATCH] [POWERPC] Make cell IOMMU fixed mapping printk more useful Currently the cell IOMMU fixed mapping just printks that it's been setup, which is not particularly useful. Much more interesting is the address ranges for the different windows. This adds one line to dmesg on a blade.
