[PATCH] powerpc: 64k pages vs. U3 iommu
That DART (U3 iommu) code didn't properly scale the number of entries when using !4k pages. That caused crashes when booting G5s with more than 2Gb of RAM. This fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
