From 046e26a8ba10b8ceff822f8d91451ab6c1e08c4e Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 27 Aug 2008 04:54:04 -0700 Subject: sparc: Remove generic SBUS probing layer. The individual SBUS IOMMU arch code now sets the IOMMU information directly into the OF device objects. Signed-off-by: David S.
