[PATCH] sun4: fix sbus_setup_iommu()

iommu_init() and iounit_init() are never called for sun4, but that's not enough - these calls should be ifdefed out since the functions in question simply do not exist for CONFIG_SUN4 kernel. Signed-off-by: Al Viro <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
