Author: alc Date: Sun Feb 21 22:23:13 2010 New Revision: 204181 URL: http://svn.freebsd.org/changeset/base/204181 Log: Align the start of the clean submap to a superpage boundary. Although no superpage mappings are created within the clean submap, aligning the start of the clean submap helps to prevent interference with kmem_alloc()'s use of superpages.
