Author: ian Date: Sat Jul 26 18:14:16 2014 New Revision: 269135 URL: http://svnweb.freebsd.org/changeset/base/269135 Log: Remove completely bogus alignment check -- it's the physical address that needs to be aligned, not the virtual, and it doesn't seem worth the cost of a vtophys() call just to see if kmem_alloc_contig() works properly.
