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.
