New Revision: 206169
URL: http://svn.freebsd.org/changeset/base/206169

Log:
  o) If we double the number of PTEs in a page table page, we have to double the
     segment size.  If we double the amount of memory each PTE covers we need to
     double the segment size yet again.  Increase the segment shift by 2 since we
     doubled the page size (and further, define it in terms of shift first and
     foremost.)
