  > wt(4) was removed a while ago, so don't support booting off it anoymore.

arch/i386/i386

  ~ pmap.c                                

  > According to Intel errata:
  > "AI91 - Update of attribute bits on page directories without immediate
  > tlb shootdown may cause unexpected processor behavior.".
  > When we're allocating kernel page tables, we use the generic page table
  > allocation function that sets PG_u then we immediately remove the PG_u.
  > This might not be enough, because the PDE can get preloaded into the
  > translation cache before we clear the PG_u. So even without the errata,
  > this could cause us horrible trouble.
  > Instead of first entering the PDE with PG_u and then removing it for
  > kernel page tables, just enter it with the right bits every time.
  > tom@ ok (art@)
