    vkernel64 - Add missing bits from later kernel work in the main tree
    
    * Add missing virtual kernel intercept in 64-bit real kernel trap.c code.
    
    * Add td_ucred caching to userenter() in vkernel64 trap.c code.
    
    * Set PG_RW, PG_U, PG_V in pcb_cr3.  It is unclear whether these
      are necessary.
    
    * Remove debugging.
