                * i386/configfrag.ac: Add --enable-pae option, which defines 
PAE.

macros.
                * i386/i386/locore.S [PAE] (copyout_retry): Use page directory 
pointer
                bits.
                * i386/i386at/model_dep.c [PAE] (i386at_init): Set second 
initial 2MB
                page.  Enable PAE bit.  Set cr3 to page directory pointer table 
instead

                * i386/intel/pmap.c [PAE] (pmap_bootstrap, pmap_create): 
Allocate 4
                pages for dirbase.  Setup pdpbase.
                [PAE] (pmap_destroy): Free 4 pages from dirbase.  Free pdpbase.
                * i386/intel/pmap.h [PAE] (pt_entry_t): Typedef to unsigned 
long long.
                [PAE] (PDPSHIFT, PDPNUM, PDPMASK): New macros.
                [PAE] (PDESHIFT, PDEMASK, PTEMASK): Set to PAE values.
                [PAE] (lin2pdenum, NPDES): Make them take the page directory 
pointer
                index into account too.
                [PAE] (struct pmap): Add `pdpbase' member.
                (set_dirbase): Remove macro, replaced by...
                (set_pmap): New macro, taking a pmap instead of the dirbase.
                (PMAP_ACTIVATE_USER): Use set_pmap instead of set_dirbase.
