[task #8135 --- ``PAE for GNU Mach'] * i386/configfrag.ac: Add --enable-pae option, which defines PAE. * i386/i386/i386asm.sym (PDPSHIFT, PDEMASK): New assembly 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 of page directory. * 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.
