2014-03-03Keep two virtual pages as mapping windows to access physical memorySamuel Thibault

(pmap_get_mapwindow, pmap_put_mapwindow): New prototypes. (PMAP_NMAPWINDOWS): New macro. * i386/intel/pmap.c (mapwindows): New array. (pmap_get_mapwindow, pmap_put_mapwindow): New functions. (pmap_bootstrap, pmap_virtual_space): Reserve virtual pages for the mapping windows. * i386/i386/phys.c: Include <i386/model_dep.h> (INTEL_PTE_W, INTEL_PTE_R): New macros (pmap_zero_page, pmap_copy_page, copy_to_phys, copy_from_phys): Use `pmap_get_mapwindow' to temporarily map physical pages beyond last_phys_addr.
