* DEVELOPMENT: Document Samuel's patch.
2006-05-08 Samuel Thibault <samuel.thibault@ens-lyon.org>
* i386/i386at/model_dep.c (mem_size_init): Limit memory to what can
actually be used (minus a little extra for virtual mappings).
* i386/intel/pmap.c (pmap_bootstrap): Extend the virtual mapping area
according to memory size for at least being able to manage it. But
look out for wrap and limit it to kernel adresses. Remove duplicate
computing.
