cd445195dd cleanup configure options. All paging related stuff is now automatically set/unset according to cpu-level option. 
Related configure options (--enable-pae, --enable-mtrr, --enable-global-pages, --enable-large-pages) are deprecated.
Less configure options - less configure problems :)

071c5c1a26 A lot of changes but everything is really trivial. 
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
