Starting with the application of the patch from bug #7118, GNU Mach's usage
of the machine's memory equipment is currently forced to be somewhere below 1
GiB, to make GNU Mach work at all on systems with such enlarged RAM
installations.  This is -- of course -- not optimal.  See the calculation of
and with `kernel_virtual_end' and `morevm' in i386/intel/pmap.c and
`phys_last_addr' in i386/i386at/model_dep.c.
